The inner granitic islands of Seychelles sit within a twelve-nautical-mile arc of Mahé's northeast coast, separated by channels shallow enough to snorkel and deep enough for twin-hulled vessels to cross without pitching.
Catamaran charter fleets operating from Victoria harbor have traced these routes since the mid-1990s, when the St. Anne Marine Park was formally gazetted and Curieuse Island reopened to day visitors after decades as a leper colony turned giant tortoise sanctuary. The vessels themselves—purpose-built catamarans with trampolines stretched between hulls and shallow drafts allowing anchorage within twenty meters of shore—now carry between twelve and forty passengers per departure, departing daily at 08:00 and returning by 17:00.
A Seychelles catamaran day trip connects three to four islands in a single itinerary, structured around tidal windows and marine park mooring schedules. The St. Anne Marine Park route threads through six low-lying islands—Cerf, Moyenne, Round, Long, Cachée, and St. Anne itself—each ringed by coral gardens in three to five meters of water. Curieuse Island excursions navigate the narrower Cousin Channel to reach a crimson-granite coastline where Aldabra tortoises graze beneath takamaka trees and ranger-led trails loop through mangrove boardwalks. Sister, Coco, and Félicité represent the offshore tier: open-water crossings of forty minutes, steeper drop-offs, and visibility that can exceed thirty meters when the southeast monsoon settles in July.
Onboard protocols reflect marine park conservation rules enacted in 2018. Non-resident passengers pay a 300-SCR conservation fee before boarding. Snorkeling gear is distributed after the safety briefing, and anchoring zones are GPS-marked to prevent coral damage. Lunch is served mid-voyage—grilled fish, chicken, breadfruit salad, rice—either at a beachside picnic site or under the catamaran's awning if swells prohibit landing. Alcohol service is discretionary and operator-dependent. Return crossings time themselves to the afternoon thermal wind that builds between 14:00 and 16:00, allowing sails to be raised for the final leg into Victoria's inner harbor.
The Seychelles Tourism Board tracks approximately forty thousand catamaran day-trip passengers annually, the majority concentrated between April and October when the northwest monsoon eases and sea conditions stabilize. Charter operators hold Marine Charter Association membership and employ skippers certified under the Seychelles Maritime Safety Administration. Vessels undergo annual hull inspections and carry satellite phones, VHF radios, and life rafts rated for offshore passage. Passenger insurance is compulsory under Seychelles law.
