Baie Longue

The longest-beach claim does not survive the only measured source

The French Wikipedia inventory lists a measured length for every beach on both sides of the island. It gives Baie Longue 1,800 metres and Baie Orientale 2,060 metres.

Published length claims for Baie Longue elsewhere range from nearly a kilometre to two miles. That is roughly a threefold spread, which tells you most of these numbers were never measured by anyone and were copied from each other.

The defensible version is narrower and more useful: Baie Longue is the longest undeveloped beach on the island, and the longest beach on the French west coast. Nobody else is going to tell you that, because repeating the superlative is easier.

The calm-water description is guidebook copy, not observation

Search Baie Longue and you get a consistent picture: calm, clear, safe for everyone. Read what visitors actually wrote and the picture inverts. Rough water. Rocks. Difficult entry and exit. Currents strong enough that people stayed chest-deep.

The geography explains why the guidebooks are wrong rather than lying. This is an open, reef-free, southwest-facing shore with deep water close in. It is calm when there is no swell and it is not calm when there is. There is no lifeguard, no flag system and no warning sign to tell you which kind of day you have walked onto.

Nobody has published a measured account of the shorebreak here specifically, so we have left that field empty rather than guess at it. What we can say is that the reviewer language, about rough water, difficult entry and a beach where water access is impossible except in a few places, is exactly consistent with a steep dumping shorebreak on swell days. The much better documented conditions at neighbouring Baie Rouge, which faces the opposite way, include a steep beach face, waves running high up the sand and rocks being moved by the wave.

A page that tells you to look at the water before you get in is more use than a page that repeats calm and clear.

La Samanna, and who gets to use this beach

La Samanna was built between 1971 and 1973 by James and Nicole Frankel, who named it by combining the names of their three daughters, Samantha, Anouk and Nathalie, with the French article. Orient-Express Hotels bought it in 1996 and rebranded it Belmond in 2014, and Belmond is now owned by LVMH. As of 2026 it trades as La Samanna, A Belmond Hotel, having reopened after a villa restyle on 15 November 2024, and it is taking bookings.

Its practical effect on the public beach is about access. The old public route to Baie Longue ran past the hotel and was closed, with forum posters told the hotel did not want traffic near its facilities. The working route since then is to enter from the Baie Rouge side and turn toward Baie Longue once inside. Those reports are 11 to 13 years old, so treat the exact turn as unverified for 2026.

Non-guests were once able to buy in: pre-2017 reviews describe paying about $10 per person for a chair, umbrella, towel, water and pool access. A 2022 visitor wrote that unless you are a guest, they do not want to know you. Whether any arrangement still exists is unknown, so do not plan on it. Food and drink on this bay means La Samanna at resort prices, and a 2019 review reported $18 a drink and $30 for a burger.

One thing sources cannot agree on: which end of the bay La Samanna is on. One places it at the east and Pointe du Canonnier at the west; another reverses them. It matters, because it determines which way you walk to snorkel, and it is trivially resolvable on the ground.

One public access, in the middle, by design

The French Wikipedia inventory records that Baie Longue has exactly one public access point, at the centre of the bay. That is the pattern across Terres Basses: Baie Rouge has one, at the east. Baie aux Prunes has one, at the north.

This is not an accident of terrain. The Terres Basses was laid out under a 1963 planning rule requiring a minimum lot size of one hectare, permitting only residential use with the exception of seasonal rentals and the La Samanna hotel, and banning condominiums and subdivision. That claim comes from a rental agency's blog and is unverified against the underlying document, but it is too specific to be invented and it explains the coastline you find.

The result is a shore where the beach is public but almost all of the land behind it is not, and access is funnelled through single points that the estate controls the road to.

Getting here: roughly 15 to 20 minutes from Marigot southwest through Sandy Ground and Baie Nettlé, or 40 to 50 minutes from Philipsburg up the Dutch side and across, depending on the Simpson Bay bridge. There is no bus. Terres Basses has no public transport of any kind. A taxi can drop you, but there is no business on this beach to call one from, so you would be arranging a return pickup with no guarantee of a phone signal.

One more practical note: the sand is deep and loose enough that walking is hard work, there is no boardwalk, no ramp and no hard surface to the water. This does not work for a wheelchair and is difficult with a walker or a stroller.
