Embark on a captivating journey to Caño Island, one of Costa Rica’s most pristine and protected biological reserves. Located just off the coast of the Osa Peninsula, Caño Island Biological Reserve is widely regarded as the best snorkeling destination in all of Costa Rica — and one of the top snorkeling sites in Central America. The island is surrounded by crystal-clear Pacific waters with visibility often exceeding 20 meters, making it ideal for discovering the extraordinary marine biodiversity below the surface.

Our expert bilingual guides have years of experience leading snorkeling tours at Caño Island and know exactly where to find the most spectacular marine life. Whether you’re a first-time snorkeler or an experienced diver, this tour is designed for all skill levels and ages.

What You’ll See Underwater

Caño Island’s waters are a protected haven for an incredible variety of marine species. During your two snorkeling sessions you may encounter: white-tipped reef sharks resting on the sandy bottom, large schools of colorful tropical fish including parrotfish, angelfish, and surgeonfish, sea turtles gliding gracefully through the reef, spotted eagle rays and manta rays, moray eels peeking from rock crevices, octopus, lobsters, and sea urchins among the coral formations, and dolphins frequently spotted on the boat ride to and from the island. The island itself is also home to rich jungle vegetation and seabirds, making the experience as rewarding above the water as below.
