Discover Grand Cul-de-sac Marin

Hop aboard and explore the Grand-Cul-de-Sac-Marin.  This excursion will take you to the Ilet Caret, a small, charming confetti of coral that is doomed to disappear from natural erosion. You can either go snorkeling or do farniente at your convenience. You will then head to the 23-kilometer-long coral located in the marine reserve. Your ecotourism guide will explain everything about the complex ecosystem of this immense, fragile lagoon, a part of which is also a nature reserve, in a fun and educational way during the trip and all day long. 

Once you have arrived at the coral reef, your guide will take you to the heart of it for a snorkeling dive so you can watch the wildlife and the corals.

After you will set off to the Fajou reserve. You will get to have a dip there and discover the red and black mangroves, which set the surrounding mangrove apart from the others, during the guided tour. You will also get to watch the location's wildlife, oysters, crabs, sea cucumbers, small lemon sharks (nursery site), turtles, starfish, and take pictures of pelicans that are hunting. You can also rest on a lovely little preserved beach. It will then be time to have your aperitif followed by a creole meal served on the boat, to keep the nature intact.

Your guide will offer to take you to the mangrove to discover it and understand how the mangroves adapt so well to their particularly hostile saline environment. We will then stop at the Carénage islets, which are entirely made of red mangroves, with their aerial roots anchored in the mud and at the salty water, and then go to ilet Blanc, the access to which is forbidden for a part of the year while the terns breed. There is also a planned stop at Ilet aux oiseaux so you can watch the egrets, herons, frigatebirds, and pelicans.
