Los Arcos National Marine Park features diverse underwater terrain for both snorkelers and certified scuba divers.
The waters surrounding the granite islets range from shallow 9-meter (30 ft) reefs to drop-offs exceeding 480 meters (1,500 ft) in depth. This varied environment supports a rich marine ecosystem, including sea turtles, manta rays, and tropical fish.
Most guided tours provide the necessary gear to explore these areas. Early mornings between 08:00 and 11:00 AM offer the calmest waters and best visibility.

Devil's Canyon features a steep underwater trench that drops from 9 meters down to over 480 meters deep. This dramatic vertical drop-off attracts advanced scuba divers. You must hold an appropriate certification to explore the deeper sections of the canyon.
