Les Tétons is a pair of rocky peaks in the Mitsio Archipelago that break the surface north of Nosy Be. The rock is cut through with arches and caves, and the dive works around the two peaks between 5 and 20 m. Divers come for the colour on the rock and the dense fish life sheltering in its openings.

Also known as Les Tétôns, Les tétons.

The dive

The two peaks emerge above the waterline, and the dive spans the rock between 5 and 20 m. Arches and caves open in the walls of the peaks, and blue triggerfish, snappers, fusiliers and glassfish live in them, while the whole site is colourful and rich in fish.
