St. Martin, Marina Fort Louis

Tucked into the turquoise bay of Marigot beneath the historic Fort Louis, this is the main marina on the French side of St. Martin, naturally sheltered from ocean swell and currents. You get 150 berths at 3.6m depth, fuel bunkering, and customs clearance assistance — all steps from the colorful French Caribbean town with its open-air market, cafés, and boutiques.
