Costa Rica's underwater wonders range from coastal coral reefs to offshore islands. Diving on the southern Pacific-side of Costa Rica is the type of diving adventure most divers only dream of; abundant marine-life ranging from reef sharks to Humpback Whales, Giant Manta Rays to turtles and Puffer Fish to Barracuda - to name only a few. Stretching just 240 kilometres, from the Pacific to the Atlantic Ocean, and 400 kilometres from Nicaragua to the Panama border, Costa Rica is one of the few places on earth to offer an incredible diversity of scenery, climate and adventure opportunities.
