The Utría National Natural Park is a national park in the Chocó Department, Colombia. It contains diverse flora and fauna in a lush, mountainous rainforest environment with some of the highest rainfall in the world, at up to 10,000 millimetres (390 in) annually. The park also protects the coastal marine environment, and is known for visits by humpback whales, who give birth in the lagoon after which the park is named, and sea turtles who nest on the beaches. There is accommodation for visitors, and ecotourism services are provided by the local indigenous people and members of the coastal Afro-Colombian communities.
