Andasibe-Mantadia National Park, National park in Toamasina Province, Madagascar.

Andasibe-Mantadia is a protected rainforest area in Toamasina Province in eastern Madagascar, covering elevations from 800 to 1260 meters. The park consists of two connected sections that preserve different forest types and support diverse wildlife.

The site was created in 1989 by merging the existing Mantadia National Park with the Analamazoatra Reserve. This combination strengthened protection for the original rainforest and its inhabitants.

The name Andasibe comes from the nearby village, and the reserve is also called Analamazaotra or Périnet. The Betsimisaraka, Bezanozano and Merina peoples live in the area. The Analamazaotra reserve is known for its indri population, and guides from the local community lead visitors into the forest.

To visit the park, travel from Antananarivo using Route Nationale 2. A local guide is required for any exploration and will help ensure your safety while showing you around the area.

The indri is Madagascar's largest lemur, not a monkey or ape. Since 2006 the Analamazaotra Re-introduction/Translocation project has moved diademed sifaka and black-and-white ruffed lemur here from threatened habitats; by 2014 it had released 26 sifaka and 8 ruffed lemurs, and two generations of babies have been born in the reserve.
