About this site
La Grotte a Nono lies along the coast of Reunion Island, the French overseas department in the Indian Ocean east of Madagascar, in the vicinity of Saint-Pierre on the island's south coast. The shoreline here is shaped by the volcanic rock formations typical of the island, and divers at this site have reported sightings of blackspotted puffer, bluespine unicornfish, Hawaiian convict surgeonfish, and Indian Ocean humbug. Loggerhead sea turtles have also been spotted here, along with Moorish idol, red-cheek wrasse, and both spotted and yellow boxfish.
