The Six Islands of the Sainte Anne Marine Park

The Sainte Anne Marine Park has six islands: Ste Anne, Ile Moyenne, Ile Ronde (Round Island), Ile Longue (Long Island), Ile Cachee and Ile aux Cerfs (Cerf Island), in the list of the Seychelles Parks and Gardens Authority (SPGA), which runs the St Anne Marine Park. Two of them hold hotels with restricted access and one is a nature reserve, so a day in the park lands you on Moyenne, Cerf or the beach and sandbank of Long Island, depending on the boat. Footprint Charter’s Mahe Island: St. Anne Marine Park Semiprivate Snorkeling Trip, from $177 per adult, two adults minimum (checked November 2026), lands on Long Island’s beach and sandbank; Vision Voyages DMC's reef safari, from $160 per adult (checked November 2026), lands on Moyenne.

The calendar above is Footprint Charter’s snorkelling trip, with 86 reviews (checked November 2026).

Ste Anne

Ste Anne, dominated by a hill rising to 246 m, was the site of the first French settlement in 1770, and in the Second World War a base for the Royal Marines who defended Victoria; remnants of their cannons are still there. It is now occupied by a five-star hotel and access is restricted. SPGA calls it one of the most important nesting sites for hawksbill turtles in the granitic islands, and its nesting beaches, Grand Anse, Gran Manon, Petit Manon and Anse Cimitiere, are closed to visitors. The boat days pass it.

Cerf Island

The second-largest island, named after the frigate Le Cerf, whose commander took possession of the Seychelles for the King of France in 1756. Its 290 acres are divided into private plots, and SPGA describes shallow waters and reefs for snorkelling, swimming and scuba diving. Several boat days stop here for lunch: Mae Guide's glass-bottom day lands for a Creole BBQ, SEY AMA's glass-bottom boat for a BBQ buffet and its giant tortoises, and Footprint Charter's private full day for a Creole lunch on the beach.

Moyenne

Moyenne is privately owned and, in SPGA’s words, a national park of its own, just under half a kilometre long, with a 30-minute trail among giant tortoises. It is the island the full-day catamarans land on: Vision Voyages DMC's reef safari and Creole Travel Services' cruise both include a visit. Its landing fee is the island’s own and is not on SPGA’s ticket page.

Long Island and Round Island

Long Island (Ile Longue) sits between islands that SPGA calls a great favourite with visitors. The boat days use its beach and the sandbank between it and Round Island: Footprint Charter’s snorkelling trip and its private half day land on Long Island’s beach, and SEY AMA and Mae Guide stop at the sandbank.

Round Island (Ile Ronde) lies close to Moyenne. It is occupied by a hotel and access is restricted.

Ile Cachee

An uninhabited islet of five acres, classed as a nature reserve and an important breeding site for noddies. It has a dive site that can be used only during the northwest monsoon. Mae Guide's afternoon snorkel stop is around Cerf Island and Ile Cachee.
