Overview
This one-hour semi-submarine tour departs from Eden Island and travels to designated viewing spots within Sainte Anne Marine National Park near Mahé.

No special clothing is required, and the tour is suitable for all ages. Passengers remain dry throughout the trip while seeing the underwater environment. The boat first leaves Eden Island, which opened in 2012 and features a marina, luxury hotel, restaurants, bars, and a shopping mall.

Other islands visible include Cerf Island, noted for reefs and snorkeling spots; Moyenne Island, a private island with settler ruins and pirate graves; Round Island, a rocky islet with diverse marine life such as green sea turtles and eagle rays; and Ile Cachée, a small nature reserve island thought to have pirate treasure and seabird nesting areas.

Sainte Anne Island is the largest of the eight islands in Sainte Anne Marine National Park, featuring sandy beaches. It was the location of the first French settlement in 1770, established despite surrounding crocodile-infested swamps. The island is dominated by a hill reaching 246m and covered in dense tropical vegetation. During World War II, it served as a Royal Marines base defending Victoria, the capital of Seychelles. In the early 19th century, it was also a center for whaling activity in the Seychelles.

A small private island under 500 meters long, Moyenne features tropical gardens with remains of early settler homes, pirate graves, and a small thatched chapel.
Round Island
This small rocky island hosts reefs and lagoons that support green sea turtles, butterfly fish, eagle rays, moray eels, and other marine species along its coral edges.
