This national marine park contains Panama's largest island, the 503-sq-km Isla de Coiba, as well as astounding biodiversity; more than two dozen species of dolphin and whale have been identified, including humpback, killer and sperm whales. Several species of crocodile and turtle, and 15 species of snake roam the island as well as myriad birdlife. Santa Catalina is the best place to base yourself if you're interested in reaching the park.
