Ecco la storia originale così com’è stata scritta in italiano
Author’s note: I do not encourage other divers to conduct solo diving. The trip and the dives described in this article were conducted after significant training and experience.
Ed.Note: Global Underwater Explorers does not sanction solo diving.
That was the feeling I had last June 2020 when I left my home to begin a journey alone. Caves, abandoned mines, alpine lakes, and a few wrecks—that was my plan for a great adventure.
The first COVID-19 lockdown had been in place for a couple of weeks, and I was afraid of going out and meeting people. Social distancing left an open wound. I loaded my wreck-van with plenty of stuff to survive alone for a long month traveling amongst rivers, lakes, mountains, and forests, and I was ready to practice scuba diving.
At that time, tourist travel was impossible in Italy or abroad—anywhere in Europe—because the coronavirus had locked the borders. I asked an editor in chief from a magazine—one whom I am used to sending articles to—to prepare a couple of official invitation letters for customs. For my trip, I converted my wreck van into a cave van. It was fully equipped with a 300-bar air compressor, helium, oxygen, deco cylinders, twinsets of different sizes, gas booster, fins, mountain boots, tent, camp burner, and brand-new dry suits, as well as thermal underwear to be tested for my company PHY Diving Equipment.
I remember the day well. I was thrilled as I crossed the border between Italy and Slovenia. I had been restricted to nothing but a 200 m/650 ft walk from my house because of the pandemic restrictions, but with an eight-hour drive, I was free to enjoy walking into wild nature all alone.
The mental switch was awesome, and unexpected. I did make just one phone call from abroad. I talked to an incredible Russian who was the first guy I met in a small rural village in Slovenia. He had emigrated some years ago, and now he welcomed travelers by sharing his farmstead.
However, once I arrived on site, I was not very welcomed by the weather; instead, I was met by heavy rain. After the storm passed, I went out walking and filming with my phone. I had decided to record all of the trip. As luck would have it, the rain returned again, and it never left me for the entire duration of my trip (almost a month).
My tour was articulated throughout Slovenia, Garda Lake (Italy), Austria, and South Tirol’s Alps, Tuscany’s caves, and finally I reached the central part of Italy—Appenini mountains and their peaks. I planned to reach two mines, but heavy rains stopped my dream. Excluding Slovenia, where I slept in a traditional bed, I passed all my time living in my tent. Cold weather and storms were my constant companions.
I managed to see a ray of light for just a few hours, I never had any chance to dry my equipment, and I warmed up inside my van. Every night I slept only a few hours because of loud wind noise or strong rain storms. Day-by-day I grew tireder and more feeble. One day, three weeks after I left home, I was in South Tirol descending a mountain when I decided to conclude my trip, and I returned home safe.
The goal of my trip was to tell scuba adventures from the surface point of view where the water is only a part of the context and not the objective. I made a mini-series film composed of three chapters. Each one brings you inside the scene. What follows here is the first episode of the trip.
Social Distancing Beneath The Slovenian Soil
The first day of cave diving in Slovenia was very tricky and full of adventures. I had no idea how the second day would go.
I left my accommodations around 6 a.m., after a good breakfast of cereal, dark chocolate with black coffee, dried fruit, and tasty Italian Parmesan cheese. I could not see anything from my window because what had fallen was not simply rain; it appeared to be an awesome flood. My plan for that day had been delayed.
I think that most parts of dry caves are condemned for hundreds of kilometers. So, I decided to check the weather forecast and water level conditions in caves close to the Croatian border. It would mean driving about four hours to see for myself whether scuba diving was allowed. I didn’t have to remind myself, I was alone here.
Wheels were on the road and local conditions seemed quite good. I had checked the weather on my laptop and understood the risk. If I was lucky, I could dive; if not, I would have to drive back. I drove through Slovenia forest meeting no one. With less than an hour left to my destination, I came across an abandoned farm village, completely empty.
The dive inside Bilpa Jama was breathtaking. Now I was seated beside the cave shore preparing soup to warm myself. After a stunning solo dive, I was cold and wanted only to taste the peace of this magnificent place. While I was dipping the spoon in my soup cup, I heard a faraway voice, a police woman calling me and asking me to stop eating and come quickly to her.
After I did as I was asked, she started examining my passport, documents, and permissions. A few minutes later, a huge National Army truck reached us. The soldier had an abnormal body shape, a man the size of a walking mountain in an Army uniform. Can you imagine how I was feeling in those moments?!
Well, in the end, everything went really well, and I now have a story to tell my grandchildren.
Once the passport control was over, and they had checked that I did not cross the border from Croatia to Slovenia illegally (customs was only a few hundred meters from us), I had the chance to get back to my soup, which by then had turned cold. I warmed it up again, and I spent half an hour seated on a slippery stone covered with moss and lichens watching the beauty of the forest surrounding me.
On the way back to my accomodations in my cave van, I played a new playlist.
Four hours later, I approached my country lodge. I was really exhausted, but I had to refill tanks and plan the next scuba diving days. Once I finished, I watched the forecast again. Unfortunately, it was growing worse, so I decided not to dive and instead get a surface break. Tomorrow I would drive, search, and catch info and GPS coordinates of caves. My tomorrow plans had turned into a sketching and surveying day.
The Road To Suha Dolca
I drove and walked for hours and hours, up and down the forest or on lonely roads in search of caves where I could return in winter or perhaps next year. During the last survey of the day, I watched a talented young guy playing a traditional concertina and thought, what a lovely atmosphere and a fitting way to close my hard-working day!
I decided to give a last gaze to Suha Dolca cave, my favorite one, on the way home. This was the third consecutive day I had arrived back at this spot. Observing it day-by-day, I tried to find the best moment to dive this cave.
Until now, it was inaccessible due to the strong flow. I wanted to dive here before leaving Slovenia. Tired and driving slowly, I parked my van away from my accommodation. Since I had no lunch, I started feeling very hungry. A simple dinner was quickly served: dried fruits and a cup of hot noodle soup.
My ‘NO DIRECTION HOME’ trip was now at its peak. I had become a wanderer. I was alone in a wild country with, yes, an internet connection for historical research and checking the weather. That was the only technology I used. Aside from that, I lived simply. I walked, dived, wrote, and filmed my experience all with my mobile phone.
Rain was tougher than expected. I had hoped to stop for one day, not the two that it took. Following the surveys, the next day I started fixing my video equipment and saving photos and videos I had made on my hard drive.
I had too many ideas, no one clear till the end, and too many cave sketches and GPS points to reorganize; I needed a day to regroup. I just went out for a few hours to check Suha Dolca’s Cave conditions. On this day it seemed that the flow was getting more stable, and general water conditions were growing better. I had to be patient and wait one or two days more for the right conditions. I tried and failed to find a solution on my own, but the water always showed me the way. She told me to wait and to go back to where I came from. Step-by-step I walked the path again.
The third video chapter of Slovenia Solo Cave Diving is the one I prefer, because I remember the indecision I felt, to stay or to leave. Solo trips are strictly linked to life’s decision.
The last day I was in Slovenia I left the accommodations and asked a new farmer, close to a different cave, if I could sleep inside his barn and dive the river hole on the following day. I was at the same place where I had dived the first day. He told me I could not stay in the barn due to the high risk of bears who live in the surrounding area. I jumped in my van again and I drove to the lake beside Suha Dolca’s Cave.
I descended the path several times and brought all my scuba gear piece-by-piece. I decided to give myself a chance to dive my dream cave in the late afternoon. I had no other choice. Once I was inside the cave it was unbelievable, and I had a very nice dive even though I was really tired, and again I broke my light arms and camera housing. I resurfaced after the dive into a reed’s lake, which made me feel like a beaver.
I had conflicting feelings as I left Slovenia that same night after making a tricky and stunning dive. Bears, awesome forests, and rural areas were now all behind me. The cave-van played a new disc, I needed to shake off these feelings and look forward to my new goals: Garda Lake’s wrecks, South Tyrol’s stunning lakes, and finally Austria. In the country of green and wide grazing land I wish to dive surrounded by the amazing scenario of beautiful Alps mountains.
At 9:30 PM I crossed the border again, and Italy was straight ahead.

Karen van den Oever Continues to Push the Depth at Bushmansgat: Her New Record—246m
Karen van den Oever recently broke her own world cave diving depth record by a little more than 10m/33 ft at Bushmansgat cave in South Africa. The S.African cave diver conducted the 8 hour 14 min high-altitude dive on open circuit scuba, breathing trimix 4/90 bottom mix, and suffered mild High Pressure Nervous Syndrome (HPNS). Here former world depth record holder, Nuno Gomes who was van den Oever’s cave instructor, offers the details of her record setting dive along with a short history of the women’s depth records.

Karen van den Oever, from Johannesburg, South Africa, has dived to a depth of 246.65 m/809 ft. This is equivalent to a dive to a depth of 296 m/971 ft when corrected for an altitude of 1550 m/5,085 ft above sea level. The dive was conducted on October 27, 2022, in Bushmansgat cave, South Africa, and is a new women’s world record cave dive. Karen bettered her own previous world record to a depth of 236.04m/770 ft (283 m/924 ft correcting for altitude), also accomplished at Bushmansgat cave in 2021.
“I actually felt really good after the dive, a little tired but overall, quite good. I felt much better after this dive than the previous one. I’m happy that the dive went well, just thinking about what comes next. I have no definite plans going forward, we are looking into diving some of the caves in Namibia and also exploring some of the caves not yet dived in Zambia but no concrete plans yet.”—Karen van den Oever
Women have been making record deep dives for quite some time. Back in 1981, one of the first deep diving records was made by Sheck Exley’s wife, Mary Ellen Eckhoff (USA). She used a dive propulsion vehicle (DPV) to travel into Wakulla Springs cave, as well as staged tanks for decompression purposes. Mary Ellen dived on open circuit, together with Paul DeLoach and John Zumrick, and they reached a distance of 363 m/1192 ft and a depth of 80 m/260 ft, which was a major dive at the time.
In 1996, Dr. Ann Kristovich (USA), a friend of Jim Bowden, considerably extended the record, reaching a depth of 167 m/548 ft on open circuit at Zacaton cave, Mexico. Ann’s world record dive would remain in place for a long time.
It was not until the year 2000 that another woman, Claudia Serpierri (Italy), would beat the previous record, but this time in the sea (Mediterranean Sea). Claudia would reach a depth of 211 m/692 ft on open circuit, diving from a support ship. This dive remains the deepest sea dive by a woman to date.
Toward the end of 2001, Verna van Schaik (South Africa), was ready to challenge the women’s record. First, she did her deepest dive by reaching a depth of 186 m/610 ft (223 m/732 ft correcting for altitude), on open circuit, at Bushmansgat cave in South Africa. This was not enough for her, and during her next expedition on October 25, 2004, Verna would go back to Bushmansgat cave to become the first South African woman to get her name in the Guinness Book of World Records by reaching a depth of 221 m/725 ft (265 m/870 ft altitude corrected), on open circuit. Her deep support diver was the late Dave Shaw (Australia), on closed circuit, who died of respiratory insufficiency at a sub-250 m dive at Bushmansgat in 2005.
Following Verna van Schaik’s dive at Bushmansgat cave, two women divers died trying to break her record, as follows:
In May 2010, French diver Brigitte Lenoir, died in Dahab, Egypt during a dive in the Red Sea. The accident took place at 147 m/482 ft while ascending from a 200 m/656 ft, on closed circuit. Her body was recovered with an ROV.
In September 2017, Bulgarian technical diving instructor trainer, Teodora Balabanova, died attempting a dive to 231 m/754 ft, on open circuit, while her husband, Mihail Balabanov, suffered from decompression sickness.
Karen van den Oever is a science graduate from the University of Witwatersrand in Johannesburg, South Africa, where she currently resides. Like Verna van Schaik, who now resides in New Zealand, she is a CMAS diving instructor, and also a former member of the University of the Witwatersrand Underwater Club.
Her original cave, trimix and blending training was with me. I also trained her husband Francois Bain.
Karen had previously dived to 201 m/660 ft (241 m/792 ft altitude corrected) on open circuit in Bushmansgat cave in South Africa’s Northern Cape province on February 27, 2020. That dive’s total dive time was 7 hours and 21 minutes. On March 26, 2021, Karen dove to 236.04 m/770 ft (283 m/924 ft), on open circuit, at Bushmansgat cave, using a bottom gas of trimix 6/85. The total dive time was 7 hours and 18 minutes. That dive is the current deep diving Guinness World Record (women).
Karen’s new world record dive, done on October 27, 2022, was made to a depth of 246.65 m/809 ft (296 m/971 ft), in Bushmansgat cave. The dive was done on open circuit, using a bottom gas of trimix 4/90, and with a total dive time of 8 hours and 14 minutes. The dive would not have been possible without a large team of support divers.
Peter Reid was at 209 m/686 ft (251 m/823 ft); this was his personal deepest dive on closed circuit, and his total dive time was 6 hours and 20 minutes. Don Hauman did deep support at 110 m/361 ft (132 m/433 ft). Her husband Francois provided shallow support and surface support, together with the other team members.
Karen’s Total Narcotic Depth (TND) was 48.06 m/158 ft; the Equivalent Narcotic Depth (END) considering nitrogen only was 9.49 m/31.14 ft, and her maximum Partial Pressure of Oxygen (PO2) was 1.03 Atm. Gradient factors: 40/75.
There were no serious incidents during the dive except that Karen suffered some mild High Pressure Nervous Syndrome (HPNS), which ultimately did not prevent her from going any deeper. Karen had some difficulties recovering the evidence tag from her maximum depth because of the tremors that she was experiencing as a result of the HPNS, but in the end she turned the dive mainly because she ran out of bottom time.
InDEPTH: Opinion: Don’t Break That Record
Nuno Gomes is a professional civil engineer, a CMAS technical diving instructor and a commercial diver. He was born in Lisbon, but his family relocated to South Africa during his youth. He now lives permanently in New York with his family. He has dived all over the world.
He used SCUBA (open circuit) to dive to a depth of 321.81 meters (1,056 feet), inclusive of rope stretch, in the Red Sea off the coast of Egypt near Dahab, in June 2005. The total dive time was 12 hours and 20 minutes. The descent took 14 minutes with two minutes spent at the bottom.
He also used SCUBA (open circuit) to dive to 282.6 meters (927 feet) in the Bushmansgat cave, in South Africa, in 1996. The cave is located at an altitude of 1,550 meters (5,086 feet) above sea level, which resulted in a decompression schedule for an equivalent sea level dive to a depth of 339 meters (1,112 feet) in order to prevent decompression sickness. The total dive time was 12 hours and 15 minutes with four minutes spent at the bottom of the cave.
