Grande Colline National Park, National park in southwestern Haiti

Grande Colline National Park is a 1,510-hectare protected area at the western end of Haiti's Tiburon Peninsula, in the Sud department. It centres on five named peaks of the Grande Colline range, in the Occidental Massif de la Hotte west of Pic Macaya: Morne Desbarrières (1,843 m), Morne Grande Colline (2,025 m), Morne Petite Colline (1,860 m), Morne Grenouille (2,006 m) and Morne Lézard (1,854 m). Above 1,800 m, isolated stands of original forest with giant tree ferns and hardwoods survive.

Grande Colline National Park was created on 23 July 2014, covering 1,510 hectares around five peaks of the Massif de la Hotte, west of Pic Macaya. Its founding followed exploration by the founders of Haiti National Trust between 2011 and 2015, carried out with helicopter support and funded by the National Science Foundation and the Critical Ecosystem Partnership Fund. New species found during that work led to the park's designation.

The park lies in the massif de la Hotte, west of Pic Macaya, and its name comes from Morne Grande Colline, the highest of its five peaks at 2,025 m. Haitians know it as Pak nasyonal Grann Kolin. The reserve is among the most remote corners of the country, reached on foot or by helicopter, and its creation followed surveys by Haiti National Trust between 2011 and 2015.

The terrain demands specialized hiking gear and guidance from experienced professionals, as reaching this mountain area presents serious physical challenges. Visitors should prepare for demanding conditions and arrange support from knowledgeable guides familiar with the area.

The park's five named peaks include Morne Grande Colline at 2,025 m and Morne Grenouille at 2,006 m. Rainfall above 2,000 m can exceed 3,800 mm a year. The area was explored by Haiti National Trust founders in 2011–2015 with helicopter support from the National Science Foundation and Critical Ecosystem Partnership Fund.
