Simpson Bay Lagoon

Simpson Bay Lagoon is the largest natural lagoon in the Caribbean, a body of sheltered water roughly eight kilometres long that physically separates the Dutch side of Sint Maarten from the French Collectivité on the western shore, and crossing its single drawbridge at Simpson Bay is one of the most mundane yet symbolically charged moments in a visit to this island, where the act of crossing from one national jurisdiction to another is accomplished without a passport check and sometimes without the visitor even registering that they have changed countries.

The lagoon has been transformed over recent decades from a working harbour for local fishing boats into the Caribbean's primary superyacht facility, with berths for vessels up to 90 metres drawing a wealthy international clientele who anchor in the sheltered water and come ashore to a strip of restaurants, provisioning shops and bars that has developed along the Dutch side of the shoreline, creating a marine infrastructure that is proportionally larger than anything else on the island.

The social life of the lagoon centres on the drawbridge itself and the immediate waterfront, where the bridge opening and closing is as much a local spectacle as the runway landings at Maho, drawing crowds of both visitors and locals who gather to watch the superyachts and sailing vessels pass through the narrow channel and to observe the sometimes tense negotiations between the bridge operator and the drivers queued on either side.

The water of the lagoon is calm, shallow in places and popular for paddleboarding, kayaking and small-boat sailing, with several local operators renting equipment and running lessons from beach-side stands on the Dutch shore, making this one of the most accessible water-sports environments on the island for non-specialist visitors who may not want the stronger surf conditions found on the Atlantic coast beaches.

From the water the view in both directions is distinctive: toward the east the green hills of Sint Maarten rising above the shoreline development, and toward the west the lower and more uniformly residential profile of the French side with its characteristic low-rise Caribbean architecture, a contrast in development density that is immediately visible from any boat on the lagoon and which illustrates the different planning approaches of the two administrations.

The lagoon is also ecologically significant as a nursery area for reef fish and a feeding ground for coastal bird species, and several local conservation groups monitor water quality and mangrove health in the shallower southern sections of the lagoon, though the superyacht traffic has put increasing pressure on the ecosystem in recent years and the balance between the economic value of the yacht harbour and the ecological value of the lagoon is an ongoing local debate.

The Caribbean's largest natural lagoon and its premier superyacht harbour, with a vibrant waterfront social scene.

A unique island-crossing experience: the Simpson Bay drawbridge is the only road connection between the Dutch and French sides of Sint Maarten.

Calm sheltered water suitable for paddleboarding, kayaking and small-boat sailing, with equipment rentals available on the shore.
