There is, first of all, the small Tsingy, bordering the river Manambolo. From this river you can travel by boat to the caves, which were the natural refuge of the first inhabitants of the island from the thirteenth century.

A few kilometers further, we reach the entrance of the National Park of Bemaraha established on 15 000ha, a maze of narrow passages, called joints, the heart of a karst massif with sharp spikes. This series of "waves" mineral is unique in the world and was ranked, in 1990, World Natural Heritage by UNESCO.

The largest protected area in Madagascar offers spectacular treks descents into narrow conduits, climbing (equipped with necessary harnesses and carabiners), passing over suspension bridges to reach lookouts offer magnificent views.

Vegetation that persists to survive in this universe has features such mineral branches and roots which penetrate between the rocks tens of meters. Frogs, small mammals, birds (many Couas) and lemurs inhabit these places.
