Mauritius sits atop the Mascarene Plateau, a volcanic chain that rises three thousand metres from the Indian Ocean floor.
The island's eastern and northern coasts are fringed by lagoons shallow enough to wade across at low tide, their turquoise clarity a consequence of coral reefs that ring the shoreline and break the swells. A private catamaran cruise Mauritius offers access to zones unreachable by car: Île aux Cerfs, a sandbar island with no permanent settlement, lies four kilometres off Trou d'Eau Douce and draws crews for its protected anchorages and white-sand curves. Gabriel Island and Flat Island, thirty kilometres north of Grand Baie, are nature reserves closed to motorised vessels but open to sailcraft, their seabird colonies protected under the Wildlife and National Parks Act since 1993.
Catamaran design favours shallow-draft hulls that glide over reef shelves without scraping coral. Twin-hull stability means minimal roll even in open water, and the wide beam creates deck space for lounging, barbecue grills, and swim platforms. Most private catamaran cruise Mauritius tours depart between nine and half-past in the morning, when offshore breezes are lightest and visibility peaks. Full-day charters typically anchor at two or three sites: a snorkelling reef where parrotfish and sergeant majors patrol the coral gardens, a deserted beach for a barbecue lunch of grilled marlin and chicken curry, and a final swim stop before the return leg. Sunset departures from Black River or Tamarin Bay follow the western coast as the light turns amber, the profile of Le Morne Brabant softening against the horizon.
The northern islands route passes Cap Malheureux, where a red-roofed chapel marks the site of a failed British landing in 1810. Gunner's Quoin, a basalt islet shaped like a ship's cannon, rises forty metres from the water and serves as a navigational marker. Flat Island's lighthouse, built in 1867, still operates, its lantern visible twenty-four kilometres out to sea. Île aux Cerfs anchors the eastern itinerary: the island spans one hundred hectares of casuarina groves and tidal flats, its eastern shore exposed to trade winds that sculpt the dunes. Private charters can request mooring at Pointe Maurice or the sheltered bay near the golf course, both offering calm water for paddleboarding and kayaking. The three-island route combines Île aux Cerfs with Île aux Aigrettes and Île de la Passe, the latter a fortified islet where French and British forces clashed in 1810. Crews anchor offshore and tender passengers to the ruins, where stone ramparts and rusted cannon emplacements remain visible beneath the scrub.
