Plongée à Cocos Island — Costa Rica
Cocos Island lies 340 miles off Costa Rica's Pacific coast, accessible only by a 36-hour liveaboard crossing — but the reward is arguably the planet's greatest concentration of schooling hammerhead sharks. Mantas, whale sharks, and vast schools of jacks patrol the volcanic seamounts and cleaning stations. This is a true expedition dive destination where you trade comfort for some of the most electric shark encounters imaginable.
