Cahuita National Park is a 2,711-acre (1,097-ha) national park in the Caribbean La Amistad Conservation Area of Costa Rica located on the southern Caribbean coast in Limón Province, connected to the town of Cahuita. It protects beaches and lowlands and attracts tourists and other visitors who are able to snorkel in the protected marine area which contains the Coralline Reefs, as well as being a nesting ground for sea turtles. February through April typically have the best underwater visibility. This is also one of the nicest and least developed beaches in Costa Rica.
Due to its close proximity to the town of Cahuita, the park's roads and facilities are well developed. Roads access the park from both the north and south. It can be reached on foot via Kelly Creek, which is just south of Cahuita.
Originally the site was created as the Cahuita National Monument in 1970, and was reformed as a National Park in 1978. This change was ratified in 1982. Cahuita National Park also has the distinction of the only national park in Costa Rica not to charge an admission fee (at the Cahuita entrance) and instead relies on donations.
