Slip through a sea tunnel to reach the legendary hidden beach — a collapsed volcanic crater with its own private sky. Snorkel pristine reefs teeming with tropical fish and rays in a UNESCO-protected biosphere.
What to expect
A 45-minute catamaran crossing to the Marietas Islands sets the scene before guides lead you through the sea cave tunnel at low tide into the jaw-dropping hidden beach crater. You'll snorkel the crystal-clear biosphere waters among parrotfish, sea turtles, and rays. A gourmet open bar and fresh ceviche lunch on deck round out the journey back.
