The boat captain idles engines while you step carefully from bow to boulder, finding purchase on algae-slicked rock. Playa Muertos occupies a crease in Tortuga Island's southeastern flank, more geology than beach—stacked volcanic stones creating tide pools, caves, and underwater passages. The shore receives no sand deposits; waves have polished the basalt smooth and black, and barnacles colonize anything above the low-tide line.
“The only Tortuga Island beach where volcanic geology completely dominates, creating underwater caves and exceptional marine habitat without a grain of sand.”

You pull on fins and drop into water the temperature of brewed tea. Visibility stretches to twenty meters on calm mornings. Below, the rocky substrate creates habitat complexity: schools of blue-striped grunts hover in the water column, spotted morays thread through crevices, cleaning gobies work their stations on coral-encrusted boulders. You follow a channel between rocks and find yourself in an amphitheater of stone, ceiling open to sky, walls alive with Christmas tree worms and feather-duster fans. A green sea turtle lifts off the bottom and glides past your mask, close enough to count the scutes on its carapace.
The beach's morbid name comes from shipwrecks—colonial-era galleons and modern fishing boats alike have foundered on the Tortuga reefs. Locals still occasionally find ballast stones and iron fittings washed into the rocks. You surface between dive sessions and perch on sun-heated basalt, watching frigatebirds ride thermals overhead. This isn't a place for long lazy beach days. It's an in-and-out snorkel mission, a geological curiosity, a swimming hole with history soaked into its stones.
