Grand Cul-de-Sac Marin Excursions

An immense nature reserve

The Grand Cul-de-Sac Marin is a vast bay in Guadeloupe, located between the northern coast of Basse-Terre and the western coast of Grande-Terre. It is enclosed offshore by coral reefs.

This large area includes several islands and islets, and covers about 15,000 hectares. The bay is protected as a nature reserve.


Recognized as a Ramsar Site

A Ramsar Site is a wetland of international importance, recognized for its exceptional biodiversity (waterbirds, rare habitats) and protected under the Ramsar Convention. These sites (marshes, peatlands, lakes) are subject to sustainable management aimed at preserving water resources and ecosystems, often in connection with other conservation designations.


Boat Tours in the Grand Cul-de-Sac Marin

Most excursions depart from Sainte-Rose.

Types of excursions

Thrill excursions with a powerful boat, sometimes with loud music: it’s not a bad idea, but make sure you choose an operator who is respectful of the nature reserve.

Educational excursions designed to help you understand how this beautiful reserve works and to learn more about its fauna and flora. Here as well, take time to check reviews from previous visitors to avoid inexperienced or unreliable guides. In this category, there are also kayak tours, which allow you to reach places boats cannot access. They are very enjoyable, although you will only discover a small part of the reserve.

Overview of a Half-Day Tour

Several excursions are available to visitors. For example, with Richard from Alizés Adventure, you can explore the heart of the mangrove, Îlet la Biche, the coral reef, Îlet aux Oiseaux, and Îlet Blanc, including stops for snorkeling.
