If, like a lot of divers, your inspiration to start diving came from Jacques Cousteau then Cocos Island should be on your radar: he considered Cocos Island to be the most beautiful island in the world.
In 1997 the island, located 550 km off the Pacific coast of Costa Rica became a UNESCO World Heritage Site. Uninhabited, it boasts the only humid tropical forest on a tropical island in the Eastern Tropical Pacific and is one of the most important sites for the protection of large pelagic migratory species, such as sharks, rays and dolphins. Sharks that are commonly found here include endangered and near threatened species like the scalloped hammerhead shark, silky sharks and whale sharks.
Why is Cocos Island a Hope Spot?
Hope Spots are a concept launched by Dr. Sylvia Earle in her 2009 TED talk.
