Go for it
Anse à l'Âne stretches along the northern shore of Les Trois-Îlets, on the Caribbean coast of Martinique, looking straight across the water at Fort-de-France. Pale sand, a gentle entry into the sea, and a jetty where the ferry from the main town ties up.

What to know about this beach
Anse à l'Âne sits on the leeward flank of the island. Sargassum rafts crossing the Atlantic travel with the easterly trade winds and reach the windward coast first, around Le Robert, Le François and the Sainte-Anne peninsula. Getting to this shore means rounding one tip of Martinique and drifting back up with the coastal current, which happens far less frequently.
Facing north adds a second layer of shelter: the cove looks into the Baie de Fort-de-France rather than the open sea, and that broad, partly enclosed basin keeps the easterly swell from arriving head-on. When weed does appear, it has usually been shifted around inside the bay instead of landing fresh from offshore, and quantities stay modest. The slope is gentle here, so a thin patch can sit at the waterline for a while before the current scatters it.
Frequently asked questions
Does Anse à l'Âne get much sargassum?
Far less than the Atlantic side of Martinique. It lies on the sheltered west coast and opens into the Baie de Fort-de-France, so rafts driven by the trade winds have two barriers to clear before reaching the sand.
How do I check the beach before crossing from Fort-de-France?
Open the FanGass map for the zone. Anse à l'Âne is given a fresh 0 to 5 rating every morning, describing what was seen on the shore, so you can check it before boarding the ferry.
When is sargassum most likely at this beach?
Caribbean arrivals generally run from spring into late summer, with peaks that vary a great deal year to year. On this sheltered shore the season tends to mean short, light episodes rather than lasting deposits.
Which nearby beaches can I check instead?
Stay in the south-west Caribbean zone: Anse Mitan and Pointe du Bout are minutes away in Les Trois-Îlets, and the Anses-d'Arlet coves lie further south. The map shows their ratings side by side.
