6 Caribbean Islands Americans Can Visit Without a Passport

You don’t need to leave the country to find turquoise water, white sand, and that unmistakable Caribbean breeze. For U.S. citizens, several Caribbean destinations offer a full island experience—with no passport required. Whether you’re looking for a weekend escape or a longer tropical recharge, these places combine accessibility with island charm.

Here are six Caribbean destinations where you can go passport-free.

St Croix: The Art of the Vibe 

St. Croix has always had its own vibe (that’s actually now part of the island’s branding). It’s quieter than its siblings, maybe less flashy—but if you know, you know. This is the island of old-world charm and new-world flavor.

The food scene is the secret weapon here: bold, fresh, and rooted in culture. Think ocean-to-table mahi at Savant in Christiansted, the perfect fish tacos in Frederiksted. You can follow it all with a rum tour at the legendary Cruzan distillery or simply a bottle of the island’s own Mutiny vodka on ice.

Add in Buck Island’s underwater trails, an untouched forest on the west end, and days that end with fried johnnycakes and sunset over Frederiksted — and you’ve got an island escape with real soul. No passport needed. Where to stay? Right now, we love smaller options like The Fred in Frederiksted and the historic Company House Hotel in Christiansted.

St. Thomas: Big Fun, Bold Flavors

St. Thomas is the energy island. Beaches? Of course. But it’s the beach and the bar. The boat and the rum punch. It’s where things happen—and the pulse is real.

Start with Magens Bay, a stretch of calm blue water perfect for lazy swims and paddleboarding. Then head to Red Hook for a mix of beach bars, fresh-caught seafood, and music that plays until the last drink is poured. Looking for luxe? Head up to the hilltop villas with panoramic views or book a suite at Frenchman’s Reef.

This island doesn’t sleep early. It’s built for beach days and late nights. All with no passport required.

Where to stay? If you want the essence of St Thomas, it’s the legendary, all-inclusive Bolongo Bay, no questions asked. If you want something bigger, go for the Buoy Haus, part of the Frenchman’s Reef complex with a private-island feel.

St John: Villas, Views and Toes in the Sand 

The island of St. John is stunning—it’s one of the most beautiful islands in the entire Caribbean, in my view. Two-thirds of it is national park, and you feel it: wild beaches, quiet hikes, nothing overbuilt. But there’s also a layer of low-key luxury here that makes it endlessly livable.

Villas are the name of the game—hillside homes with infinity pools and Coral Bay views. It’s villa culture, island style. But finding your villa isn’t always easy — that’s why we recommend working with Blue Sky Luxury Travels — think of them as your personal villa concierge.

And now, there’s the newest hotel, the adults-only  The Saint, bringing a boutique hotel vibe right into Cruz Bay with just the right blend of energy and intimacy.

You can spend the day beach-hopping across Cinnamon, Trunk, and Maho Bays, stop at a beach bar with your feet in the sand, and head back to your villa for grilled fish under the stars. It’s untamed and elevated all at once.

Puerto Rico, The Whole Caribbean, Wrapped Into One

Puerto Rico is where everything comes together: the music, the mountains, the flavors. You don’t need a passport—and you don’t need a plan, either. This island gives you everything.

Start in San Juan, where centuries-old Spanish forts shadow buzzing nightlife and oceanfront dining. Then head out: to El Yunque’s rainforest trails, to coffee farms in the hills, to the surf towns of the west coast. Want luxury? Book Dorado Beach. Want soul? Hit La Placita for salsa and rum.

Puerto Rico has its own rhythm, and once you’re in it, you’re hooked. It’s not just a place to visit—it’s a place to return to. This island is big and boasts all kinds of hotels; if I had to pick a favorite, it would almost certainly be the O:LV hotel in Condado — from the lagoon-view bathrooms to the sexy vibe. When I first stayed there, it changed everything I thought about Puerto Rico’s hotel sector. And it still does.

Vieques: The Untamed Island

Vieques feels like the Caribbean before the world found it. Wild horses roam the hills, the beaches are often empty, and the boutique hotels are tucked into nature like they’ve always been there.

This is where you go to let go. Spend the day swimming at Playa La Chiva or Sun Bay, take a sunset ride along the coast, and then—if you’re lucky—kayak into the glowing waters of the bioluminescent bay under a moonless sky. At night, retreat to a villa-style stay like El Blok or Finca Victoria, where the rooms are as offbeat as the island itself.

It’s peaceful, raw, and deeply beautiful. No lines, no stress, no passport. We like the island’s smaller places to stay, from the strikingly-designed El Blok to the off-the-grid Hix Island House.

Culebra: It’s All About That Beach 

Culebra isn’t big. And that’s the point. It’s a place you whisper about, not post about. But those who’ve walked Flamenco Beach know—it’s one of the best in the Caribbean, period.

The water here is glass-clear. The sand is white and soft. And the island itself? Simple. Quiet. No big resorts. No cruise ships. Just a few guesthouses, a handful of beach bars, and the sound of water hitting shore.

There’s Club Seaborne, a breezy hideaway with a marina view, and a tiny airport where the planes land low enough to rattle your Piña Colada. It’s part dream, part time capsule—and all yours.
