Discover Caño Island Biological Reserve, one of the best destinations in Costa Rica’s South Pacific for snorkeling and scuba diving. Its crystal-clear waters and coral reefs provide excellent visibility year-round thanks to its offshore location. During the green season (May to November), nutrient-rich waters attract large pelagic species, making every dive even more rewarding. For the ultimate nature experience, combine your visit with Corcovado National Park, where one of the most biodiverse rainforests on Earth meets the sea in a truly unique spectacle.

This experience supports responsible tourism practices through local partnerships, respect for wildlife observation standards, and experiences connected with Costa Rica’s natural and cultural heritage.
