Best for advanced divers, 16-20m, boat entry, moderate current.
Sleepy Shark Caves, located off Isla Mujeres, offers a complex environment combining reef, cave, and drift diving. Divers navigate depths between 16 and 20 metres, with visibility typically ranging from 10 to 30 metres. The site is characterised by unique water conditions, including higher oxygen and carbon dioxide levels alongside lower salt concentrations. Access is strictly by boat, and the presence of an overhead environment requires advanced training and precise buoyancy control. Divers should be prepared for moderate currents that can shift in strength. Due to the overhead hazards and depth, this site is intended for advanced divers only.
