Petites Cayes

French side
  • Secluded
  • Hike to reach

Pale, with rocky, coral-rubble margins on the approach and at either end. None at the beach. You park at a trailhead: a small informal gravel area by the water treatment plant above Anse Marcel, or roadside at Grandes Cayes. A hike to reach. No fee.

Getting in
Long walk
Parking
No parking. There is no parking at the beach because there is no road to it. The western trailhead has an informal gravel lot that mainly serves the water treatment plant, described as small, above the Anse Marcel resort area. The eastern trailhead at Grandes Cayes is informal roadside or track parking with no marked lot. Neither is attended, so leave nothing in the car. There is no bus to either trailhead, and a taxi can drop you but will not wait out a two-hour hike unless you arrange and pay for it. One open question: whether the water treatment plant lot at the Anse Marcel end is still open to hikers now that the main resort there has closed.

Safety
Heat and dehydration are the realistic emergency here, not the sea. Carry at least 1.5 to 2 litres of water each, wear closed shoes with grip, and start early. One specific trail warning worth repeating: cactus grows right at the path edge, so do not grab a plant for balance. Rescue access is poor. No vehicle can reach the beach, and any evacuation is on foot back over the trail or by boat if the weather allows, which is the strongest argument for walking with a companion. In the water, a French guide is explicit that northeast wind or swell brings strong waves and currents and that this is dangerous for children and inexperienced swimmers, and a first-hand account found surf strong enough to make swimming dangerous on the day of the visit. The beach faces roughly north to northeast, fully open to Atlantic swell with no protecting reef, and entry and exit are complicated by rocks and boulders, so a wave that would be harmless on open sand can put you into rock. Carry a charged phone, though whether coverage reaches the beach is unverified.

The story

Petites Cayes is an empty sand beach inside the Réserve Naturelle on the wild north coast, and the only way to it is the Sentier des Froussards, on foot, from Anse Marcel or from Grandes Cayes. There is no road, no track, no facility and nobody there. The trail name translates roughly as the cowards' trail, which is a good story, though not one anybody has sourced properly.

Checked: August 2026 · Reported

The walk times online do not agree, because people measure different things

This is a genuine traveller trap, so here are all the figures.

The Réserve Naturelle, the primary source, gives 4.5 km and 2.5 hours for the full Anse Marcel to Grandes Cayes traverse, which passes Petites Cayes in the middle. A French hiking database plots a loop at 11.33 km, 3 hours 55, with 226 m of climbing. Two French guides quote 1.5 to 2 hours round trip to the beach and back. A first-hand account from the Anse Marcel side gives about 50 minutes to the viewpoint plus about 20 more down to the beach, so roughly 2 hours 20 round trip with stops. A local guide says about an hour each way.

The honest answer: budget 2 to 2.5 hours round trip from Anse Marcel to the beach and back, and about 4 hours if you traverse the whole trail to Grandes Cayes and then have to get back to your car.

The route involves rocky path, tree roots, boulder scrambling near the beach and a steep initial road climb from the Anse Marcel side. It is not accessible in any sense: no wheelchair, no stroller, and not workable with significant mobility limits.

Two of the guides describing this beach are the same guide

Two sites publish near-identical Petites Cayes content: the same access framing, the same 1.5 to 2 hour round trip, the same list of what is absent, the same audience line, the same charged-phone advice.

Treat them as one source, not two. That matters more than it sounds, because if you strip them out, the pool of genuinely independent English-language reporting on this beach is very small: the reserve's own trail page, one or two first-hand trip reports, and a trail app's reviews.

It is also why we are being careful about what this page asserts. There is not much here that more than one person has actually written down.

It is inside a protected reserve, and that changes what you can do

The Réserve Naturelle Nationale de Saint-Martin covers this coastline, and the rules that matter to a hiker are simple: nothing is collected, nothing is left behind.

Camping is authorised only in designated areas on Tintamarre and Pinel, with a form filed at least three days ahead, which excludes Petites Cayes entirely. Reserve infractions are reported to carry fines up to €1,500, though that figure rests on a single secondary source.

This is not a beach where you set up a cooler and a speaker. It is a beach where you carry water in and rubbish out.

The reserve now lists the Sentier des Froussards as one of its four active discovery trails, running through what it calls the island's last intact coastal dry forest. Hurricane Irma tore up that forest in September 2017, and a 2020 review flagged trail maintenance problems and recommended starting from Anse Marcel rather than the original debris-strewn approach. The reserve listing implies the trail has been re-established, but no post-2020 official maintenance statement exists. So: signposted and in use, and do not expect a groomed path.

The name of the trail is the story, and nobody has sourced it

Sentier des Froussards translates roughly as the cowards' trail. The account you will hear locally is that the name comes from this coast being used by people who did not want to be seen: the northern shore of St. Martin is the closest French land to Anguilla, and this stretch has a long association with smuggling and quiet crossings.

We could not find a primary historical source for the origin of the name. The translation is literal and the smuggling association is widely repeated, and that is as far as the evidence goes. It is a good story and it is not established fact, and those are different things.

What is not in doubt is the beach. The reserve's own trail material calls it the desert beach on the route, and a hiking account calls it a magnificent white sand beach. Visitors describe it as extremely serene and quiet with minimal foot traffic. Expect to see nobody, or a handful of other walkers. There is no cruise excursion that walks people two hours over a ridge, so ship days do not touch this place.

One thing to plan around: sargassum. This is a north-to-northeast-facing Atlantic-exposed beach on the windward side, which is the aspect that gets hit, roughly April to August. Because nobody clears this beach, what lands here stays until the sea takes it back.

Common questions

Quick fact

Can you drive to Petites Cayes?

No. There is no road to the beach. It is reachable only on foot via the Sentier des Froussards, from Anse Marcel at the western end or from Grandes Cayes at the eastern end. Boat landing is possible in calm conditions but there is no dock.

Quick fact

How long is the hike to Petites Cayes?

Budget 2 to 2.5 hours round trip from Anse Marcel with stops. The Réserve Naturelle gives 4.5 km and 2.5 hours for the full one-way traverse from Anse Marcel to Grandes Cayes, which passes Petites Cayes in the middle. Published times vary widely because sources measure different routes.

Quick fact

Are there any facilities at Petites Cayes?

None at all. No restrooms, no shade structures, no food, no water, no lifeguard, no bins. Carry your own water and carry out your rubbish. The nearest food is at Anse Marcel or Cul-de-Sac village.

Quick fact

Is it safe to swim at Petites Cayes?

Only on calm days, and only if you are a confident swimmer. Northeast wind or swell brings strong waves and currents, entry is complicated by rocks and boulders, and there is nobody to rescue you. A French guide is explicit that it is not for children.

Quick fact

What should I bring to Petites Cayes?

Closed shoes with grip, at least 1.5 to 2 litres of water per person, sun protection, a hat, a charged phone, and a bag for your rubbish. Start before 8am. There is no shade on the sand and no shop anywhere on the route.
