Established in 1960 to protect the reef – with onshore lands added after 1963 – it’s a 70-square-nautical-mile wonderland of corals, sponges, and tropical fish, easily visited on a dive or snorkeling trip with a park-sanctioned outfitter or via glass-bottomed boat.
Not up for the open ocean? A small beach and snorkeling trail serve up a place to splash near shore. The park offers landlubbers fun as well. Start off at the visitors’ center to see the saltwater aquariums, including a 30,000-gallon tank, that orient you to the sea life found on the reef, and then explore the park’s two nature trails to look for tree snails in the tropical hammock and (non-native but huge) iguanas hanging out in the mangrove forests.
