Ask the internet for the best beaches in St. Maarten and you get the same roundup every time: Maho for the low-flying planes, Mullet Bay for the postcard sand, Orient for the party, Great Bay for the boardwalk. All lovely. All reachable with a rental car and a bit of patience finding a parking spot.

This is not that list.

We run boats out of Philipsburg most days of the week, and the beaches our guests talk about on the ride home are almost never the ones you can drive to. They are the coves and cays with no road, no parking lot, and sometimes no anything at all, just a strip of sand off the back of a cove that stays quiet because you need a hull to reach it. Here are five of our favorites, plus an honest look at what it takes to get to each one.

The Beaches You Won't Find From a Rental Car

Every spot below has one thing in common: you cannot walk, drive, take a taxi, or catch a bus onto it. Some sit on uninhabited islands a couple of miles offshore. One does not really have a beach at all, just water you will not want to leave. What ties them together is that the crowd thins out the moment the pavement ends.

A quick reality check before we start. Most of these places have no shops, no restrooms, and no shade you did not bring yourself. So pack like it: water, sunscreen, a hat, reef-safe everything, cash for the one or two spots that do sell a rum punch, and reef shoes if your feet are precious. Nobody has ever regretted bringing an extra liter of water to an island with no tap.

Tintamarre: The Uninhabited Nature Reserve Island

Tintamarre is the one first-timers fall for hardest. It is an uninhabited, protected nature-reserve island sitting about two miles (some sources say four kilometers) off Saint Martin's eastern coast, and the only way there is by boat, with shuttle or charter crossings running roughly 15 to 20 minutes.

There are two beaches to know. According to the Saint Martin tourism office, White Bay on the west side is the easiest landing, calm and sheltered, with no umbrellas and no restaurants to break the spell. A short walk south, near where boats moor, is a wilder, more unspoiled stretch that the same source describes as a breeding ground for many fish species. That second beach is where the snorkeling gets interesting.

Come prepared, because there is nothing here. Tintamarre has no facilities, no food, no water, and no built shade, so you carry in your own day. It is a protected Nature Reserve, pets are not allowed, and it is the only nesting site for the endangered Brown Noddy, so the request to respect the marked zones is a real one, not a formality.

The payoff is the water. Tintamarre is a reliable spot for sea turtle sightings, and divers with tanks can explore a shipwreck submerged just off the beach. One heads-up for families: given how secluded it is near the Orient Beach side, you may spot clothing-optional sunbathers on parts of the sand, so pick your landing accordingly.

Prickly Pear Cays: Anguilla's Twin Uninhabited Islets

If Tintamarre is a quiet morning, Prickly Pear is a full day out. The Prickly Pear Cays sit about six miles north of Anguilla's Road Bay and Sandy Ground, and per Wikipedia they split into two uninhabited islets. West Cay is a narrow, rugged three-quarter-mile strip with coral reef and no easy landing. East Cay is the one you actually set foot on: roughly a mile long and a quarter-mile wide, with a long white-sand beach along its north side.

The cays are protected for a reason. Wikipedia lists Prickly Pear as one of Anguilla's marine protected areas, classified as wildlands back in 1980, and an Important Bird Area where red-billed tropicbirds, brown pelicans, boobies, terns, and brown noddies nest. Underneath and around it you will find sea turtles and the little Anguilla Bank anole going about its business.

Here is where Prickly Pear breaks the no-facilities rule in the best way. East Cay has an on-site beach bar and restaurant known for fresh lobster, ribs, mahi mahi, and rum punch. There is no electricity out there, so the drinks run on battery backup, which somehow makes the whole thing taste better. Keep an eye on your plate too, because the resident bananaquits, the little sugarbirds, will land right on your hand for a taste of sugar.

Getting to Anguilla means a border crossing and a proper boat, so it helps to know the logistics ahead of time. We laid it all out in how to get to Prickly Pear in Anguilla, and the easiest way to pair the islet with a stop in Anguilla is to book the Ultimate Anguilla and Prickly Pear Tour.

Pinel Island's Second, Secret Beach

Most people already know Pinel Island, or at least its main bay. Îlet Pinel sits just off Cul-de-Sac on Saint Martin's French side, and the public ferry makes it the most accessible island on this list. According to the Saint Martin tourism office the crossing takes about five minutes, boats run roughly every 30 minutes from around 9:30 or 10am until the last one back at 4:30 or 5pm, and it costs about $10 to $12 round trip, cash only.

That main beach is gorgeous and, by midday, busy. The secret is that almost nobody keeps walking. A second, wilder beach on the island's Atlantic-facing side, reached by a roughly 10-minute walk through coastal heath, sees a fraction of the crowd. It is the best shell-hunting on the island and the place to watch the Atlantic surf show its full force, a completely different mood from the calm bay you just left.

If you want the ferry times, the packing list, and what the walk is actually like, we cover it all in our full guide to Pinel Island.

Petite Clef (Little Key): The Islet Even the Ferry Skips

Just past Pinel is the spot that proves the point of this whole article. Petite Clef, also called Little Key, is a tiny uninhabited islet with no ferry service and no facilities at all. The only way in is by kayak, paddleboard, or private boat, which is exactly why it stays noticeably quieter than Pinel next door.

There is not much to say about the amenities, because there are none. That is the appeal. When Pinel's main bay is shoulder to shoulder, Little Key is the reminder that a short paddle or a boat mooring can buy you an entire islet almost to yourself. Bring everything, take everything back, and enjoy the fact that most visitors never realize it is there.

Creole Rock: The Spot Where the 'Beach' Is Underwater

Creole Rock earns its place on the list even though there is no sand to lie on. Set your expectations right: this is a snorkel site, not a beach chair. It is a rock formation about a mile offshore from Grand Case Bay, and it is reachable only by a short boat ride of roughly five minutes, with boats mooring over a shallow sandy patch around eight feet deep near the rock.

The water does the work here. Creole Rock is part of the wider Saint-Martin Nature Reserve, which covers roughly 30 square kilometers of marine protected area. The reserve's outlying islets, Tintamarre, Pinel and Petite Clef, and Caye Verte, are considered the best places on the island to snorkel with turtles, rays, and reef fish, well ahead of the more developed mainland beaches. Creole Rock is your quick, close-in taste of exactly that.

We wrote up the fish you are likely to see and the best conditions in our post on snorkeling at Creole Rock if you want to know what to look for before you get in.

DIY vs. Charter: What It Actually Takes to Reach Each One

So how do you actually get to these places? It depends on the spot, and we would rather be straight with you than pretend a boat is the only answer.

Pinel Island is the one you can genuinely do on your own. The public ferry from Cul-de-Sac is cheap, frequent, and quick, so if Pinel is your whole plan, a rental car to the dock and a few dollars cash will get you there and back. Everything else on this list is a different story.

Petite Clef, Prickly Pear, Creole Rock, and most of Tintamarre have no scheduled ferry. That means a private boat, or in the case of Little Key, a kayak or paddleboard if you are near Pinel and feeling strong. Tintamarre sits about two miles offshore with a 15 to 20 minute crossing, Creole Rock is about a mile out at roughly five minutes, and Prickly Pear is a six-mile run north of Anguilla that also involves a border crossing. Those are not distances you want to guess your way through in an unfamiliar rental dinghy.

The honest trade-off: renting your own boat gives you total freedom and a real learning curve, from reading the moorings to timing the wind and the customs stops. A guided powerboat or eco tour costs more than a ferry ticket, but it handles the navigation, the gear, the permits, and the local know-how of which cove is calm on which day. Neither is wrong. It comes down to how much of the day you want to spend captaining versus swimming.

Which Boat-Only Beach Fits Your Day?

Still deciding? Here is the short version of how we match guests to spots.

If you are here for snorkeling and wildlife, point yourself at Tintamarre or Creole Rock. Turtles, reef fish, and, for Tintamarre, that shipwreck make them the standouts for time in the water.

If your group wants a real day out with food and a cold drink, Prickly Pear East is the pick. It is the rare boat-only beach with a kitchen and a bar, plus those sugarbirds for entertainment.

If you are after quiet and a shell-hunting stroll, take Pinel's second beach or paddle over to Petite Clef, where the crowds simply do not follow.

The nice thing about a boat is that you do not always have to choose. A single day on the water can string several of these together, which is exactly what our trips are built to do. Our Eco Tour: Sail and Snorkel leans into the reserve's snorkeling, and the Ultimate Anguilla and Prickly Pear Tour is the one to book when Prickly Pear is the goal.

Quick Answers Before You Go

Can you get to Tintamarre without a boat? No. There is no ferry and no bridge, so the only way onto Tintamarre is by boat, with crossings from Saint Martin's east coast running about 15 to 20 minutes. It is a protected nature reserve, so plan to bring your own water, food, and shade.

Is Pinel Island crowded? The main bay gets busy by midday, especially in high season. The trick is the 10-minute walk to the wilder Atlantic-facing beach on the far side, which stays far quieter, or heading to Petite Clef next door, which the ferry skips entirely.

Do you need a guide to snorkel Creole Rock? You do not strictly need one, but Creole Rock is about a mile offshore from Grand Case Bay and reachable only by boat, so you need a way out there and a safe mooring first. A guided trip handles the crossing, the gear, and knowing when conditions are calm.

What should you pack for a boat-only beach day? Water, sunscreen, a hat, and reef-safe products are non-negotiable, since most of these spots have no facilities. Add reef shoes for rocky entries, a little cash for the beach bars at Prickly Pear, and a dry bag for anything you would hate to lose overboard.
