Maybe you’ll paddle glowing waters in Puerto Rico, shop duty-free in St. Thomas, or catch a glimpse of Chamorro traditions out in the Pacific.

Puerto Rico blends Spanish colonial charm with all the comforts of modern travel. Old San Juan, with its candy-colored buildings and cobblestone streets, feels like a postcard from the 1500s.
Beyond the beaches, the island surprises you. El Yunque National Forest stands as the only tropical rainforest in the U.S. system. I love hiking its lush trails and cooling off in waterfall pools.
Some must-try experiences:

U.S. Virgin Islands: St. Thomas, St. John, and St. Croix
Each of these three islands has its own vibe. All of them offer crazy-clear water for snorkeling and diving.
St. Thomas is a shopper’s paradise, especially in Charlotte Amalie’s duty-free stores. Magens Bay Beach is a mile of pure, calm bliss. Fun fact: folks here drive on the left.

Mackinac Island sits in Lake Huron, tucked between Michigan’s peninsulas. No cars allowed—just bikes and horses.
Rent a bike near the ferry and cruise the eight-mile loop around the island.
Fort Mackinac stands high on the bluffs, offering living history and cannon blasts in summer.
The Grand Hotel is iconic, its 660-foot porch overlooking the water. Presidents and celebrities have stayed here since the 1800s.

The Northeast hides some island gems. Martha’s Vineyard and Nantucket ooze classic New England style, while Block Island brings dramatic cliffs and peaceful beaches.
Martha’s Vineyard: New England Coastal Charm
Martha’s Vineyard feels like pure New England magic. Just seven miles off Cape Cod, it’s close but feels a world away.
Six towns dot the island, each with its own flair. Edgartown is all stately captain’s houses and tidy gardens. Oak Bluffs bursts with colorful “gingerbread houses” that look straight out of a storybook.
How to Get There:
- Ferry from Woods Hole (about 45 minutes)
- Seasonal ferries from Boston and New York
- Walk-on tickets? No reservation needed
The island is big—100 square miles of beaches, woods, and tiny harbors. Don’t skip the red clay Aquinnah Cliffs at sunset. State Beach is calm and perfect for families.
Celebrities and presidents love it here, but honestly, it’s accessible to everyone. Strict building rules keep the charm intact. Summers are lively, but I prefer the quiet, golden days of fall.
Nantucket: Timeless Massachusetts Getaway
Nantucket feels like a step back in time. It’s 30 miles off Cape Cod, with cobblestone streets and gray-shingled cottages.

The Mohegan Bluffs shoot up 200 feet above the Atlantic, and honestly, these clay cliffs might offer the most dramatic coastal views in New England. There’s a long wooden staircase that zigzags down to a hidden beach—totally worth the climb back up, even if your legs complain later.

The ferry runs from Point Judith, Rhode Island, and there are seasonal boats from Connecticut and New York. Day-trippers come and go, but if you can swing an overnight stay, you’ll get to see a quieter side of the island. I’d aim for spring or fall; the weather’s just right, and the crowds thin out.
Remote Pacific Island Adventures
If you’re craving adventure, the Northern Mariana Islands offer some of America’s most remote tropical escapes. These Pacific gems have wild beaches, world-class diving, and rich cultural heritage—and you don’t even need a passport.
Northern Mariana Islands: Saipan, Tinian, and Rota
I genuinely think the Northern Mariana Islands are one of America’s best-kept secrets. Fourteen islands dot the South Pacific here, and you get all the tropical vibes with none of the international travel hassle.
Saipan is the main hub, and it’s also the biggest island in the chain. The climate? It’s so steady that it actually holds the Guinness World Record for stability—think 80°F all year, no wild swings.
If you love beaches, check out Micro Beach, Lau Lau Beach, and Landing Beach. They’re pristine, and the sand feels almost too soft to be real. Divers rave about the visibility here—sometimes over 100 feet, which is a little surreal.
Eagle Ray City is a must for anyone into diving. I’ve seen dozens of eagle rays swooping through the water on a single dive—unforgettable. History fans can explore WWII wrecks scattered across the sea floor, which adds a whole other layer to the experience.
Tinian and Rota move at a slower pace than Saipan. You’ll find secluded beaches and untouched landscapes, perfect if you want to unplug.
The Grotto on Saipan is a limestone cavern that’s equal parts eerie and beautiful—divers love it. Just a heads-up: December through June brings the best weather, but typhoon season hits from July to October.
If you’re hungry, try local kelaguen—it’s this zesty blend of chicken, lemon, coconut, and peppers. Estufao stew is another Chamorro favorite, and honestly, it’s the kind of comfort food you remember.
Island Highlights: Natural Wonders, Culture, and Activities
America’s islands bring together stunning beaches, wild horses, coral reefs, and cultures shaped by centuries of isolation. You can kayak through sea caves, join quirky festivals, and try foods you’ll never find on the mainland.
Beaches, Wildlife, and National Parks
No two island beaches look the same. Some are all about white sand, while others have rugged coastal cliffs that make you stop and stare.
Assateague Island stretches for 37 miles along Maryland and Virginia, and wild horses wander right along the shore. Seeing them graze with the ocean in the background? It’s an iconic photo op.
Dry Tortugas National Park sits on seven tiny islands in the Gulf of Mexico. The crystal-clear waters make for some of the best snorkeling and diving in North America. The coral reef here is the third-largest on the continent.
Many islands double as wildlife havens. Prince of Wales Island in Alaska has black bears fishing for salmon and sea otters drifting in kelp beds. The Tongass National Forest blankets much of the island, so you’re never far from nature.
North Carolina’s Outer Banks are a safe haven for nesting sea turtles and migrating birds. The Cape Hatteras National Seashore protects long stretches of wild coastline where you can walk for miles without seeing another soul.
Local Culture, Festivals, and Cuisine
Island life shapes its own culture, sometimes in ways you don’t expect. Tangier Island in Virginia’s Chesapeake Bay, for example, keeps a dialect that sounds straight out of 17th-century England. Locals use sayings and expressions you won’t hear anywhere else.
On Molokai in Hawaii, time just slows down. There are no traffic lights, no high-rises, and traditional culture still thrives. People here keep old customs alive, and you feel it in the air.
Seafood takes center stage on most islands. Tangier Island’s blue crab dishes are legendary, and the crab shanties serve up recipes passed down for generations.
Festivals pop up throughout the year, celebrating everything from maritime history to local music. You’ll find handmade crafts, regional foods, and a sense of community that’s hard to replicate anywhere else.
Adventure, Water Sports, and Relaxation
Kayaking? It’s honestly one of the best ways to explore American islands. I paddled through the crystal-clear waters of the Apostle Islands in Wisconsin, weaving in and out of sea caves.
Come winter, those same caves transform into shimmering ice cathedrals—totally surreal.
Over in California, the Channel Islands just call out to divers and surfers. I spotted dolphins and seals gliding through the protected waters—sometimes they come so close, you almost forget you’re not part of their world.
If you love hiking, you’ve got to check out Mackinac Island. There are over 70 miles of trails, and cars just aren’t allowed. That means the only sounds you’ll hear are your footsteps, the wind, and maybe the clip-clop of a horse-drawn carriage.
Biking around the island feels like stepping back in time. It’s honestly refreshing.
Craving pure relaxation? Little Palm Island in the Florida Keys might just be your dream escape. It’s an exclusive spot with no phones or TVs in the rooms, so you can really unplug.
I once had a spa treatment over the water there—imagine the sound of gentle waves and nothing else. It’s the kind of peace that’s hard to describe.
Of course, you’ll find water sports everywhere—fishing, sailing, and even whale watching, depending on where and when you visit. There’s always something new to try, and that’s half the fun of island life.
