Islands That Don’t Require a Passport For U.S. Travelers—But Feel Like an International Escape

Dreaming of a beachy escape but don’t have a passport? Don’t worry—paradise is still within reach. Whether you’re craving turquoise water, white-sand beaches, or a culture fix, there are several incredible islands where U.S. citizens can vacation without needing to dig out that little blue booklet. From the Caribbean to the Pacific, here are the best islands that don’t require a passport (and still deliver a dreamy getaway.)

Puerto Rico might just be the crown jewel of passport-free travel for Americans. Wander through the colorful cobblestone streets of Old San Juan, take a nighttime kayak through the glowing bioluminescent waters of Mosquito Bay, or lounge on Flamenco Beach in Culebra (often ranked among the best beaches in the world.) If you’re feeling adventurous, head to El Yunque, the only tropical rainforest in the U.S. National Forest System, where you’ll find jungle trails and waterfall swims.

San Juan is a major hub for art and nightlife. Be sure to check out the hip Santurce neighborhood for murals, pop-up galleries and incredible street food. Snorkel coral reefs off Vieques, catch some waves in Rincón, or dance to reggaeton under the stars. Basically, Puerto Rico brings the heat—all without needing a passport.

Direct flights to San Juan (SJU) are available from most major U.S. cities, including Miami (~2.5 hrs), New York (~4 hrs), Chicago (~5 hrs) and Dallas (~5 hrs). 

The U.S. Virgin Islands (St. Thomas, St. John and St. Croix) are a postcard-perfect mix of beach bliss, natural beauty and history. St. Thomas is your go-to for shopping and sightseeing, with duty-free deals and picture-perfect Magens Bay. If you want more nature, head to St. John, where two-thirds of the island is protected as Virgin Islands National Park. Hike to ancient petroglyphs, snorkel Trunk Bay’s underwater trail, or just find your perfect beach.

St. Croix has a slower pace, but just as much to offer—especially if you love diving. Buck Island’s coral reef is teeming with marine life, and the island’s blend of rainforest and arid terrain makes it feel like two destinations in one. You’ll also find historic towns, distilleries and that laid-back Caribbean vibe.

Bonus: U.S. currency, cell service and no customs lines!

Direct flights are available to St. Thomas (STT) and St. Croix (STX) from cities like Miami (~3 hrs), Charlotte (~4 hrs) and New York (~4 hrs). Ferries connect St. Thomas and St. John as well, so you can easily hop between islands.

If you’re looking for something truly different, set your sights on Guam. This Western Pacific has island vibes, Chamorro culture and a unique World War II history. You can explore turquoise bays like Tumon and Gun Beach, snorkel vibrant reefs, or dive at the famous Blue Hole. And if history is more your thing, check out the War in the Pacific National Historical Park.

Guam’s duty-free shopping is top-tier (luxury brands at a fraction of the cost) and the weather is always beach-ready. It’s a bit of a trek to get there, but once you arrive, you’ll find a blend of laid-back island life and fascinating history that makes it well worth the trip.

Most travelers fly to Guam (GUM) via Honolulu. From the mainland U.S., expect a total travel time of 13–16 hours with connections through LAX, SFO, or HNL (Honolulu). United Airlines offers the most direct options.

If you’re dreaming of tropical beaches, the Northern Mariana Islands (especially Saipan, Tinian and Rota) are a much less trodden area for U.S. travelers.

Saipan is the largest and most visited, with resort comforts, beautiful beaches and access to incredible dive spots. Tinian and Rota are more of a slower, quieter escape. Get lost in WWII history, hike jungle trails and relax on beaches where the water is so clear, you’ll think you’re in a screensaver.

These islands are also a great base for exploring more of the Pacific or Asia while still staying on U.S. soil.

Fly into Saipan International Airport (SPN) via Guam—United Airlines operates flights between the two islands (about 45 minutes). Getting to Guam requires flying from the mainland U.S. to Honolulu and then onward to Guam, with total travel time around 16–20 hours.

It’s technically a U.S. state, but let’s not forget: Hawaii feels like a whole different world. And yes, you can absolutely go without a passport.

From the volcanic cliffs of the Big Island to the lush jungles and surf breaks of Kauai, Hawaii offers that quintessential island escape without any international travel logistics. Each island has its own vibe: Oahu brings the buzz of Honolulu and iconic Waikiki Beach, while Maui offers a slower pace, luxury resorts and the scenic Road to Hana. The Big Island is a land of contrast—lava flows, snow-capped peaks, black-sand beaches—while Kauai delivers waterfall-laced hikes and dramatic Na Pali coast views.

Hawaii is also a goldmine for wellness seekers and outdoor lovers. Think sunrise yoga on the beach, paddleboarding with sea turtles and fresh poke bowls from food trucks.

Direct flights are easy to find, especially from the West Coast. LAX and SFO offer multiple daily flights to Honolulu, Maui, Kona and more. From the East Coast, you’ll likely connect through a major hub, with total travel time ranging from 5 hours (from California) to 11+ hours (from NYC or Atlanta).

If you desire to really get off the beaten path, American Samoa is about as untouched and authentic as it gets.

This cluster of volcanic islands in the South Pacific promises rugged landscapes, lush rainforests and pristine beaches. It’s ideal for travelers looking to unplug and connect with nature—and with Polynesian culture. The National Park of American Samoa spans rainforest, coral reefs and mountain peaks, making it perfect for eco-travelers and hikers.

It’s not a party island, it’s more peaceful, raw and wildly beautiful. If you’ve ever dreamed of stepping into a postcard and staying awhile, this is the place.

Fly to Pago Pago (PPG) via Honolulu (HNL)—Hawaiian Airlines offers a couple of weekly flights. From the mainland U.S., you’ll first fly to Hawaii, and then it’s about 5.5 hours to American Samoa. Total travel time is typically 16–18 hours with layovers.

Correct—if you’re a U.S. citizen, you don’t need a passport to visit these destinations. But you do need a valid government-issued photo ID (like a driver’s license) and proof of citizenship (like a birth certificate). Some airlines also accept enhanced driver’s licenses, which speed things up at the airport.

Every airline is a little different, so double-check their ID requirements before you book. And don’t forget about the Real ID deadline. It applies to these trips, too.

If you’re traveling with kids, each child needs their own ID. For little ones under 16, a birth certificate usually works. Older teens might need photo ID depending on the airline, so plan ahead.

Caribbean destinations like Puerto Rico and the U.S. Virgin Islands are easy to reach from the East Coast, with direct flights from cities like Miami, NYC and Atlanta. Pacific territories like Guam and American Samoa usually require connections through L.A., San Francisco, or Hawaii.

Ferries connect the U.S. Virgin Islands, and Puerto Rico offers ferries and quick flights to smaller islands like Culebra and Vieques. In the Pacific, most island-hopping is done by air, though some ferries operate on limited routes.

You’ll find rental cars, taxis, and public transportation in most areas. Puerto Rico has the best road network and even a metro system in San Juan. On smaller islands, scooters and rental cars are your best bet for exploring.

Caribbean islands like Puerto Rico and the U.S. Virgin Islands are warm year-round, but keep an eye on hurricane season (June–November).

Pacific islands like Guam and American Samoa have a tropical climate, with a dry season (typically December through June) offering the best weather for outdoor fun.
