Current-velocity research for the Sodwana Bay coelacanth canyon system.
Jessor Canyon Cave is a deep technical boat dive in Sodwana Bay.
Jessor Canyon Cave is a deep technical boat dive in Sodwana Bay.
Jessor Canyon Cave is a deep technical dive in Sodwana Bay's Jesser Canyon, where a steep reef wall drops into a cave system famous for coelacanth sightings. The draw is the canyon wall, overhangs, and cave habitat rather than a casual reef tour. Plan for permit-controlled access, trimix-level planning, and a site that only suits very experienced divers.

Weather-dependent surf launches, clear tropical water, and a very deep technical profile.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Only qualified technical divers with permit and deep-gas planning should consider the cave; coelacanths must not be approached or harassed.
Access Restrictions
Permit-controlled technical dive; trimix competence required, and coelacanth encounters are protected.
Legal Notes
Inside iSimangaliso, canyon diving and coelacanth habitat are subject to conservation permit controls.
Community notes to help plan your visit.
Scuba Diving
The appeal is the deep canyon wall, overhangs, and cave habitat rather than a broad reef swim-through.
