is 60 km from Fianarantsoa, on the eastern slope of the central highlands, at an altitude ranging from 600 to 1417 meters.

The climate is tropical-humid.

This area was set up in collaboration with important American Universities, in order to protect the high-altitude rain forest where several species of lemurs live (the beautiful Varecia Variegata, the Diadem Sifaka and, above all, the Hapalemur Aureus, only identified in 1987).

Tanala people, « the ones who live in the forest », live in this region that has a dramatic irregular landscape, cut by rivers and beautiful waterfalls.

Close to the park there is an open-air swimming pool filled with water from natural hot springs.
