Trou de Madame Coco, Natural cave formation in Anse-Bertrand, Guadeloupe, France.

Trou de Madame Coco is a monumental excavation opening onto a natural underground cavity in the cliff face at the northern tip of Grande-Terre, in the commune of Anse-Bertrand. The Atlantic Ocean carved the marine cave directly into the cliff, and its entrance is almost impossible to reach directly.

The name comes from the legend of Man Coco, a witch who made a pact with the Devil to become stronger than her rival Madame Grands-Fonds. Having broken the pact, she went to sea and the Devil carried her off at the spot called Tou a Man Coco.

The name comes from Man Coco, a witch who, according to the legend, made a pact with the Devil to become stronger than her rival Madame Grands-Fonds. Having broken the pact, she went out to sea and the Devil carried her off to the spot called "Tou a Man Coco". The tale is still told in Anse-Bertrand.

The site sits on the northern coastline near the Porte d'Enfer area and is reachable on foot from local access points. Wear sturdy footwear as the ground around the cave entrance is rocky, uneven, and can be slippery when wet.

The cave is almost impossible to reach directly, so the sounds linked to the legend are reported rather than verified. The name Man Coco belongs to a witch who, the story goes, made a pact with the Devil to surpass her rival Madame Grands-Fonds and was carried off to sea at the spot called Tou a Man Coco.
