Mangrove roots create a quiet and protected area for fishes, crabs, oysters, lobsters and shrimps. The forest is also a guard zone for reptiles, mammals and birds and protects the coast from erosion. If you like ecotourism activities, interesting activities are offered to visitors (not in low season), such as the construction of houses for fish and the planting of sea grasses.
Inside the mangroves there is a restaurant on stilts very appreciable for its setting and its cuisine (seafood in particular)
