Part of the Parc National Andasibe Mantadia, this park is located about 17km north of Andasibe. Created primarily to protect the indri , Mantadia also hosts the black-and-white ruffed lemur. A quiet, beautiful area with numerous waterfalls and wonderful landscapes, it is undeveloped and seldom visited compared with its popular neighbour to the south, so if you’re here in high season it’s well worth the detour to escape the crowds. If the weather has been wet (which it often is), watch out for leeches on the trails.
Established circuits include the easy 1km Circuit Rianasoa to see indris , orchids and a natural pool where you can swim (Ar20,000, one hour). This can be combined with the Sacred Waterfall for a 2km, two-hour moderate walk with some steep slopes. The moderate 2.8km Circuit Tsakoka (Ar50,000, three hours) is especially good for seeing frogs, birds and plants, and the Trekking Circuit (Ar40,000, 10 hours), a difficult trail of 15km, offers diverse altitudes and superb landscapes. For more of a challenge, you can also embark on an Adventure Circuit of two to three days, camping in the park (Ar50,000 per day).
Permits and guides can be obtained at the MNP office in Réserve Spéciale d'Analamazaotra. You’ll need all your own camping equipment if you’re planning to stay the night; the MNP camp site (tent sites free), just outside the park, has no facilities. To get to Mantadia from the MNP office, you will most likely need your own vehicle or bicycle. Transport can usually be arranged with park staff, or sometimes through guides and local hotels.
