About Isla del Caño
Isla del Caño is a protected Pacific marine-reserve dive area off the Osa Peninsula, with clear water, coral reef structure, and a set of named sites that range from easy reef drops to deeper, more technical options. The main value is the wildlife and the reserve setting, but the dive only works well when you plan around the guide, the permit rules, and the boat logistics.

Local Intel For Isla del Caño
Community notes to help plan your visit.
Scuba Diving
Named sites range from reef and anchor stops to a shipwreck and cave profile, so the guide should match certification and sea state.
Freediving
Not the main use case. The reserve's best-known routes are better as guided scuba than as breath-hold diving.
Snorkeling
Snorkelling can still be rewarding in the clear shallows, but the site's main value is the scuba wildlife and structure.
