Baie Rouge, Baie Longue and Baie aux Prunes: the quiet west coast of St Martin
This part of the French side is not where you go for beach clubs, music, menus on the sand or a waiter bringing drinks to your chair. It is where you go when you want space, cliffs, open water, sunset light and beaches that still feel mostly untouched.

Baie Rouge, Baie Longue and Baie aux Prunes sit close to one another around Terres Basses, but they do not give the same day at all. Baie Rouge is the easiest one to reach and the one most visitors know. Baie Longue is wide, elegant and almost empty. Baie aux Prunes feels more raw, especially when the sea is moving.
The big thing to understand before you plan this coastline in 2026: you should arrive self-sufficient. The old Baie Rouge beach bars people still mention in older travel posts are not part of the current beach experience. Do not plan your day around lunch, chairs, toilets or service on the sand.
Which beach should you choose?
If you only have one afternoon, choose Baie Rouge. If you want a long, cinematic walk with almost nobody around, choose Baie Longue. If you like wilder places and do not mind arriving with everything you need, choose Baie aux Prunes.
Baie Rouge
The easiest and most iconic of the three, with reddish sand, dramatic cliffs and beautiful late-day light.
- Best first choice
- Good for photos and sunset
- No reliable services on the beach
Baie Longue
A long, quiet stretch inside Terres Basses, more about space and walking than swimming all day.
- Best for long walks
- Very quiet atmosphere
- Bring absolutely everything
Baie aux Prunes
The rawest option, with a more natural feel and conditions that can change quickly depending on swell.
- Best for wild scenery
- Often very peaceful
- Not ideal for young kids when the sea is rough
Baie Rouge: beautiful, dramatic, and more rustic than old guides suggest
Photo: BookStMartin / Baie RougeBaie Rouge is still one of the most striking beaches on the French side. The name comes from the warm reddish tone of the sand and the cliffs, especially when the sun starts dropping toward the end of the day. It is a beach with presence. You feel it as soon as you arrive.
But Baie Rouge is not the same beach some older travel guides describe. Do not arrive expecting the old beach bars, lunch tables, chair rentals and easy service that people still talk about from years ago. In 2026, the safer and more honest way to present Baie Rouge is as a rustic, largely self-sufficient beach day.
That does not make it less beautiful. It just changes the way you should plan it. Bring your own water, snacks, towel, umbrella if you need shade, and leave nothing visible in the car. Come for a swim if the sea is calm, for a walk along the sand, for the cliffs, for the light, and for that slightly wilder west-coast feeling.
Baie Longue: the beach that feels almost too big for the island
Baie Longue is one of those places that surprises people because it does not feel like the busy St Martin they imagined. The beach is long, open and often very quiet. You can walk for a long time with nothing much happening around you, and that is the whole point.
It sits inside Terres Basses, the residential luxury villa area on the French side. Beach access remains public, but the feeling is different from beaches with villages, restaurants or parking lots right behind the sand. This is a bring-everything beach.
I like Baie Longue most for walking and sunset, not for a heavily planned beach day with children and coolers. The water can be gorgeous, but the beach is exposed, and conditions can vary. On calm days it is dreamy. On rougher days, it is better to admire than to insist on swimming.
Baie aux Prunes: the wildest one, and not always the easiest
Baie aux Prunes, also called Plum Bay, is the most natural and least polished of the three. It can be peaceful and stunning, especially when the sea is calm, but it is not a beach I would sell as universally easy.
There are no facilities, no restaurants, no chairs, no toilets and very little shade. The sea can also change quickly depending on swell. Some days it is lovely for a quiet swim. Other days it is more of a scenic stop, a walk, or a place to watch the waves rather than get in.
That honesty matters. Baie aux Prunes is beautiful because it has not been turned into a product. But that also means you need to respect the conditions, bring what you need, and avoid treating it like a serviced beach.
How to get there
You need a car for this coastline. Taxis do not make much sense here because the beaches are spread out, there is no real service infrastructure on the sand, and you may want to leave earlier or later depending on the conditions.
From Marigot or Nettle Bay, drive west toward Terres Basses. Baie Rouge is the first and easiest beach to add to your day. For Baie Longue and Baie aux Prunes, you continue into the Terres Basses area and follow the beach access roads.
Road and parking conditions can change after rain or heavy use. Drive slowly, avoid leaving valuables in the car, and do not assume the parking areas will feel as organized as Orient Bay or Grand Case.
Read the car rental guide →What to bring now that there are no beach bars on Baie Rouge
This is the section that needs to be clear, because too many older pages still create the wrong expectation. Do not rely on Baie Rouge for food, drinks, beach chairs, umbrellas or toilets. The current beach experience is much more natural and self-sufficient.
Bring water, snacks or a picnic, sunscreen, a hat, towels, and your own shade if you do not like full sun. For Baie Rouge, snorkeling gear can be worth packing when the water is calm and clear. For Baie Longue and Baie aux Prunes, I would prioritize water, shade and common sense over anything else.
Where to stay near Baie Rouge and Terres Basses
This part of the island is more villa territory than hotel territory. Around Terres Basses, the experience is usually about privacy, space, pools, sea views and easy access to several beaches by car.
If you want restaurants within walking distance, stay in Grand Case or Orient Bay instead. If you want quiet luxury and a more private base, Terres Basses and the area around Baie Rouge can make a lot of sense.
