The Mangrove: An Indispensable Green Lung
The mangrove, which stretches for miles along the coast, plays an essential role in protecting the coastline and preserving numerous marine and terrestrial species. It is home to red, black and white mangroves, whose roots form a perfect habitat for juvenile fish, crustaceans and migratory birds.

- Herons and egrets perched on the branches.
- Crabs and hermit crabs along the mangrove roots.
- Schools of fish shelter in this natural labyrinth.
Coral Reefs: A Dazzling Underwater World
With a coral reef more than 25 km long, the Grand Cul-de-Sac Marin is one of the most impressive diving and snorkeling sites in Guadeloupe. The coral reefs are home to a variety of fauna, from multicolored tropical fish to majestic rays and sea turtles.
