Snorkeler over the reef at Caño Island
El Castillo Arranged Adventure

Snorkel Caño Island

A full day in the water at one of the most pristine marine reserves in the country.

The experience

Crystal water, turtles & reef

Caño Island Biological Reserve sits offshore from the Osa Peninsula, ringed by some of the clearest water and healthiest reef in Costa Rica. After a scenic boat ride you'll slip in among sea turtles, rays, reef fish, and — if you're lucky — white-tip reef sharks.

It's a full-day outing with a certified guide, gear, and time to simply float in the blue. Bring a swimsuit and reef-safe sunscreen; we'll take care of the rest.
