About this site
Sud Canyon is a wall dive site off Nosy Iranja, the small island pair in Madagascar's Diana region, south of Nosy Be, best known for the sandbar that links its two islets at low tide. Reached by boat from Nosy Be or nearby coastal operators, the site drops along the wall structure typical of this stretch of the Mozambique Channel and is rated an advanced dive. Divers have also reported Beech Cone here, though sightings of it are not a given on every dive.
