Costa Rica is located between the Caribbean and the Pacific Ocean. If you’re looking for top quality diving, then the Pacific side has all the ingredients for a great diving holiday. On the northwest side of the Pacific coast, you’ll find Catalina Islands, Bat Islands and the Gulf of Papagayo. In the southwest of the Pacific, you’ll find some great dive spots around the Cano Island. However, if we had to pick one place, that encapsulates all that Costa Rica has to offer under the surface, then it would have to be the Cocos Islands. The Cocos Islands are approximately 300 miles off the mainland and a UNESCO World Heritage Site. This is a world-class dive site and is the perfect place to see Pelagics including Marlin, Sharks, and Sailfish, which all visit these islands to feed and mate. The Cocos Islands are also home to Hammerhead Shark schools and even Whale Sharks.

Because of its remoteness, the only way to dive at Cocos Island is a liveaboard diving trip.

  1. I made a copy of the report released by the Associated Press saying that the scientist (never say what their names are) are trying to save the coral reefs. The report says that almost half of the coral reefs are dead. Does any body have a conformation on that?
