About this site
Big Dos Amigos is one of the well-known rock formations off Cocos Island, a remote national park in the eastern Pacific off Costa Rica reached only by multi-day liveaboard from the mainland. The site is a large rock pinnacle rising from the sea near the island, and dives here typically involve strong currents, which is part of why Cocos as a whole is considered a destination for experienced divers. It is known for pelagic encounters, including schooling hammerhead sharks, whitetip reef sharks, and occasionally larger visitors like Galapagos sharks or rays. Depths and exact conditions vary with the specific dive plan around the rock's walls and swim-throughs.
