About this site
Nosy Valiha lies off the coast of northern Madagascar, in the waters near Nosy Be, a region known for its volcanic island geography scattered along the Mozambique Channel. "Tombant" is the French term for a drop-off or wall, suggesting this site follows a sloping or vertical rock face typical of the volcanic terrain around these islands. Dive operators based out of Nosy Be and nearby coastal towns commonly run trips to sites throughout this island group.
