Established in 1975, Morne Trois Pitons National Park was the first legally-recognized park in Dominica. It was designated a World Heritage Site in 1997. The park's name is derived from the highest peak, Morne Trois Pitons, which translates as "Mountain of Three Peaks". It is the second-highest mountain in Dominica, topped only by Morne Diablotins at 1,447 m (4,747 ft). Surrounded by volcanic activity, the park features the Valley of Desolation, a region of boiling mud pools and geysers, the Boiling Lake, Titou Gorge, and the Emerald Pool.
