Martinique blends French-Caribbean culture with serious underwater variety. Warm water around 27°C to 29°C and year round trade winds keep conditions comfortable, while the leeward coast offers calm reefs, dramatic pinnacles like Rocher du Diamant and historic wrecks under Mount Pelee at Saint-Pierre. Non divers get rainforest hikes, golden beaches and rum distilleries within short drives of the main dive hubs at Anses d'Arlet, Trois Ilets, Le Marin and Fort de France.
Why come to Martinique
Martinique is a full service French department with reliable health care, good roads and European style shops, but it still feels distinctly Caribbean in its music, food and village life. Divers base themselves on the Caribbean west coast, where steep green hills drop into bays lined with small fishing boats and moored dive skiffs. Offshore, volcanic rocks and lava flows form walls, swim throughs and sheltered gardens that suit everyone from new Open Water divers to wreck and deep enthusiasts.
Underwater landscape
- South coast: around Anses d'Arlet, Rocher du Diamant and Sainte Luce you get classic Caribbean reef diving, pinnacles, arches and turtle filled bays with depths from 5 m to beyond 30 m.
- North west: the Bay of Saint-Pierre is scattered with steel and wooden wrecks sunk by the 1902 eruption of Mount Pelee, plus offshore seamounts like La Perle with schooling jacks and pelagics.
- Atlantic side: fewer dive sites but big Atlantic swell, surf breaks and windy lagoons give options for kitesurfing and downwind SUP sessions when you want a break from tanks.
Who Martinique suits
- Mixed groups where some want serious diving and others prefer beaches, hiking or food.
- Photographers and macro lovers who enjoy rich reef scenes, wreck structures and abundant turtles rather than sharks.
- Intermediate and advanced divers who want a couple of deep or current swept signature dives in a week, but also relaxed reef days.
How long to stay
- Long weekend: base in Anses d'Arlet or Trois Ilets for 4 to 6 reef and Diamond Rock dives, plus one hike or rum distillery.
- One week: split time between the south (Anses d'Arlet or Sainte Luce) and the north (Saint-Pierre) to add wrecks and La Perle, with a day on the Caravelle Peninsula.
- Ten days or more: add more topside exploration, freedive coaching or a side trip by ferry to Dominica or Guadeloupe.
