St. Croix vs St. Martin

If you'd like to skip the passport and settle into one house on a roomy island with great diving, come to St. Croix. If you love French food, nightlife and a change of scene every day, St. Martin has more of them on one small island than almost anywhere in the Caribbean. Our own homes are on St. Croix, which tells you our leaning. Here's how the two compare, with the numbers for you to check.

One country or two, in numbers

Two countries or one

Start here, because it's part of what makes St. Martin fun. One island holds two countries. The French side, Saint-Martin, covers the north, with Marigot as its capital. The Dutch side, Sint Maarten, covers the south, with Philipsburg as its capital. The road runs between them with no stop, and you'll need no additional documents to cross. Prices switch between euros and Caribbean guilders, and U.S. dollars are widely welcome. French, Dutch and English are all official on one side or the other, and you'll hear plenty more besides. A writer in Go World Travel described the French side as a bit laid back with a European feel, and that's a good summary.

St. Croix has one country and one currency, and your phone and bank card behave just as they do at home. What it has instead of a border is two towns with different personalities: Christiansted, with its harbor and Danish fort, and Frederiksted on the sunset side. You'll have both within an easy drive, and there's nothing to convert.

Passports and coming home

St. Martin asks U.S. citizens for a passport valid for the length of your stay, along with proof of a return or onward flight. It's a simple requirement for most travelers. If your family's passports have lapsed or a child doesn't have one, though, it adds time and money before you've even packed.

St. Croix, being American soil, takes your REAL ID or a similar TSA-accepted card, and no passport comes into it. That makes it a good answer for a last-minute trip, or for a big group where someone always has an expired passport.

Coming home, you'll notice the difference again. The standard allowance from a foreign country like St. Martin is $800 of goods with one liter of alcohol. Coming home from St. Croix doubles that to $1,600 and raises the alcohol to five liters, if one's made locally. A box from the Cruzan distillery takes care of that nicely.

On safety, the U.S. State Department had Sint Maarten at Level 1, its lowest, in August 2026. The French side falls under its own advisory. Levels can change, so check travel.state.gov before you go.

Room on the island

The arithmetic here is simple. St. Martin has 34 square miles and somewhere between 74,000 and 80,000 residents, which is more than 2,100 people per square mile. St. Croix's 84 square miles hold 41,004 residents, about 490 per square mile. That's more than four times the elbow room before you count visitors, and St. Martin sees a lot of them. Philipsburg is a big cruise port; the Go World Travel writer's advice on Orient Beach is that it's a must-visit "except when five or more cruise ships are in port." Frederiksted's pier on St. Croix handled 3 to 8 ships monthly over 2023 and 2024.

Whether that's good or bad depends on you. If you like the feeling of a lot going on, St. Martin has it, and you'll have your choice of beach bars and restaurants within a few minutes of anywhere. If you've come to read a book on a quiet deck, you'll enjoy our side of things.

Beaches

St. Martin counts 37 beaches on its 34 square miles, and they cover a lot of ground for such a small place. Orient Beach on the French side is the lively one, with a market nearby. Pinel Island is a five-minute boat ride from Cul-de-Sac and has shuttles about every half hour. Maho Beach is famous for the jets coming in over it to Princess Juliana Airport, and you should mind the warnings about the airport fence and enjoy the show from a safe distance. It's the sort of thing you'll want to see once.

St. Croix's beaches are more spread out, and they're quieter for it. For a sunset drink and calm water, try Rainbow Beach. Cane Bay pairs a beach bar with a dive shop. Sandy Point, a wildlife refuge, opens its empty miles for free on winter weekends. If you'd like to stay right on the water, take a look at our beachfront homes. The rest are in our beach guide.

Food

St. Martin wins this one for most people who care about it. Grand Case on the French side is often called the French food capital of the Caribbean, with a row of restaurants along the water, and the neighboring areas of Maho and Simpson Bay on the Dutch side have most of that side's dining. If you're planning your trip around dinner, go, and book ahead.

St. Croix cooks differently and very well. Look for kallaloo, fungi, saltfish and pates from a roadside stand, and then sit down at a harbor table in Christiansted. With a kitchen in your rental, you can also shop for fresh fish and cook at home. Begin with Crucian food and Christiansted's restaurants. The drinks are local too: Cruzan rum, breadfruit vodka at Sion Farm and beer at Leatherback Brewing are all made on the island, and you can visit all three.

Under the water

Of these two, St. Croix is the dive island. Walk in at Cane Bay and you can swim out to the island's famous wall, renting your tank on the way. There's also a fine shore dive at the Frederiksted Pier. Snorkelers head to Buck Island, a federal monument just offshore, where a trail on the seabed is marked with plaques. It's an easy half-day trip by boat from Christiansted.

St. Martin has good snorkeling off spots like Pinel, and boats that'll take you out for a dive. Most people go there for what's on land, and that's fine. It has plenty of it.

Evenings

If you want to go out late, St. Martin has the casinos on the Dutch side and more bars and clubs than a small island should be able to hold. Philipsburg's Front Street is full of shops for browsing too. St. Croix's nights are gentler: dinner at the Christiansted boardwalk with a band on weekends, a street party, Jump Up, in some months, or a night paddle on Salt River's glowing bay. Then there's a drink on your own deck and a good night's sleep.

Driving

St. Martin drives on the right, and it's an easy island to rent a car on. It's also a small island with a lot of cars. The Simpson Bay drawbridge lifts for boats, and delays there can back up traffic, so allow extra time for the airport. You'll want to choose your side with some care, since it shapes where you'll eat most evenings.

St. Croix keeps left, which you'll get used to quickly with our short guide. The island's size works for you. It's an easy run between the two towns, on open road. Renting a car tells you what you need to know.

Flights

St. Martin's main airport is Princess Juliana on the Dutch side, with nonstops from the U.S., including JetBlue from Fort Lauderdale, about three hours. A smaller airport at Grand Case handles short hops to the neighboring islands, and its role as a hub is a real plus if you want to see St. Barts or Anguilla too.

Nonstops reach St. Croix as well, with Miami all year and more cities in winter, and San Juan connects by a short hop. Getting here has the dates. If you were wondering, Contour Airlines started flying between St. Thomas and St. Maarten in October 2026, so you can even combine the two regions without going back through the mainland.

History and culture

St. Croix's colonial history is easy to see, because whole towns of it are still standing. Christiansted's harbor is lined with Danish buildings in the care of the National Park Service. You'll remember the yellow fort and the Steeple Building, dating from 1751. Walk the arcaded streets behind them, then take the Alexander Hamilton story around town. On the west side, Frederiksted has its fort and the story of emancipation in 1848. Estate Whim shows you how the sugar estates worked.

St. Martin's story is in the split itself. Marigot's pretty colored buildings and Philipsburg's Front Street still feel like two different countries, because they are. Part of the fun is hopping between the two for lunch and for dinner, and you can find a French bakery and a Dutch casino within a short drive of each other.

Bringing the family

A family with passports and a love of variety will have a great time on St. Martin. Beaches like Orient and the boat over to Pinel keep everyone busy, and restaurants are never far. If you've got a big group, though, the passport question can decide this for you, since everyone needs one, including babies. For St. Croix, adults just need a REAL ID or other accepted card, and U.S. citizen children flying domestically don't need one for the TSA checkpoint. Then you've got a house with its own pool, a kitchen, plus a snorkel trail at Buck Island for older kids. Traveling with kids has more on what works here, and family homes are listed together.

Prices and paying

You'll want to set up your budget a little differently for each. On St. Martin, you'll see prices in euros on the French side and in Caribbean guilders on the Dutch side, where 1.79 guilders make a U.S. dollar, and it's worth checking your card's foreign transaction fees. On St. Croix, everything is in dollars, and your cards and phone plan work as usual.

For a place to stay, look at the full total on your dates and compare it with what you're finding on St. Martin. Our rentals page shows each home's total, including fees and tax. If you're traveling with a group, a house can compare very well against several rooms in a resort.

Can you do both?

You can, and it's more practical than it used to be. Contour Airlines began flying between St. Thomas and St. Maarten twice a week in October 2026, with St. Croix a quick flight beyond. You'd start with a passport and a few days of French food, fly over to St. Thomas, and then take a seaplane or a small plane to St. Croix for the rest of your stay. Since only some days work, check the schedule first and leave yourself room for a delay. If you've got ten days or more and you love the idea of both, it's a fine trip.

How to choose

A week on each

A St. Martin week might go like this: Orient Beach one day, a boat to Pinel the next, an afternoon of jets at Maho, a walk around Marigot and its pretty colored buildings, a shopping morning on Front Street, dinner in Grand Case more than once, a day trip to a neighboring island with your passports in a dry bag. There's a lot to do, and you'll sleep well.

A St. Croix week might go like this: Buck Island on Monday, Cane Bay on Tuesday, the fort and the boardwalk on Wednesday, the East End on Thursday, Frederiksted and Rainbow Beach's sunset on Friday, the rainforest and the rum tour on Saturday, and back to your favorite beach on Sunday. All of it sits within easy reach of one house, and you won't need to change a dollar. The seven-day itinerary fills in the details.

Staying on St. Croix

If St. Croix is your pick, here's where to start. Couples often like Caribbean Blue Hideaway, a one-bedroom close to town, or Sunset Sea-Clusion on the sunset side. Families can look at Toes in the Sand for eight or Shoy's Beach House for twelve. You'll see live dates and totals on our rentals page, and our team on the island answers at 340-205-3929.
