Still far too little known, Mayotte is the little treasure of sea-bottom enthusiasts. And for good reason, the island has not one, but two coral reefs, forming a calm and warm lagoon all year round. A particularity that has not escaped the whales, whale sharks, turtles, dugongs, manta rays and dolphins that come to bask in complete safety. If the "lagoon island" as it is nicknamed is a wonder under the surface, it is also very rich on the land. From N'gouja, in the south of the Grande-Terre, Madagascar is only 300 km away. We find baobabs and lemurs whose curiosity outweighs their shyness, to our great delight. Belonging to the Comoros archipelago until 2009, the island has kept its traditions and festivities. Muslim and matriarchal, Mahoran society is cosmopolitan: in the street people speak French, Shimaore, Shibushi and sometimes Malagasy. Women are everywhere, draped in beautiful coloured salouvas decorated with flowers and jewellery. Here laughter is omnipresent and generosity takes on a whole new meaning when the evening comes, when men and women gather around the pike mamas who prepare chicken, manioc and bread fruit on their charcoal barbecues. This tourist guide invites you to discover the two inhabited islands, Petite-Terre and Grande-Terre, as well as the main islets that surround them.
