St. Croix vs St. Thomas

For a week in a rental house with your own car, we'd point you to St. Croix: it has more than twice the land of St. Thomas, a fraction of the cruise ships, a wall dive you can walk to and a pair of old Danish towns. St. Thomas is the better pick if you want a resort with everything on site, the widest choice of flights or a serious shopping day. We look after homes on St. Croix, so weigh that as you read. The numbers are all there to check.

The two islands in numbers

How the two compare for a house rental

Most comparisons of these islands ask which one is better. We'd ask what kind of week you've got in mind. If you're picturing your own kitchen and pool, a car in the drive and a different beach each morning, the things that matter are how much room there is, how easy the driving is, and what's within reach from your own front door. That's what this page looks at. If St. John is on your list too, we've compared it here.

Room to spread out

The two islands hold almost the same number of people. Census takers in 2020 found 41,004 on St. Croix and 42,261 on St. Thomas. But St. Croix has 84 square miles to put them on, and St. Thomas has 32. St. Croix stretches roughly 22 miles by 7, with rolling hills peaking at Mount Eagle. St. Thomas is smaller and higher, with Crown Mountain at 1,555 feet, and its houses and roads climb up and over steep slopes.

You feel the difference on the way to the grocery store. On St. Croix you'll drive through open country between Christiansted on the northeast side and Frederiksted on the west, and past farmland and old sugar mill ruins on the way. A house here can mean a long view and a quiet road, and that's what a lot of our guests come for.

Ship days

Ships are a way of life on St. Thomas. The West Indian Company, which runs its main dock, reported 302 ship calls and 946,199 passengers through May 31 of fiscal 2026, and its projections for the following season run to about 360 calls and more than a million passengers. The docks at Havensight and Crown Bay are busy, well run and good at what they do. If you're a shopper or you like a lively waterfront, a ship day in Charlotte Amalie is a fun day out.

St. Croix sees far fewer. Frederiksted's pier, out west, took about 3 to 8 ships a month in 2023 and 2024. When one's in, restaurants, bars and dive shops near the pier have a good day and the town has a bit of a buzz. Beyond Frederiksted, you'd hardly know. For a house guest, this mostly means that the roads, the beach parking and the restaurant tables don't change from one day of the week to the next.

Driving a rental car

You'll drive on the left on both islands, in the usual left-hand-drive American cars. It's the one U.S. habit you leave at home, and most people have it down by the second day. Read our left-side driving tips before you pick up the keys, and at renting a car to see how it works here.

St. Croix has the easier roads for it. With more land and gentler hills, you've got long straight stretches between the towns. Henry E. Rohlsen Airport sits between the two towns, so it's a quick run to either. On St. Thomas, the steep roads and hill starts take more attention, and many visitors there use taxis instead. Neither has Uber or Lyft, which leaves you with a rental or a cab.

Beaches you can drive to

St. Thomas's famous beach is Magens Bay, a long, sheltered crescent on the north side. It's run by an authority, with an admission of $7 per person for non-residents over 12, $2 for parking, and staffed hours from 7 a.m. to 5:30 p.m. Lifeguards are on duty for most of the day. It's a beautiful spot, and it's well worth a visit if you're in St. Thomas for the day.

A St. Croix week gives you several different coasts to choose from, and most days you'll pick by mood:

• North shore: Cane Bay, where the bar and dive shop are steps apart.
• West coast: Rainbow Beach, for calm water and a sunset.
• The Shoys east of Christiansted, where Shoy's Beach House sits right on the beach.
• Southwest corner: Sandy Point, an undeveloped refuge beach, free to enter on open weekends from fall through March.

Reefs and shore dives

This is the part that settles it for divers. The Cane Bay Wall begins some 40 feet under, a short swim from the sand, then falls away for thousands of feet. You can rent a tank over the road and walk in. Over on the west coast, you can also dive the Frederiksted Pier without a boat. If you've got a house near either, you can be in the water before breakfast and home for lunch.

Snorkelers have Buck Island, a national monument just off the northeast coast. President Kennedy created it in 1961, and the park service quotes his description of it as the finest marine garden in the Caribbean Sea. Bill Clinton expanded it in 2001, and it now covers 19,015 acres, most of it under water. There's a marked underwater trail on the eastern tip, and the way there is a boat run by an authorized concessioner, a half-day or full-day trip from Christiansted. At night, you can kayak Salt River's bioluminescent bay.

St. Thomas has good water too, and it's within easy reach of St. John's national park by ferry. Its diving is mostly done from boats, which suits anyone who'd rather have someone else carry the tanks.

Two towns or one

A week on St. Croix has two evenings out, and they're very different. Christiansted has the boardwalk, a run of harbor restaurants, and a National Historic Site with five Danish buildings, among them the fort and the old Steeple Building, dating to 1751. Founded in 1952, it's the territory's first national park unit. Frederiksted is the quieter town on the sunset side, with the long pier and Fort Frederik.

St. Thomas has one big town. Charlotte Amalie is the territorial capital, with 14,477 residents, a working harbor and a shopping district that visitors have been coming to for decades. It's a lively place to spend a day, and if duty-free shopping is part of your trip, it's the place to do it.

A house for your group

Here's where the numbers get specific to us, since they're the homes we know. If you're bringing a big group, Shoy's Beach House has six bedrooms and room for twelve, and The Buck Island Overlook is a five-bedroom with a private pool over the water. For a family of six to eight, Dragonfly Villa and Toes in the Sand sleep eight. Couples look at Caribbean Blue Hideaway or Moko Vista. Enter your dates on our rentals page for each home's total, then hold it up against anything you're looking at on St. Thomas. Comparing one house against one house on your own dates is the only fair way to do it, and it takes a few minutes.

A kitchen changes the math too. A single supermarket stop after landing can cover the week's breakfasts and a few dinners, and our guide to villas and hotels runs through the rest.

Flying in

St. Thomas has more flights from more places, and that's worth saying plainly. Recent announcements alone include Southwest from Orlando and Baltimore, Delta from New York, Sun Country from Minneapolis in season, and Breeze from Tampa this winter.

St. Croix's schedule is smaller, and it's better than many people assume. Miami runs all year, and in the winter months you can add Charlotte, Atlanta, Newark and Chicago, several of them on Saturdays, which suits a weeklong house rental very well. Getting here has the dates.

The two work together well. Plenty of people land on St. Thomas with a good fare, then make the 20-minute-odd hop on one of the small airlines. If your city only flies to one of them, you're not stuck.

Seeing both on one trip

You don't really have to choose, because they're so close. There are three ways across:

• Seaplane. Seaborne goes downtown to downtown, landing on the Charlotte Amalie waterfront after about 25 minutes. Boarding on the boardwalk and landing downtown makes it a great day trip. Check schedules with the airline.
• Small plane. Small airlines such as Fly the Whale and Cape Air link the airports.
• Ferry. From Gallows Bay at 8 a.m. every day but Tuesday, arriving at 10:10, with the return sailing at 3 p.m. Fares on the island's tourism site are $85 and $150 round trip, so ring (340) 473-1322 before you count on them.

We'd suggest staying on St. Croix and going over for a day of shopping and a look at Charlotte Amalie. The plan is in our day-trip page. Since it's a domestic hop, no passport comes into it.

Food and evenings

St. Thomas has plenty of places to eat, from marina restaurants to hotel dining rooms, and Charlotte Amalie's lunch spots are handy on a shopping day. With a St. Croix house, you'll probably eat at home a few nights and go out for the rest. That means a table on the harbor in Christiansted one night, a sunset dinner in Frederiksted the next, and maybe something at Cane Bay after your north shore day. Local cooking is easy to find too: look for kallaloo, fungi and pates, and let our Crucian food page steer you.

If you like to know where your drink comes from, St. Croix makes it. You can tour Cruzan at Estate Diamond, taste at Captain Morgan's, try Sion Farm's breadfruit vodka on the boardwalk and have a beer at Leatherback. Both islands share the same generous duty-free rules if you're bringing bottles home.

Bringing the kids

For a family, it's mostly a question of resort or house. A St. Thomas resort gives you kids' programs, a pool with a crowd in it and dinner a short walk away, and that's a good week if it's what you want. A St. Croix house means a private pool, room for grandparents and cousins, and a kitchen for the fussy eaters. You'll have shallow water for little swimmers, a fort to explore and, for bigger ones, a boat to Buck Island. Traveling with kids covers the week in more detail, and our family homes have their own page.

A day out from each island

From St. Thomas, the classic day out is St. John, with its national park and its own beaches, and the ferries make that very easy. It's a real point in St. Thomas's favor, and worth counting if you've got your heart set on St. John. From St. Croix, the classic day out is Buck Island, then perhaps sunrise at Point Udall, as far east as the island goes, or the seaplane to St. Thomas itself. You've also got Mahogany Road through the rainforest, where the Domino Club makes a good stop, and the Annaly Bay walk. That's plenty for a week, all of it within reach of one front door.

Which island for you

A week from a St. Croix house

Here's a week as many of our guests would plan it. Saturday, land, shop at the supermarket and get to the pool before sunset. Sunday, an easy drive west, lunch in Frederiksted, and sundown at Rainbow Beach. Monday, a half-day at Buck Island by boat. Tuesday, Cane Bay, with a dive or a snorkel and lunch at the beach bar. Wednesday, over to St. Thomas by seaplane to shop. Thursday, the fort in the morning and the boardwalk for dinner. Friday, the Cruzan distillery and Estate Whim, then your favorite beach again. Our seven-day itinerary has the longer version.

Questions people ask

For a villa vacation, which of the two is better?

For a house and a rental car, St. Croix: more than twice the land, far fewer cruise ships, shore diving and two towns to drive between. For a resort with everything on site, St. Thomas has more choices.

Which is bigger, St. Croix or St. Thomas?

St. Croix, at 84 square miles to St. Thomas's 32. They have nearly the same population: 41,004 on St. Croix and 42,261 on St. Thomas in the 2020 census.

Will I need my passport on either island?

Americans flying from home won't, since both are U.S. territory. Bring a REAL ID or other ID the TSA accepts. See no passport needed.

How many cruise ships go to each island?

St. Thomas's main dock operator reported 302 ship calls through May of fiscal 2026. On St. Croix, Frederiksted's pier handled a handful, 3 to 8 each month in 2023 and 2024.

What's the quickest way between them?

The seaplane, at about 25 minutes. Small planes link the airports, and the QE IV ferry takes a little over two hours. Many guests do it as a day trip.

Which island has better diving?

For shore dives, St. Croix: the Wall at Cane Bay and the pier at Frederiksted are both walk-ins. St. Thomas divers mostly go by boat. See diving St. Croix.

Is St. Croix cheaper than St. Thomas?

Compare your own dates. Our search gives every home's full total, so you can set it next to a St. Thomas house for the same week. A kitchen and a house for the whole group often change the math more than the island does.

Do both islands keep left?

Yes, in regular left-hand-drive American cars. St. Croix's roads are gentler, with long straight stretches between its two towns.

Could I land on St. Thomas and stay on St. Croix?

Yes, when the fare is better. Small planes cross in under half an hour.
