About this site
Nosy Valiha lies off the northeast coast of Madagascar, in the Antsiranana region near the Nosy Be and Ankarea archipelago area of the Indian Ocean. "Tombant" is French for a drop-off or wall, suggesting this site follows a sloping or vertical reef feature along the island's edge, reached by boat from the surrounding coastal settlements.
