Morne Trois Pitons National Park, established in July 1975 by an act of Parliament, was the first of Dominica's National Parks to be legally established.

In 1998, it was recognised by UNESCO as a World Heritage Site - the first enlisted Natural Site in the Eastern Caribbean, and its inauguration was also marked with a Regional conference on The World Heritage Convention.

Luxuriant natural tropical forest blends with scenic volcanic features of great scientific interest in this national park centred on the 1,342-m-high volcano known as Morne Trois Pitons. With its precipitous slopes and deeply incised valleys, 50 fumaroles, hot springs, three freshwater lakes, a 'boiling lake' and five volcanoes, located on the park's nearly 7,000 ha, together with the richest biodiversity in the Lesser Antilles, Morne Trois Pitons National Park presents a rare combination of natural features of World Heritage value.
