Plan trip with AIHow to Reach Each Island: Ferries, Flights and Drives
Half the adventure of an island is the crossing — and half the planning headache, too. Some of America’s islands are a five-minute hop on a car ferry; others need a puddle-jumper flight, a reservation booked months ahead, or a boat you can only board on foot. Here is how you actually get to the islands in this guide, how long it takes, and whether you can bring a car.
| Island | How you get there | From | Crossing time | Car allowed? |
|---|---|---|---|---|
| Nantucket, MA | Fast ferry or traditional ferry | Hyannis, Cape Cod | 1 hr (fast) / 2¼ hr | Yes, but costly & book early |
| Martha’s Vineyard, MA | Car & passenger ferry | Woods Hole, MA | 45 min | Yes (reserve ahead) |
| Block Island, RI | High-speed or traditional ferry | Point Judith, RI | 30 min / 55 min | Yes, but bikes are better |
| Mackinac Island, MI | Passenger ferry only | Mackinaw City / St. Ignace | 15–20 min | No — cars banned |
| Apostle Islands, WI | Ferry to Madeline; boat tours for the rest | Bayfield, WI | 20 min | Only on Madeline Island |
| San Juan Islands, WA | Washington State Ferry | Anacortes, WA | 1–2 hr | Yes (long summer waits) |
| Catalina Island, CA | Express passenger ferry or helicopter | Long Beach / San Pedro / Dana Point | 1 hr | No — permit-only |
| Cumberland Island, GA | Passenger ferry (reservation required) | St. Marys, GA | 45 min | No — wilderness island |
| Assateague Island, MD/VA | Drive over the bridge | Berlin, MD / Chincoteague, VA | Direct | Yes |
| Key West, FL | Drive the Overseas Highway or fly | Miami (3½ hr drive) / EYW airport | — | Yes |
| Kaua‘i & Maui, HI | Fly (no ferries between islands) | Honolulu / mainland | 35–50 min inter-island | Rent on arrival |
| St. John, USVI | Passenger ferry | Red Hook, St. Thomas | 20 min | Rent on St. John |
The pattern to notice: the most magical islands are often the hardest to drive on. Car-free Mackinac, Cumberland and Catalina force you to slow down — and that is exactly why they feel like another century. Where cars are allowed, summer ferry reservations for vehicles sell out weeks ahead, so foot-passenger-plus-bike is frequently the smarter, cheaper play.
New England & the East Coast
Nantucket & Martha's Vineyard, Massachusetts
The quintessential New England island escapes. Nantucket is a preserved whaling-era gem of grey-shingled cottages, cobbled streets and open beaches, while nearby Martha’s Vineyard charms with its gingerbread cottages, lighthouses and laid-back villages. Both are summer classics reachable by ferry from Cape Cod. See our full guide to Nantucket.
Block Island, Rhode Island
Just off the Rhode Island coast, Block Island is a wonderfully unspoiled escape of rolling green bluffs, historic lighthouses, quiet beaches and clifftop walks (the Mohegan Bluffs are stunning). It feels a world away, yet it’s an easy ferry ride from the mainland.
Bald Head Island & the Outer Banks, North Carolina
Bald Head Island is a car-free (golf-cart-only) barrier island of maritime forest, marshes and the historic ‘Old Baldy’ lighthouse — blissfully peaceful. The wider Outer Banks string wild, windswept beaches, wild horses and lighthouses along the Carolina coast.
The South’s Barrier Islands and Wild Horses
Strung along the Atlantic and Gulf coasts is a chain of low, sandy barrier islands that most travelers drive right past on their way to bigger-name beaches. They are some of the wildest, most affordable island escapes in the country — and several come with a herd of free-roaming horses.
Tybee Island, Georgia
Just 20 minutes from downtown Savannah, Tybee is the easy barrier-island getaway — wide public beaches, a squat black-and-white lighthouse you can climb, shrimp shacks, and a laid-back, unpolished feel that the fancier resort islands have lost. It is the rare island you can reach on a whim, with no ferry and no reservation, which makes it a perfect day trip or long-weekend base.
Cumberland Island, Georgia
Cumberland is the opposite of Tybee: Georgia’s largest and wildest barrier island, reachable only by a reservation-required passenger ferry from St. Marys, with no shops, no cars, and a strict daily visitor cap. Feral horses graze the dunes and the ruins of the Carnegie family’s Dungeness mansion, live oaks drip with Spanish moss, and 17 miles of undeveloped beach stretch out empty. Day-trippers get a taste; campers and guests of the single inn, Greyfield, get the real thing.
Assateague & Chincoteague, Maryland and Virginia
Assateague is famous for one thing: the wild ponies that have roamed its dunes for centuries. You can drive straight onto the Maryland end or reach the Virginia side via the town of Chincoteague, where the annual July pony swim draws crowds. Beyond the horses it is a gloriously undeveloped national seashore — beach camping, kayaking through salt marsh, and some of the best low-key wildlife watching on the East Coast.
Padre Island, Texas
Padre Island National Seashore protects the longest stretch of undeveloped barrier island on Earth — roughly 70 miles of Gulf-facing dunes, sea-turtle nesting beaches, and world-class windsurfing on the Laguna Madre. It is the antidote to spring-break South Padre next door: drive-on beaches, star-filled skies, and a sense of genuine remoteness within a few hours of San Antonio.
| Island | State | Best known for | Access |
|---|---|---|---|
| Tybee Island | GA | Easy Savannah beach escape, lighthouse | Drive |
| Jekyll Island | GA | Historic district, sea turtle center | Drive (small toll) |
| Cumberland Island | GA | Wild horses, Carnegie ruins, solitude | Ferry (reserve) |
| Assateague / Chincoteague | MD/VA | Wild ponies, beach camping | Drive |
| Padre Island | TX | Longest wild barrier island, sea turtles | Drive |
Chasing horses and empty sand up the Atlantic seaboard pairs naturally with our best beaches in Florida guide once you cross into the Sunshine State.
The Great Lakes & Interior
Mackinac Island, Michigan
A genuine step back in time, Mackinac Island in Lake Huron has banned cars for over a century — you get around by bicycle, horse-drawn carriage or on foot. With its grand Victorian Grand Hotel, fudge shops and fort, it’s a charming, nostalgic summer escape unlike anywhere else.
The Apostle Islands, Wisconsin
Scattered across Lake Superior, the Apostle Islands are a wild archipelago of sandstone sea caves, lighthouses and pristine forest — magical to kayak in summer and, in the rare winter the lake ice holds, to walk to the famous ice caves (open on only about 2% of days, and last in 2026 and 2015). A stunning, underrated slice of Midwestern wilderness.
The West Coast & Pacific Northwest
The San Juan Islands, Washington
In the misty waters of the Pacific Northwest, the San Juan Islands are a haven of evergreen forest, quaint harbours and abundant wildlife — this is one of the best places in the world for orca (killer whale) watching. Hop between islands by ferry for a serene, scenic escape.
Catalina Island, California
Just off the coast of Los Angeles, Catalina Island feels like a Mediterranean getaway — the charming harbour town of Avalon, clear water for diving and snorkelling, and rugged interior hills roamed by bison. An easy, scenic escape from the Southern California mainland.
Tropical Paradise: Hawaii & the Keys
Kauai & Maui, Hawaii
For full tropical splendour, nothing beats Hawaii. Kauai’s emerald Na Pali cliffs and Maui’s Road to Hana and golden beaches are pure paradise. Each Hawaiian island has its own character — see our full guide to the best beaches in Hawaii.
Key West & the Florida Keys
At the end of the Overseas Highway, Key West is the quirky, colourful, sunset-loving southernmost point of the continental US, while the wider Florida Keys string tropical islands and coral reefs into turquoise waters. See our guide to the best beaches in Florida.
Sanibel & Amelia Island, Florida
Sanibel Island is world-famous for its shell-strewn beaches and unhurried, low-rise charm, while Amelia Island near the Georgia border pairs wide, uncrowded beaches with a genteel Victorian town — two of Florida’s most relaxing island escapes.
No-Passport Tropical Escapes: America’s Island Territories
Here is the best-kept secret in American travel: you can reach turquoise Caribbean water, powder-white sand and rum cocktails without ever pulling out a passport. As a U.S. citizen you can fly to these islands with nothing more than a government-issued ID, because they are U.S. territory — all the tropics, none of the customs lines.
The U.S. Virgin Islands: St. John, St. Thomas & St. Croix
The USVI are the crown jewels of passport-free travel. Fly into St. Thomas, then take the 20-minute ferry to tiny St. John, where Virgin Islands National Park protects more than 60% of the island — meaning beaches like Trunk Bay and Cinnamon Bay stay wild, with a marked underwater snorkeling trail (still recovering from the 2017 hurricanes) instead of high-rises. St. Thomas brings the shopping and nightlife; quieter St. Croix adds Danish colonial history and the underwater world of Buck Island. It is the easiest genuine Caribbean trip an American can take.
Puerto Rico’s Islands: Culebra & Vieques
Off Puerto Rico’s east coast sit two islands that regularly out-rank the mainland’s beaches. Culebra’s Flamenco Beach — a horseshoe of white sand behind a protecting reef — lands on world-best-beach lists year after year. Vieques counters with Mosquito Bay, the brightest bioluminescent bay on the planet, where every paddle stroke lights up the water electric blue. Reach both by a short ferry from Ceiba or a quick prop-plane hop from San Juan.
Guam and the Pacific Territories
For West Coast and Pacific travelers, Guam offers the same no-passport rule in a different ocean: Tumon Bay’s reef-sheltered lagoon, WWII history, and a Chamorro-Pacific culture found nowhere else in the U.S. Remote American Samoa, home to the only U.S. National Park south of the equator, rewards the truly adventurous, though it runs its own immigration: bring a passport and proof of onward travel.
| Destination | Getting there (from mainland) | Don’t miss | Best for |
|---|---|---|---|
| St. John, USVI | Fly to STT + 20-min ferry | Trunk Bay, national park trails | Beaches & snorkeling |
| St. Thomas, USVI | Direct flights | Magens Bay, duty-free shopping | Easy first Caribbean trip |
| Culebra, PR | Fly to SJU + ferry/prop plane | Flamenco Beach | World-class sand |
| Vieques, PR | Fly to SJU + ferry/prop plane | Bioluminescent Mosquito Bay | Once-in-a-lifetime nights |
| Guam | Long-haul flight (Pacific) | Tumon Bay, WWII sites | Pacific culture & reefs |
Island-hopping Hawaii is the other classic no-passport tropical trip — see our best beaches in Hawaii for where to land first.
Best US Islands for Every Kind of Traveller
- Classic New England charm: Nantucket, Martha’s Vineyard, Block Island.
- Step back in time (car-free): Mackinac Island, Bald Head Island.
- Tropical paradise: Kauai, Maui, Key West, the Florida Keys.
- Wildlife & the outdoors: the San Juan Islands (orcas), the Apostle Islands.
- Shelling & relaxed beaches: Sanibel, Amelia Island.
- Easy mainland escape: Catalina Island.
Car-Free Islands: Where to Leave the Keys Behind
A handful of American islands have made a deliberate choice to keep cars out — and they are consistently the ones travelers fall hardest for. Without engines and asphalt, the pace drops, the air clears, and a bicycle or a pair of walking shoes becomes all the transport you need. If you want a genuine escape, start here.
- Mackinac Island, Michigan — the icon. No cars since 1898; you travel by bike, horse-drawn carriage or on foot, past the Grand Hotel’s 660-foot porch and endless fudge shops.
- Bald Head Island, North Carolina — reached by ferry from Southport, explored entirely by golf cart and bicycle, with maritime forest and the state’s oldest lighthouse.
- Cumberland Island, Georgia — wild, ferry-only, and roamed by feral horses (see above).
- Fire Island, New York — a summer barrier island a train-and-ferry ride from Manhattan, where boardwalks replace roads.
- Monhegan Island, Maine — a rugged artists’ colony an hour offshore, all footpaths and sea cliffs.
- Daufuskie Island, South Carolina — Gullah heritage and golf-cart lanes, a boat ride from Hilton Head.
The trade-off is planning: you park on the mainland, pack light into a single bag or bike pannier, and surrender to island time. Nearly everyone who does it says the same thing on the ferry home — they wish they’d stayed longer.
| Island | Get around by | Ferry from |
|---|---|---|
| Mackinac, MI | Bike, carriage, foot | Mackinaw City / St. Ignace |
| Bald Head, NC | Golf cart, bike | Southport, NC |
| Cumberland, GA | Foot, bike | St. Marys, GA |
| Fire Island, NY | Boardwalk, foot | Bay Shore / Sayville, NY |
| Monhegan, ME | Foot only | Port Clyde / Boothbay, ME |

Best Time to Visit America's Islands
Summer (roughly June to September) is peak season for most US islands — the New England, Great Lakes and Pacific Northwest islands are only fully ‘in season’ then, with warm weather, ferries running and everything open (and busiest). Late spring and early fall are lovely shoulder windows with fewer crowds. The tropical islands (Hawaii and the Florida Keys) are year-round, though winter is peak escape-the-cold season there. Whatever the island, book ferries and lodging well ahead for summer, when the most popular escapes fill fast.
What an Island Trip Costs — and When to Go
Island trips carry a hidden premium: ferries, limited lodging and the cost of shipping everything across water all nudge prices up. Timing is the single biggest lever you can pull. Nearly every U.S. island runs a short, expensive summer peak and a shoulder season that is quieter, cheaper and often nicer.
| Season | Months | Crowds & prices | Best for |
|---|---|---|---|
| Peak | Jun–Aug (Dec–Apr in the tropics’ dry season) | Highest; ferries & inns book out | Warmest water, full services |
| Shoulder | May & Sep–Oct (North); Apr & Nov (tropics) | Moderate; noticeably cheaper | Best value, mild weather |
| Off | Nov–Apr (North) | Lowest; many places closed | Solitude, storm-watching |
Budget realistically for the crossing itself — a summer car ferry to Nantucket or the San Juans can run well over $100 round-trip, while foot-passenger fares are a fraction of that. On car-free islands you save on rental and gas but spend on carriage rides, bike hire or golf carts. Booking lodging months ahead for July and August is not optional on the popular islands; it is the difference between going and not.

Planning an Island Getaway
Most US islands are reached by ferry (Nantucket, the San Juans, Mackinac) or a short flight (Hawaii, Catalina), and many are wonderfully car-light or car-free, so you’ll get around on foot, by bike, golf cart or ferry. That makes timing and logistics — flights or ferries, where to stay, how many days — worth planning as a package. An AI trip planner can line up the whole island escape for your dates in about a minute.

Frequently Asked Questions
What is the most beautiful island in America?
It depends on your taste — Hawaii’s Kauai and Maui are the tropical icons, Nantucket and Martha’s Vineyard the New England classics, Mackinac the nostalgic car-free gem, and the San Juans the Pacific Northwest’s wild, orca-filled haven. Each is beautiful in a completely different way.
What US islands don’t require a passport?
All of them — every island in this guide is part of the United States, so US citizens need no passport, from Nantucket and Mackinac to Hawaii, Key West and the San Juans. (Puerto Rico and the US Virgin Islands, though in the Caribbean, are US territories and also need no passport.)
Which US islands are car-free?
Mackinac Island in Michigan has famously banned cars for over a century — you get around by bike, horse-drawn carriage or on foot. Bald Head Island in North Carolina is golf-cart-only, and islands like Nantucket are very walkable and bikeable, so many visitors skip a car entirely.
What is the best time to visit America’s islands?
Summer (June–September) is peak season for the New England, Great Lakes and Pacific Northwest islands, when ferries run and everything is open. Late spring and early fall are quieter shoulder windows. The tropical islands (Hawaii, the Florida Keys) are year-round, with winter as peak escape-the-cold season.
What is the best US island for wildlife?
The San Juan Islands in Washington are among the best places in the world to see orcas (killer whales), along with seals, eagles and porpoises. Hawaii offers whale watching and sea turtles, and Florida’s islands are great for manatees, dolphins and birdlife.
How do you get to America’s islands?
Most are reached by ferry (Nantucket, the San Juans, Mackinac, Block Island) or a short flight (Hawaii, Catalina, Key West by road or air). Many are car-free or car-light once you arrive, so you’ll get around on foot, by bike, golf cart or ferry.
Which US island has no cars?
Several. Mackinac Island in Michigan is the most famous — it has banned automobiles since 1898. Others include Bald Head Island (NC), Cumberland Island (GA), Fire Island (NY), Monhegan Island (ME) and Daufuskie Island (SC), where you get around by bike, golf cart, carriage or on foot.
What US islands can you visit without a passport?
Any U.S. state or territory. That includes Hawaii and all its islands, plus the tropical territories: the U.S. Virgin Islands (St. John, St. Thomas, St. Croix), Puerto Rico’s islands (Culebra and Vieques), and Guam. U.S. citizens travel there with a government-issued photo ID — no passport required.
Which US island has wild horses?
Assateague Island (Maryland and Virginia) is the best known, home to the wild ponies made famous by Misty of Chincoteague. Cumberland Island in Georgia has feral horses roaming its dunes and ruins, and Shackleford Banks in North Carolina’s Outer Banks has its own herd.
What is the most remote inhabited US island?
In the continental U.S., Tangier Island in Virginia’s Chesapeake Bay and Maine’s Monhegan Island are among the most isolated year-round communities. Far beyond them, American Samoa in the South Pacific is the most remote U.S. territory of all.
Which US island is best for a family vacation?
Car-free Mackinac Island tops many lists for its safety and novelty, while Florida’s shell-strewn Sanibel and Rhode Island’s compact, bike-friendly Block Island are easy, gentle choices for younger kids.
How safe is swimming at America's island beaches?
Less safe than the postcards suggest, and worth planning around. Most US island beaches have no lifeguard at all, and rip currents are the main hazard on open ocean coasts from the Outer Banks to the Gulf and the Pacific. Hawaii is the serious case: state health and ocean safety figures show drowning as a leading cause of injury death among visitors there, with most ocean drownings happening at unguarded beaches and visitors making up a large share of the total. Swim at a guarded beach where one exists, read the posted flags, ask a lifeguard about the day’s conditions, and never swim alone. If a current takes you, swim parallel to the shore rather than against it.
When is hurricane season, and which islands does it affect?
The Atlantic hurricane season officially runs from 1 June to 30 November, with activity concentrated in late August, September and October. It covers the Florida Keys, the East Coast barrier islands, Puerto Rico’s islands and the US Virgin Islands. Hawaii has its own Central Pacific season over broadly the same months, though direct strikes there are rarer, and the northern islands, the Great Lakes and the Pacific Northwest sit outside it entirely. Travelling within the window is not unreasonable, since prices fall and it is often quiet, but book refundable where you can, choose insurance that covers named storms, and follow the National Weather Service’s hurricane advisories rather than a general forecast in the days before you fly.
How much should you budget for a US island trip?
More than the same trip on the mainland, because nearly everything has to cross water. Expect a premium on lodging, groceries and eating out, plus a real cost for the crossing itself: summer car ferries to the popular New England and Pacific Northwest islands run to a substantial fare, while foot passengers pay a fraction of that. On car-free islands you save on fuel and hire but spend on bicycles, golf carts or carriages. Timing is the biggest lever you have, since the peak is short and expensive and a shoulder-season week is materially cheaper and often nicer. Leaving the car on the mainland and crossing on foot with a bike is the easiest single saving.
Is a long weekend enough for an island trip?
It depends on how hard the island is to reach. The near-mainland ferry islands of New England and the Great Lakes work well as two or three nights, enough to cycle the whole thing, eat properly and still have one slow morning. Give the wilder ferry-only islands at least two nights, since a day trip is governed by the boat timetable and half of it goes on travelling. Hawaii deserves a week at minimum, and more if you intend to see two islands rather than one. Whatever you choose, add a buffer night at the end rather than connecting a ferry straight to a flight, because crossings are cancelled for weather more often than people expect.
Final Thoughts: Choosing Your American Island Escape
From cobblestoned New England harbours to tropical Hawaiian shores, America’s islands prove you don’t need to leave the country to find paradise. Choose Nantucket or Mackinac for nostalgic charm, the San Juans for orcas and wilderness, Catalina for an easy escape, or Hawaii and the Keys for full tropical splendour. Match the island to your mood, visit in summer (or year-round for the tropics), book ferries and lodging ahead, and embrace the slower, car-free island pace. Do that, and your American island getaway will feel a world away.
