Simpson Bay Lagoon, St. Maarten: The Water in the Middle of the Island
One of the Caribbean's largest lagoons, shared by two countries and full of boats.
Why Go
Simpson Bay Lagoon is the flat sheet of water at the centre of the island, big enough to see from every hill and shallow enough to have been a salt pond before it was a harbour. Two countries share it, two lifting bridges let boats in and out, and the shore around it holds the marinas, chandlers and boatyards that make St. Maarten the yachting capital of this part of the Caribbean. It is not a beach and not a neighbourhood — it is the working water everything else is arranged around, and it is where you go to get on a boat.
The Experience
The lagoon is ringed rather than fronted. On the Dutch side the marinas and the bridge at Simpson Bay open onto the sea; on the French side the Sandy Ground bridge does the same into Marigot Bay. In between are docks, brokers, riggers, sailmakers and the bars that serve them, and megayachts sitting in water so still it mirrors them. The rhythm is set by the bridge openings: traffic on the road stops, a queue of masts goes through, and everything resumes. Through hurricane season a large share of the region's yachts come inside to sit it out, which is the clearest measure of how sheltered this water is. It is a working place with visitors welcome rather than a visitor place, and that is why the eating and drinking around it is better value than the beachfront. Once you notice the lagoon you start seeing how the island is organised around it.
What to Try
Get on the water — that is what the lagoon is for. Random Wind, Papa Smurf Charters, Xisle Boat Charters, Pyratz Boat Charters, TaylorMade Charters and Renegades all run day sails and catamaran trips from here, out to Anguilla, Tintamarre and the offshore cays. The Scuba Shop covers the diving side. Eat where the boat crews eat: Zee Best Breakfast & Lunch is the morning institution, the Dinghy Dock Sailors Bar and the Soggy Dollar Bar are the lagoon-side drinks, and Melange Grill, Sebastiano SXM, Secret Seafood House and White Swan cover the evenings. Don Pero's The Dessert Spot handles the rest. Princess Casino at Port de Plaisance is the late option. For shopping, Penha and Connoisseur Duty Free and Goldfinger Jewelry are on this stretch, with Carrefour Market for a proper supermarket run.
Insider Tip
Learn the bridge times on day one and plan around them. Both lifting bridges close the only road while they are open, and being on the wrong side of one with a flight to catch is the classic mistake here — locals simply know the schedule and route around it. Beyond that, the lagoon shore is where to eat if you have been paying beachfront prices all week: the same kitchens serve the boat crews who live here year-round, and the bill reflects that.
The Practical Stuff
The lagoon sits between Simpson Bay, Cole Bay and the French border, five to ten minutes from Princess Juliana airport and fifteen to twenty from Philipsburg. There is no single address for it — you reach a specific marina, bar or dock rather than the lagoon itself, so get the name of where you are going rather than aiming at the water. A car is useful; parking around the marinas is free and easy compared with the beaches. The Dutch–French border runs across the lagoon and is open with no formalities. Bridge openings happen several times a day on a published schedule and stop road traffic each time. Hurricane season runs roughly June to November, which is exactly when the lagoon fills with boats seeking shelter.
Common Questions
What is Simpson Bay Lagoon?
One of the largest lagoons in the Caribbean, in the middle of St. Maarten and shared between the Dutch and French sides. It is the island's yachting centre, ringed by marinas, boatyards and the businesses that serve them.
When do the Simpson Bay bridges open?
Several times a day on a published schedule, at both the Simpson Bay and Sandy Ground bridges. Each opening closes the road entirely, so check the current times locally and plan airport runs around them.
Where do boat trips leave from in St. Maarten?
Largely from the marinas on this lagoon. Day sails and catamaran trips to Anguilla, Tintamarre and the offshore cays go out through the bridges from here.
Is there a beach on Simpson Bay Lagoon?
No — it is enclosed water, not coastline. Simpson Bay Beach and Kim Sha are on the sea side of the same strip, a few minutes away, and Mullet Bay is ten minutes west.
Why do yachts shelter in the lagoon?
It is almost entirely enclosed and shallow, which makes it one of the best hurricane refuges in the region. A large share of the area's yachts come inside for the season, roughly June to November.
Is the lagoon Dutch or French?
Both — the border runs across the water. It is open with no formalities, and boats and vehicles cross it without checks, though currency and phone roaming can change from one shore to the other.
