The Seychelles archipelago comprises 115 islands scattered across 1.4 million square kilometres of the Indian Ocean, yet only a handful shelter the endemic Aldabra giant tortoise in the wild. Curieuse Island, a granite outcrop 1.2 kilometres off Praslin's northern coast, is one of them.
Declared a national park in 1979, the 2.9-square-kilometre reserve protects free-roaming tortoise colonies, mangrove forests accessible only by boardwalk, and a coastline where takamaka trees lean over sand the colour of crushed quartz. A Seychelles catamaran cruise serves as the most practical vehicle for reaching these protected zones, bypassing the shallow draught restrictions that ground larger vessels on reef shelves.
The seychelles catamaran cruise tour calendar intensified after the Marine Parks Authority rezoned St. Anne in 1973 as the nation's first marine protected area. Six granite islands—Cerf, Moyenne, Round, Longue, Cachée, and St. Anne itself—form a 14.43-square-kilometre lagoon two nautical miles east of Victoria. The boundaries enclose 150 recorded coral species and seasonal aggregations of hawksbill turtles. Tour operators secure mooring permits in rotating blocks to prevent anchor scarring; the reef substrate here is Pleistocene coralline limestone overlaid with living Acropora and Pocillopora colonies.
St. Pierre, a single-hectare granite monolith rising 12 metres above the Côte d'Or channel, appears on nautical charts as a snorkeling waypoint. The underwater granite boulders descend to 8 metres, forming swim-throughs colonized by sergeant majors, parrotfish, and occasional eagle rays. Surface currents shift with the southeast trades; December through March sees the calmest water. Most catamaran itineraries anchor here mid-route, allowing 40 minutes of free-swim time before the tide turns.
Catamaran hull design—twin keels, shallow draught, wide beam—allows anchoring within 50 metres of shore where monohulls cannot. The platforms accommodate 12 to 18 passengers, with onboard galleys preparing Creole BBQ lunches over charcoal. Skippers trained under the Seychelles Maritime Academy navigate by GPS and local knowledge, adjusting routes for swell height and visibility. Marine Charter Association operators based in Victoria coordinate logistics, holding liability cover and fuel bunkering contracts. The fleet expanded from four vessels in 2015 to eleven in 2026, reflecting demand for guided multi-island access within a single daylight window.
