About this site
Nosy Iranja lies off the northwest coast of Madagascar, south of Nosy Be in the Diana region, and is actually made up of two islets joined by a sandbar that is exposed at low tide. Tombant means drop-off or slope in French, suggesting this site follows the underwater terrain along the edge of the island. Dive operators working this stretch of coast typically run trips out from Nosy Be or from camps on Nosy Iranja itself.
