With Cano Island and the Marino Ballena National Park, the Costa Ballena offers some of the best places for scuba diving in Costa Rica. As both locations are natural reserves they contain a rich diversity of corals, reef fish and underwater pinnacles. The Ballena Park’s reef system for example, is one of the least explored marine parks in the world with about 70 kilometers of reef walls and amazing underwater sea mounts. Depending on the season there is also the chance to see very rare animals like sea turtles, reef sharks or even dolphins and whales from the boat. A large number of tours for each level of divers are offered by different providers in the area. Keep in mind that for all dives at Cano Island it is necessary to reserve your space in advance, as duration and the numbers of participants for these excursions are strictly limited to protect the marine reserve´s unspoiled natural beauty.
