There is always one style of diving that most divers are quick to avoid: Cave Diving. It has developed a reputation as being one of the most dangerous styles of diving in the world, and the divers who do it regularly tend to be categorized as insane. This was definitely my thoughts when I initially signed up for my cave diving class. I was constantly told that cave divers were tempting mother nature to flick them into the afterlife at high speed.
So why sign up for a class that you’re scared of? I was looking for a new challenge. After one of my teammates returned from Mexico from his first cave class it was all he could talk about. I joined him in Florida at the GUE Conference last year and decided to test the waters out in Ginnie Springs at The Ballroom. The moment I passed through the opening and saw the whole room open up I was hooked. The feeling of being able to overcome the fear of the unknown was something I truly never thought I would be able to do and it was incredible. Swimming around the room and looking at the rock work, exploring the cracks and crevasses, experiencing a new kind of darkness, it can easily be seen how addicting this could be. The next day my teammate Fred Espino and I signed up for our Cave 1 class in Mexico.
We trained for months diving as often as we could both during the day and night to simulate the feeling of being in a cave. Running line around rocks, a seemingly endless number of valve drills and s-drills, and fine tuning our positioning kicks to make sure we were ready to hit the ground running when we arrived. After every dive I caught myself thinking “are we really about to fly to Mexico and hop into a cave?” I asked myself that question even right up to the point of throwing my carbon fiber backplate into my pelican case the day before my flight.
Once in Cancun, it’s about an hour-long drive to Zero Gravity (ZG). At times the roads can feel a bit like Mario Kart brought to life, but it only added to the sense of adventure we were embarking on. Once we arrived at Zero Gravity, we were immediately introduced to Christopher Le Maillot and Fred Devos, the two owners of Zero Gravity. Between the two of them they have an uncanny ability to make you feel immediately at home.
There are early mornings at ZG. Before the sun rose on our first day we were up and working on our gear. We had dives planned that day to get acclimated to diving in this new environment and some last-minute rehearsals on skills. We arrived at the Dream Gate cenote and were in awe. We briefed and got our gear together with our guide as fast as possible and climbed down the ladders to get inside of the cave. Once in the water, trying to take in this wild moment in our lives, I realized that any notions of fear that I had were completely gone. It was only the giddy feeling you feel as a kid coming down the stairs on Christmas morning.
As we descended into the cavern, we quickly realized how people can get hurt. Caves are the darkest places on Earth, and yet inspire a sense of wonder. As our can lights cut through the darkness, they begin to reveal the true beauty of the cave. The speleothems, or decorations, are some of the most magnificent parts inside of the caves in Mexico. These stalactites and stalagmites are remnants from when the cave was dry before the last ice age. As we swam through the cave, we realized that we are truly swimming through a frozen moment in time. Looking at the walls you can see the different types of rock layers as they were built up over tens of thousands of years.
The next morning, we got to meet our instructor Laszlo Cseh. We spent most of the first day in the classroom going over theory, the history of cave diving, and the basics for why the rules are set in stone. Laszlo seemed to have an endless supply of examples for these rules in real life scenarios which seemed to be calming rather than alarming to us. That afternoon we drove to our first cenote Xtabay where we got to run through safety drills and such to make sure our fundamentals were down before running our first line into the cave. After a few practice runs in the open water portion it was time to try our first line run into the cave.
The cave initially opened up into a massive room with an enormous triangular rock in the middle of it from the last time the roof collapsed. Once we got to the top of the rock, we were able to tie into the main line and do our initial checks of gas, time, and a quick flow check. Laszlo however had other plans for us. Running up and down the line practicing our kicks to make sure they were perfected for our first official cave dive the following morning. Even that little rush of running the line from open water to the main line was amazing.
The following morning, as with every morning, we were up and downstairs bright and early analyzing our tanks and making sure our gear was good to go so we could get to the cenote first. Upon arrival we quickly set our gear up, listened to the briefing by Laszlo, and walked back into Xtabay for our first official cave dive. Fred ran the line in this time and made quick work up to the main line. From there we were able to proceed into the cave.
One of the first things we realized when in the cave is the vastness of it. Shining our lights ahead we couldn’t see where the end of the beam was, even with crystal clear water. Once we left the entrance, we immediately came to what is known as a Halocline. This is where the saltwater in the bottom of the cave meets with the freshwater creating a false ceiling. As you pass over it, it looks like you’re swimming over a pool inside of the cave. This is something that can play tricks on the mind particularly to a disorientated diver on heading out of the cave.
As we swam through it the fresh and saltwater began to mix clouding the visibility to near zero. Once we staggered on either side of the line however we were able to maintain visual contact with each other, the line, and were able to enjoy the 86ºF/30ºC saltwater that we just dipped into.
The colors in the cave were incredible. The blues and greens were striking as our lights slowly moved about the cave. The rock walls were white in the saltwater, and a tan color in the freshwater.
As we moved room to room, I glanced at my computer and realized we’d been swimming for 30 minutes. While that’s not an unusual time for an open water dive, I rapidly came to the realization of “wait, if something goes wrong, we’re going to have to turn around and swim at least another 30 minutes to get back out.” It was this sobering thought that helped me understand the severity of what we were doing. Nothing a few glances around the cave couldn’t snap me out of the thought and continue on with the dive.
As we continued to swim, we came upon a bed plane section of the cave. This is where the cave narrows, but not too small, vertically and can stretch for hundreds of feet horizontally. As we swam forward, we truly started to feel like cave divers. Alas only a few minutes into the dive we hit our turn pressure and had to exit the cave.
As we surfaced Fred and I immediately popped our regulators out of our mouths and exploded with excitement. It seemed like months of hard work and uncertainty finally paid off in that moment, and it was only day two of the class. Laszlo, in his usual Laszlo calm and collected nature, reigned us in with a subtle, “Meh it was ok, let’s see how you do in the cave.” Little did we know the gauntlet that was ahead of us.
Throughout the class we would arrive first thing in the morning, set up our gear, run through dry drills, gear up, and do three to four dives in a day. Upon finishing those we would drive back to ZG and would be in theory for a few more hours before finally being sprung loose for tacos at Marre Marre across the street. They were very long days to say the least, yet every morning we would wake up before our alarms and couldn’t wait to see what the next set of dives had in store for us.
The next few days were filled with every failure that Laszlo and his trusty bubble gun sidekick could think of. From light failures (primary and both back up lights), to regulator failures, we drilled until it became second nature. On one particular dive we were particularly tested. As we swam through the cave just as we were passing through a thermocline I had a simulated primary light failure. After going through the procedures for stowing, deploying backups, etc. Fred and I turned the dive and started our exit. Suddenly he also experienced a simulated primary light failure and had to go through that process. One thing after another happened honing in our focus to the point where we found ourselves in total darkness. As we stayed in touch-contact we moved along the line as a unit. This shows a level of trust in not only your training, but your teammate as well.
Though as the days went on our confidence began to grow swimming around in the caves. Our awareness began to expand to allow us not only to focus on the team, but also begin to actually see the cave. Looking for the jump lines off the main line, seeing more of the details in the room, genuinely being able to take in the vastness and natural beauty that helped shape these caves over millennia.
On the final day we were tasked with two of the most important skills a new cave diver can learn: lost line drill while blindfolded, and gas share exit while blind. These are skills that hopefully a diver never needs to use, however we are going into a hostile world every time we enter a cave, so it’s important to train for every scenario to be prepared for whatever is thrown our way. In a strange way having the blindfold on elicited a sense of calm like I’d never felt. One hand on the line, the other out in front feeling our way out, with Fred hanging onto my elbow, we moved as a unit through the cave, navigating each station (tie off on a rock) as we moved. It felt like a new puzzle each time we came to a station as we moved our way out.
By the end of the day, Laszlo decided that we’d been through enough and we officially were Cave 1 divers. The feeling was hard to describe for a number of reasons. Chiefly both Fred and I had finally reached the moment we had been training for, studying for, and fearful about. We passed. We were officially apart of that group of divers most people think have a screw loose.
Looking back on what we learned and experienced, it’s clear to see that there are really only a few hard-fast rules to follow, similarly and readily transferable to open water dives, which minimize the risk we take on in the caves. First, plan your dive and dive your plan. This includes careful gas planning, and everyone taking responsibility for their own gear, gas, and navigation. Having a continuous guideline starting in open water, so that even in zero visibility you can always find your way out. Maintain your equipment making sure all regulators, valves, and lights are in prime shape to avoid potential problems in the caves. And lastly, ALWAYS be aware of the mainline. With these in mind one can go around the world swimming through the history books in caves and mines exploring what once was and embracing the beauty of what is.

Earlier this summer Jake Bulman and the Protec Team launched their 2023 expedition to Madagascar’s formidable Malazamanga cave known for massive tunnels, formations the size of buildings, and its unbelievable cobalt blue water. They then journeyed to Anjanamba, which despite enormous passageways, consistently turned into tight, restrictive spaces before opening up again. Having appeased the cave spirits and returned safely, Bulman offered up this account.

Deals made. Plans Laid
As I sat in the Paris airport working on my computer, Patrick Widman gestured to me to remove my headphones. He and Phillip Lehmann sat across from me and asked if I wanted to make a deal. Assuming I was walking into some kind of joke, I replied with a hesitant “Sure.” “Next summer you come with us to Madagascar, if you…“ “Yes! Deal, ” I answered before he finished explaining my end of the deal. It didn’t matter, the answer was yes. Patrick finished laying out his already agreed deal, headphones went back in and everybody went back to what they were doing, except for my thoughts, which went to “Holy Shit! I’m going exploring in Madagascar!”
Now nearly a year later in June 2023, we were back in Paris, this time packing all of the bags for the flight to Antananarivo (“Tana”), Madagascar’s capital city. When we got there we met up with Tsoa, who is the local contact, translator, organizer, and overall critical part of the team. Our bags headed to Toliara with the drivers while we spent the day doing some errands.
The next day was important to me, not because i turned 30, but it marked the end of a bet Patrick and I made in 2020, for which I had now won $100. The victory was short lived, however, as I spent that day stuck in my hotel room violently sick. Welcome to Madagascar!
After a short flight, overnight in Toliara, then an hour long boat ride along the coast, we reached Anakao Ocean Lodge. This place is a bit of a shock to the senses after traveling through the poverty stricken cities. Luxury in the middle of nowhere; it would be our basecamp for the trip. As Patrick and I posted a photo of the place, Phillip sarcastically mourned the loss of any “hardcore expedition” image people would imagine.
The next day we planned to meet up with the National Parks’ representatives, organize porters, transport all the equipment to the site, then get in the water and place all of the deco tanks and scooters we would need, and finally be out by dark to avoid being stranded overnight. This may seem overly ambitious, and it was, but is a good example of the overall approach of the project. Always go all in, no shortcuts or laziness, and if it was not possible in the end, no worries at all. The goal is to have fun with the group and do awesome stuff, which we always did.
”This is the most epic cave ever”Phillip Lehmann on Malazamanga
Musing on Malazamanga
Malazamanga, a cave of indescribably massive tunnels, formations the size of buildings, and amazing blue water dominated the first part of the trip. We set up a little basecamp in the mouth of the cave, each of us with our own spaces to change, hang up our suits to dry, and change sorb each day. The entrance swim is a tediously frustrating one for rebreather divers: 20 minutes of low ceilings, bouncing from 20 m to 5 m/66 ft to 16 ft and back several times, never allowing space to sit “in trim”, and no flow to remove any of the inevitable silt that came from passing with multiple scooters, stages and divers.
However, once you reach Ryan’s Chamber, the first big room, you find a staging spot for leaving scooters and tanks for the following day, and a small tunnel leading to the real, intimidatingly massive, Malazamanga.
Patrick and I went to the deep section right away (45-50 m/138 to 164 ft) and spent three days trying to find the way on, while Phillip and Ryan Dart looked around the shallower parts of the cave (20-30 m/66-100 ft) for any leads that had not been checked. Patrick laid line while I surveyed behind him through a wide but low space that became swirling silt and clay by the third tie off. We reached a vertical shaft, Patrick asked me to hold and ran a line into a smaller tunnel below us that led to a restriction. In spaces like this where zero visibility is guaranteed, diver two will be pushing through restrictions blind, having no idea the shape or size of the space around them, which is a recipe for disaster, so I waited on the line for Patrick to return and started a timer.
As fifteen minutes showed on the timer, it started to feel like a long time. How long do I wait before doing something? Five more minutes rolled by, and my mind started to run… What if he has a problem? Does he need help? Memories of having to get somebody out of a similar space once before came to mind. But this time it was Patrick though, if he truly needed help it would be a serious situation. I decided to give him until 30 minutes from when he left, and then I would go in (slowly). With four minutes remaining, a glow appeared before Patrick explained that “it’s tight, but it goes.” It was a long wait that meant a bunch more deco, but this could be the way on.
The next day I was tasked with pushing the End Of Line (EOL) while he and Phillip looked elsewhere. After twisting, turning, removing tanks, and wondering if this was a good idea more than a few times, I pushed through a few ups and downs, but the cave unfortunately ended in a basement section at 52 m/170 ft. No going leads. Time to head home.
Breakthrough and Packing Techniques
Our daily routine started at 06:30 with a breakfast of bread, fruit, eggs, tea and espresso. We’d leave the garage at 07:00, meet the porters at the bottom of the hill in the national park and send the equipment with them. Phil would then educate us on the risks of breakthrough, importance of proper packing techniques, and the impact of dwell time. All of which are critical to making espresso.
After making espresso, the handpresso is put away, we hike the 30 minutes up the hill, get dressed, dive four to six hours, then head home. Back at the garage by 08:00 pm, fill tanks for an hour, eat dinner at 09:00 pm, and then sleep. All the while making jokes, sharing stories, talking about life, trying to blind each other with lights, and being shown the same photo of Rosie, Phillip’s pit bull, with a “look at this awesome photo” preceding the photo display by a few seconds.
All in all, going diving required some effort, not to mention the week of traveling with piles of luggage to get there, the week to get home, and all of the time spent organizing beforehand. In terms of “cost (time/money/effort) per hour underwater” it is some of the most expensive time I’ve ever spent underwater.
One day, after a significant amount of problem solving in the hot, muddy entrance tunnel of the cave, we finally got everything sorted and started doing checks. Halfway through, Phillip said, “I’m not into this. You guys go. Nobody is paying me to do this,” and started to remove his tanks. Considering the “cost per hour underwater,” I think many of us would go whether we wanted to or not, giving in to a sunk cost fallacy-like sense of commitment.
We reformed a plan for the two of us, a few angry birds levels were completed on the surface, and everybody went home excited to see the survey data. There is a lesson to be had here for many of us, about what is actually important and ignoring those perceived, often self-induced pressures to carry on even if it doesn’t actually make sense.
We scoured every corner of the section we were in, until a hole underneath a formation showed a large room on the other side. I tied in at ~40 m/~130 ft, headed down the slope to where floor met wall, removed my tank, locked the reel, threw it through the hole, and headed in. Once my torso passed the squeeze, still inverted in the water, I put my tank back on, grabbed the reel, and swam the direction that I remembered it went. I passed the cloud and made a tie off. Turn, tie off, into a bedding plane, tie off, big room, tie off, and stop.
The floor suddenly featured huge, wavy marks that everybody recognizes as signs of flow. A lot of it. Massive clay bricks fit together like tiles in the riverbed resembling floor. A promising development, I tied off and ducked my head under the lip of the ceiling. Instantly the ceiling met the clay bed and the cave ended. Water unfortunately doesn’t consider human size in its choice of direction. Back to the drawing board.
“Fuck it, let’s just see what happens”Patrick Widmann
To Breathe or Not To Breathe
At the time, the furthest reaches of Malazamanga was an enormous collapse with no way beyond it except a few air domes. We were aware the air domes may not be breathable, but lacked a proper analyzer for that. After some thought, Patrick decided that we would just give it a go one at a time. We surfaced and knelt close together as Patrick closed his DSV and took a short breath of the gas. Wearing an expression resembling somebody tasting less-than-appetizing looking food he took a second breath.
Watching intently, I saw the expression quickly change from hesitant but ok, to uncomfortable to concerned as he put his DSV back in and opened it. I was ready for him to pass out as we sat there breathing, but nothing happened. We knew it was likely not breathable, but I wanted to see what it felt like! I removed my DSV and took a breath. A humid, thick, shockingly hot breath filled my lungs and I was not going to take a second one. No way that was safe, I thought, as the burning in my lungs slowly faded.
Patrick climbed out with just his rebreather (and flowing oxygen) and took a quick look around, but no luck. As he was getting dressed again, I popped my head into a few holes and found a passage that looked to slope downwards on the other side of a tight squeeze. I ran a line in with Patrick behind me, and tried to push through but couldn’t fit. After removing myself and the cloud of unavoidable silt surrounded us, I grabbed the rock that was in the way and flipped it over. If you have ever moved a big rock in a collapse, in a never-before-dived cave, you can imagine the visibility afterwards. We backed out, went to check a few other places, then returned hoping for slightly better visibility.
Patrick was the next one in, leaving a tank on the line with me this time, and he extended the line down the slope on the other side. I heard rocks falling, tanks banging on rock, grunting, laughing, bubbles moving along the ceiling, and then he returned with his hands shaking like crazy. Whatever was over there, was not for the faint of heart it seemed. After a bit of cooling down, he went back into the cloud, which was followed by loud yelling. Excited yelling. We exited, and planned our return for the next day. What lay beyond the 6 m/20 ft deep, vertical, awkward, tank-off restriction was an open space that continued downwards to what appeared to be 40 m+.
The next day, I was going through first. We rehearsed the shape of the restriction and the series of movements needed for passing it on the surface. It was weaving through the space where collapsed boulders met the sloping ceiling, and any extra force on the wiggling rocks meant possible collapse. The plan was for me to pass, tie into the EOL, and head off. Patrick would pass behind me with the MNemo and survey in. Adding tie off after tie off, I headed deeper, then flattened out, then up through an opening to my right. Now it was my turn to yell, the cave had returned to its previous enormous size!! This celebration lasted three tie offs, as we climbed yet another collapse that was quite clearly the end. Cut line, put reel away, look around knowing that nobody will ever be here again, and head home.
On to Anjanamba
Several options lay ahead of us, which Patrick and Phil weighed over dinner. Continue searching in Malazamanga, or get the filming done then head north to Anjanamba, or spend the next two weeks surfing. The last option was apparently way more valid than the joking suggestion I had taken it as. Fortunately, the second option was the choice. We spent a day scootering around with lights in hand and on the DPVs. Screen grabs of the video were used as photos for this article.
We also had two surfing days, where I (having never surfed before) mostly tried to not get annihilated by the waves. My second goal was “not to kill anybody” as Patrick and Phillip repetitively warned me not to do it with my oversized board (only a stand up paddle board was available). Fortunately I’m a very strong swimmer, as I spent large chunks of time crashing and burning, then being tossed around by the ocean.
”This is the most epic cave ever”Phillip Lehmann on Anjanamba
Heading up to Anjanamba featured a boat ride, a seven hour drive that resembled one of those truck commercials trying to show how tough its product is, and a journey through the Mikea National Park which had no paved road either. During lunch break everybody commented how much better it is now than it was several years ago, describing it as “pretty smooth” and “less violent” in the same sentence.
We visited the local village, where residents are the spiritual keepers of Anjanamba, to talk to the chief and say hi to a friend of Tsoa who had just had a baby. While there we got a tour of their newly built school, joked with the children a bit, took a photo and headed home. For a lifestyle that is so drastically different to our own, with so much less of everything tangible, the village seems a happy, lively place with kids running and playing. However it is easy to see the need for food, schooling, health products, and basic medical care to name a few.
Appeasing the Spirits of Anjanamba
Anjanamba is the location of the filming of the “Spirits of the Cave ” series (see DIVE DEEPER below). Described as a much more dendritic, Mexican-like cave with a blue color that puts the famous Mexican salt water tunnels to shame. The name of the series doesn’t come from nowhere; this cave is home to several spirits. In order to appease them, a few things need to be accomplished.
First, we must visit a big, double trunked baobab during the walk there. We remove our hats, gather near the meeting point of the trunks, place a pointer finger on one tree and pinky on the other (think bull horns hand shape), bow our heads and ask the spirits for two things. One, that they allow us to find an epic cave that goes. Two, that they grant us safe passage and everybody returns home safely. The ever-present, always watching lizard that lives there looked down in approval. The locals however, who had no idea what we were doing, waved us back to the path with a smile and laugh.
Once that is done, a ritual must happen with the Mikea people (in which the National Park is named after). Patrick and Phil have already been through it, so it’s just me. The chief started the ritual, as they each took a sip from a bottle of rum we had brought. Tsoa explained to me afterwards what they had been saying (asking the spirits to accept me, safe passage etc). Notably, it included nothing about finding mega cave, but we had already covered that during the lizard tree ceremony I guess.
The guys had warned me about the second part of the ritual, which had me eating a part of the cave – sand, dirt, rock, whatever. The chief continued speaking, and Tsoa told me it was time. I pinched some sand, put it in my mouth and swallowed. Phillip verified it was all gone. In the background I hear Patrick stifle a laugh, and my long-held suspicion was proven true, this was not actually part of it. The locals found it hilarious, and it wasn’t as if I was going to say no in any case. Diving time.
As usual, we were quite late and had made very ambitious plans which didn’t quite pan out. But we did as much as we could, then headed back to our new home at “Laguna Blu.” Like in Anakao, we had great food, friendly staff, beautiful views and comfortable sleeping.
Having laid less line than we had hoped in Malazamanga, we were keen to “bash some reels”. Anjanambas current EOL lay at more than 2287 meters/7500 feet with an average depth of 18m/60 ft or so. It featured enormous tunnels and decorated rooms, yet consistently turned into tight, never-quite-ending spaces before returning to vast rooms with pristine formations all over the place.
Patrick and I each carried a stage, and I carried the back up scooter. Passing through the 30 minutes of sideways swimming, weaving up and down, belly scraping, up and down cave with a negatively buoyant scooter in between my legs meant it was not always smooth sailing. Fortunately it usually got stuck when I was in the back so nobody saw. We reached the end of the line, Phillip tied in and headed off with Patrick recording and me surveying behind them.
From my POV, it looked likely to end every 10 tie offs only for the line to weave into a little corner of the room and continue, with nothing but a light dusting of silt at each tie off as signs of my team ahead of me. This repeated for another 457 meters/1500 ft of line until the reel was emptied, everybody cheered and fist bumped with excitement and then decided that we really needed to head home.
Our DPV charging plan didn’t pan out, so after each day Patrick and Phil drove over to a neighboring location and ate lunch while the scooters charged. I went back to Anjanamba and swam some of the closer lines checking for any going cave. After extending a few EOL’s, the sections had been checked without much luck. After a few days of exploring in Anjanamba, which mostly featured a repeating pattern of restrictions then big rooms, we finished our last diving day with nothing clearly going, but a few hopeful areas left.
End of the Line
As we reached the end of the trip, instead of feeling tired as we expected, we found ourselves ready for more. We had lots of sorb left, but had used every last liter of oxygen. Unfortunately, it was time to take a group photo with the locals, dry our equipment and start the journey home. Not only did we have flights to catch, but we had classes to teach less than 12 hours after landing in Mexico.
After five weeks of expedition, we had managed to get the most out of every day, be on time almost never, and explore some amazing cave. More impressively, I don’t recall a single argument or bad mood at all, which is rare when you spend 18 hours per day with the same people. Until next time, the villagers return to their normal lives, we go back to the Caribbean, and the spirits of Anjanamba can rest again.
We did have one last day before heading home, in which we would make a discovery. What will come of it is yet to be seen, but I’m sure it’s going to be a mega-epic either way. In fact, probably the most epic cave ever.
