Wedged between two cliffs and shaded by lush vegetation, this exquisite black sand beach is one of Martinique’s most beautiful. This remote and untouched beach is located at the northernmost point of the island, at the foot of La Montagne Pelée volcano. Underwater, you will be likely to spot angelfish, moray eels and butterflyfish swimming between the sea fans bending gracefully in the current.

How to get there?

Anse Couleuvre (meaning “Grass Snake Cove”) is located on the Caribbean side of Martinique, some 40km north of Fort de France (1 hour by car). From Fort de France, take the N2 to Saint-Pierre, then the D10 to Le Prêcheur. Once in Le Prêcheur, follow the road north for a few kilometers. The small road becomes narrow and winding. At the very end of the road, you will find a small parking lot (quickly full during the weekends). Park here and walk to the beach, which can be reached via a 10-minutes’ walk through a tropical forest (well signposted).

Water entrance

Walk north up the beach and get into the water in front of the rocky area, which is the best for snorkeling. This spot is sometimes subject to waves or currents, do not enter the water if the sea is rough.

Exploration

You can basically explore the whole bay, but we advise you to focus on the reef area bordering the north end of the beach (↕3-10ft/1-3m).

The seabed is mostly rocky, and large numbers of multi-colored sea fans and quite a few soft and hard coral species have colonized it. Sponges and sabella complete this underwater garden.

You might see dozens of fish species on the reef, particularly boxfish, needlefish, wrasse, butterflyfish and, with a little luck, the stunning French angelfish. Moray eels, some of them quite friendly, also inhabit the rocky seabed. In the deeper areas, you might spot a sea turtle, although there is much less likelihood of this here than in Anse Dufour and Anse Noire.
