Isla del Coco
Isla del Coco was described by Jacques Cousteau as “the most beautiful island in the world”. A Unesco World Heritage Site 300mi (483km) southwest of Cabo Blanco, it’s Costa Rica’s most exquisite marine park and one of the top diving destinations in the world. However, it’s best reserved for experienced scuba divers with a truly adventurous spirit. The only way to access the island and its phenomenal dive sites is via a live-aboard boat excursion. Once you get there, Isla del Coco is famous for its scalloped hammerhead populations, as well as multiple other types of shark, whale, dolphin, ray and tropical fish.
