The beach really does disappear, and that is two different things
Almost every listicle says Cupecoy vanishes at high tide. That is half right, and the missing half is more useful.
The tide part is real. At high water the usable sand in the coves shrinks toward nothing and the cave section becomes unreachable. A June 2025 visitor reported being unable to get to the caves because of the tide. Worth knowing the scale though: Sint Maarten's tidal range is small, on the order of tens of centimetres, so a tide effect this dramatic on a beach this steep is really the tide plus whatever swell is running that week.
The part that gets missed is seasonal sand transport. One local guide describes the sand varying week to week, with some weeks offering metres of beach and others almost none, driven by wave patterns. That is ordinary offshore and onshore sand movement: winter north swell pulls sand out into bars, calmer summer conditions push it back. So you can arrive at dead low tide in February and still find very little beach.
The practical rule: check a tide table for Philipsburg or Simpson Bay, aim for the two hours either side of low water, and accept that in a north-swell winter week the coves may be rock and water whatever the tide is doing.
Clothing optional, tolerated, and not actually legal
Cupecoy is the Dutch side's de facto nude beach and every guide says so. What almost none of them say is that the Dutch side has no legal nude beach at all.
The clearest statement of this comes from a naturist site, which has no reason to discourage anyone: Orient Beach is the only official nude beach, and the others are places where the practice is known to be tolerated. On the TripAdvisor forum a destination expert puts it as clothing optional but, being on the Dutch side, not really legal, and a resident replies that it has been clothing optional for decades with no issues. Both are right. They are describing the statutory position and the enforcement reality, which are different things.
In practice: nudity is concentrated on the western stretch toward and past Dany's Beach Bar, there is a warning sign in English at the entrance, and it has been that way since at least the 1980s. Naturists are directed to the roped-off parking section past Dany's, where you lower the rope, drive through and put it back. It carries no practical risk. It is a custom rather than a right.
What we could not establish: which article of the Sint Maarten criminal code would apply, and whether police have ever acted on it at Cupecoy. We looked and found nothing.
Two ways down, and they are not interchangeable
The eastern access is a path from the sandbox lot across from the former Blue Mall, leading to a carved stone staircase cut into the cliff. The western access is at Dany's Beach Bar, where you turn down and drive to a roped-off parking section closer to the clothing-optional stretch. The western one is the flatter of the two and the only realistic option for anyone with limited mobility, and even that is soft sand. Between coves you scramble over rock. This is not a wheelchair beach in any meaningful sense, whatever the aggregator sites tick.
The staircase has a small history. A long-time visitor filed a question on TripAdvisor asking whether the steps on the eastern side were still there, dating their memory to the 1980s. Reviews from 2023 onward answer it: a June 2023 visitor mentions going down steps to reach the water, and an August 2024 visitor says flatly that access has improved with the addition of steps. So: historic steps, a period when they were gone or degraded and people walked the long way round to Dany's, and a carved stone staircase in place again by 2023 or 2024.
Who built or rebuilt it, when, and whether anyone maintains it, we could not find out. Also note that the navigational landmark for the eastern lot is described as the former Blue Mall, and a landmark described as former is a landmark worth checking the current name of before you follow directions.
The cliffs are the appeal and the hazard, and one popular claim we will not repeat
The cliffs are soft sedimentary rock that the sea has undercut into caves, overhangs and hollow inlets. That is the entire visual appeal of Cupecoy. It is also the hazard: undercut soft rock above a beach where people sit for shade is a rockfall setup, and the caves everyone photographs are by definition the parts that have already failed. Do not sit directly under an overhang and do not climb the cliff edges above the coves. That advice stands on the geology alone.
Sources cannot even agree what the rock is. Some call it golden sandstone, one visitor described steep rosy limestone. Both terms are in circulation and a geologist would have to settle it. Sandstone is the common local term.
There is a widely repeated claim that people have been injured by cliff collapse here. We could not verify a single documented incident. We searched the St. Martin News Network archive, the Nature Foundation archive and four pages of visitor reviews spanning 2017 to 2026, and found nothing. The Daily Herald archive blocks automated searching and is the likeliest place such a report would live, so someone needs to check it. Until then we are not going to print an injury claim we cannot source, and neither should anyone else.
The beach is public. Getting to it crosses somebody's building site
Cupecoy is the most heavily developed stretch of the Dutch side outside Philipsburg, and the pressure is currently rising.
In December 2009 the Sint Maarten PRIDE Foundation reported that a developer had illegally built a wall on Cupecoy beach, covering natural rock formations, and asked for it to be demolished at the developer's expense. Whether it ever came down, we could not establish. In 2024 and 2025 a 15-storey condo hotel called The West Vue went up on the former Summit Resort parking lot, 121 units plus restaurants and a spa, on a building permit issued in February 2024. Residents protested in February 2025 over lost vehicle access, construction traffic and worker barracks built close to homes, with access negotiations unresolved despite court-ordered mediation.
The legal backdrop matters. The St. Maarten Beach Policy of August 1994 says beaches must be openly accessible to the public, with wide access free from physical and mental barriers, and that government will not permit construction on beaches absent special circumstances. In the Mullet Bay litigation the government argued that all St. Maarten beaches form part of the public domain, and in July 2026 the court confirmed Mullet Bay Beach itself is public while the land behind it is privately owned, finding that the exact boundary had never been clearly established.
What that means for you at Cupecoy in 2026: the beach is public and you are entitled to be on it. The friction is not a gate. It is that every route to the sand crosses land somebody is building on, and the parking is informal dirt at the edge of it. Whether any access route is currently obstructed by the construction is the one thing we would most want checked before a visit.
