Boesmansgat (or Bushmansgat), also known in English as "Bushman's Hole", is a deep submerged freshwater cave (or sinkhole) in the Northern Cape province of South Africa, which has been dived to a depth of 282.6 metres (927 ft).
Boesmansgat was believed to have first been explored by amateur diver Mike Rathbourne, in 1977. The greatest depth attained was by Nuno Gomes in 1996, diving to a depth of 282.6 metres (927 ft). Its altitude of over 1,500 metres (4,921 ft) makes this a particularly challenging dive, requiring a decompression schedule equivalent for a dive to 339 metres (1,112 ft) at sea level. Gomes' dive was a close call, as he got stuck in the mud on the bottom of Bushman's Hole for two minutes before escaping.
On 24 November 2004, Verna van Schaik set the Guinness Woman's World Record for the deepest dive by diving down to a depth of 221 metres (725 ft).
In October 2022 Karen van den Oever broke her own Guinness World Record as the world’s deepest diving woman when she descended to 246.65 metres (809.2 ft) using open-circuit equipment.




Deaths


In 1993, Eben Leyden died after blacking out at a depth of 60 metres (200 ft). Leyden was brought up immediately by diving buddy Boetie Sheun but could not be revived.
In 1994, while helping a team prepare for a dive, Deon Dreyer died on ascent at a depth of 50 metres (164 ft). Dreyer's body remained in the cave until being discovered ten years later at a depth of 270 metres (886 ft) by cave diver Dave Shaw.
On 8 January 2005, Dave Shaw died after becoming tangled in the line while attempting to recover Dreyer's body. (Shaw's close friend and support diver, Don Shirley, nearly died as well and was left with permanent ear damage that has impaired his balance.) On 12 January 2005, Dreyer and Shaw's bodies were ultimately recovered near the surface, while members of the dive team were recovering technical equipment, which included a camera that filmed Shaw’s last moments in the water.




In literature


In Mo Hayder's novel Ritual (2008), the death of the parents of one of the protagonists while diving in Bushman's Hole is an important plot device.




In media


The 2005 attempt to recover Deon Dreyer's body that led to the death of Dave Shaw is the subject of the 2020 documentary Dave Not Coming Back.
