Alcyone, Cocos Island

★★★★☆ (447)

Alcyone is an underwater mountain off Cocos Island. Strong to very strong current is always possible. Descent on the rope. There is a maximum depth of 30 meters. Great dive experience required! This is a great dive site that is always worth it as everything is possible here!

Large schools of hammerhead sharks are often seen here (approx. 150 - 200 animals), dolphins, and Galapagos sharks are also not uncommon. Big marble rays are always there.
