Isla del Caño

Experience summary

Twenty-two miles off the Osa Peninsula, Isla del Caño Biological Reserve rises from the Pacific like a secret kept for centuries. This sacred island, once a cemetery and spiritual sanctuary for pre-Columbian peoples, is now recognized as one of the finest snorkeling destinations in the Americas. Its transparent waters shelter reef sharks that glide silently along the bottom, sea turtles that surface for air just meters from your face, and manta rays drifting through the deep blue. The white sand beaches shift and disappear with the tides. And from time to time, dolphins and even humpback whales pass through these waters — turning every single visit into something unpredictable and extraordinary.
