This isn't just another dive — it's a choice. Pick your adventure among three of the most legendary dive sites in Isla Mujeres, each with its own story and its own level of challenge.
Cave of the Sleeping Sharks: nurse, bull, and leopard sharks resting motionless 24 meters down, thanks to an oxygen-rich current that defies everything once believed about these species (Advanced Open Water required).
C-55 & C-58 Shipwrecks: two Navy minesweepers intentionally sunk in 2000, now split by hurricanes and reborn as artificial reefs, with grouper, barracuda, and — in winter season — majestic eagle rays, at 24-26 meters (Advanced Open Water plus current and wreck experience required).
Ultrafreeze (El Frío): the deepest, most demanding wreck in the area, resting at nearly 30 meters, with eagle rays, giant grouper, turtles, and barracuda, in a setting reserved for expert divers (Advanced Open Water plus deep/wreck specialty required).
A specialized guide in your chosen site dives alongside you. Additional sites are also available for higher certifications —Atlantis Reef, Jardines Reef, Media Luna Reef, Pailas Reef, La Bandera, Punta Sur, Grampin Reef, and Piedra Atravesada— upon request.

Frequently asked questions
How do I choose the dive site?
Let us know your preference when booking: Cave of the Sleeping Sharks, C-55/C-58 Wrecks, or Ultrafreeze. The chosen site determines whether an additional specialty is required.
Why does it require Advanced Open Water?
Sites range from 24 to nearly 30 meters deep and often have current. Advanced certification (or a credited deep dive) is a safety requirement, not a formality.
Do we go inside the wreck?
We tour decks and wide passages with visible exits. Full technical penetration only with wreck diving certification — ask us if you have it.
Are there really sleeping sharks?
The cave has oxygen-rich upwellings that let sharks stay still and breathe without swimming. Sightings aren't guaranteed, but the site is historic and beautiful in its own right.
Is Nitrox available?
Yes, on request for Enriched Air certified divers. Ask when booking.
