Chayo’s Cave
Chayo’s Cave: boat-accessed cave swim-through with sea lions.
Plan for a remote reserve island boat day, with a guide-led overhead passage, calm buoyancy needs, and sea lions often at the cave edges.
About Chayo’s Cave
Chayo’s Cave is a boat-accessed swim-through on Isla San Pedro Mártir, built around a short horseshoe-shaped overhead passage. It is a friendly cave-style dive for newer scuba divers who can keep steady buoyancy and follow a guide. Sea lions are often part of the experience near the entrance and exit, so the best dives stay calm and tidy.
