On land, Manuel Antonio is the second most visited national park in Costa Rica, the diversity of animals and vegetation in this volcanic jungle park is famous worldwide. Imagine how the lava was flowing thousands of years ago, from the land and into the ocean, creating reefs and hideouts for all the marine life too. Below the surface, the marine park continues its beauty and amazing thriving life.

The beauty of the reef here is not the corals growing in it, but the topography of the old lava flow. Big boulders, underwater mazes and dramatic walls are what you will be surrounded by. Take these incredible formations and add a healthy marine life to it such as most common reef fish, some funky octopus and a good variety of eels and crustaceans. For the larger pelagic, you might get lucky with anything from reef sharks, rays, sea turtles, dolphins and in season the majestic humpback whales and manta rays (Dec - April).
