Anse Cosmy beach is located in Trinité, just beyond the village. It is little used during the week but is popular at weekends and during school vacations with local families, who often spend the whole day there.
The beach is furnished with tables and benches and offers plenty of shade.
Beware: at times, this beach is exposed to sargasso from the Atlantic.
To get there, head for the town of Trinité, then after passing through the village, head for Sainte-Marie, continuing on the road that crosses the village and leads to the northern exit of the town. Turn right towards "Résidence Cosmy". You'll then see the beach and be able to park.
