Much has been written about the most renowned scuba diving destination in Costa Rica, Cocos Island, however liveaboard divers visiting 'the rich coast' can also dive El Caño Island. The diving here is very different from Cocos, but is of such quality as to be considered world-class in its own right.

This amazing marine biological reserve of Isla del Caño lies a mere 10 miles (16 km) offshore from the Osa Peninsula. The reserve’s waters showcase gorgeous coral reefs with good visibility. Show more

How to Dive Caño Island

Caño Island diving is best done from reputable Costa Rica liveaboards to maximize dive opportunities at a variety of sites in the national park as well as those on the periphery.

Our recommended liveaboards to dive El Caño Island are the sister liveaboards operated by the well-established Aggressor fleet. They visit between January and June. Okeanos Aggressor I and Okeanos Aggressor II offer 7 night liveaboard diving tours that include 6 days of diving. All dives are made from tenders. Aggressor provide all scuba divers with personal EPIRBs and have an onboard defibrillator. These added safety measures give you an additional sense of security when you dive remote Caño with Aggressor liveaboards.

In addition to the 20 dives offered during the cruise (including 3 night dives), one of the following land tours are included in the itinerary: Corcovado National Park (San Pedrillo Station or Sirena Station), Sierpe River Mangroves, Caño Island or Drake's Bay Hiking Tour.

Diving Season

Costa Rica is located between 8-12 degrees north of the Equator and has a tropical climate year round. The liveaboard diving season at El Caño Island is relatively short, lasting only 6 months (from January through June) each year. This occurs during the ‘summer’ period which is considered to be more dry than the rest of the year.

The tropical water temperatures range between 72 to 82°F (22-28°C), and you may experience cooler thermoclines. For a comfortable dive, 3-5 mm wetsuits are recommended.
