Cueva del Tiburon (Cano Island)
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily — treat everything here as planning ranges.
Shark Cave keeps Cano Island's promise at a gentler register than Bajo del Diablo. The name comes from a broad recess in the granite where whitetip reef sharks pile in to rest through the day - divers kneel on the sand at a respectful distance and watch a shelf of sharks breathe, stack, and occasionally reshuffle like badly filed books. Around the ledges, the reserve's protected biomass fills in the rest: parrotfish, big porcupinefish, morays, turtles on the rock line, and eagle rays gliding the perimeter. Shallow depths, mild current, and reliable clarity make it the reserve's best introduction dive, and a favorite second tank after the pinnacles.
The moment you come for: Resting whitetips at close, calm range, easy profile in the reserve's clear water
Topography: Low granite reef with ledges, overhangs, and a shark-sheltering recess
Know before you splash
Hazards: Surge into the ledges on swell; mind fins near the resting sharks.
Conservation: Do not crowd or block the resting recess - the sharks abandon it when pressed.
