When most Americans dream of island getaways, their minds often drift to Caribbean beaches or Hawaiian shores. Yet the United States boasts numerous stunning island destinations that remain surprisingly under the radar despite offering extraordinary natural beauty, unique cultural experiences, and the special magic that comes from being surrounded by water.
These hidden gems provide all the escapism of an island vacation without the crowds, high prices, or long international flights. Here is a list of 15 underrated U.S. island destinations that deliver unexpected delights for travelers willing to venture beyond the obvious choices.
Daufuskie Island, South Carolina
Accessible only by boat, this sea island between Savannah and Hilton Head preserves a distinctive Gullah culture and way of life that has been largely unchanged for generations. Unpaved roads wind past live oak trees draped with Spanish moss, connecting a small community of artists, writers, and longtime residents whose families have called the island home since the 1700s.
The absence of bridges means few cars, creating a peaceful environment where travelers explore via golf cart, bicycle, or on foot past historic landmarks, including First Union African Baptist Church and the two-room schoolhouse where author Pat Conroy once taught.
Monhegan Island, Maine
Rising dramatically from the Atlantic about 10 miles from the mainland, this rugged outpost has attracted artists for over a century with its extraordinary quality of light and dramatic landscapes. Seventeen miles of hiking trails cross the largely undeveloped island, leading to 160-foot sea cliffs that rank among the highest on the Eastern Seaboard.
The year-round population of about 65 swells during summer months, yet the island maintains its authentic character with no cars, no paved roads, and limited amenities that include a single brewery housed in the island’s former schoolhouse.
Tangier Island, Virginia
This isolated Chesapeake Bay community offers a journey not just across water but seemingly through time. Residents speak a distinctive dialect dating back to their 17th-century English ancestors, creating what linguists consider one of the most unique accent patterns in America.
The island’s narrow streets accommodate mainly golf carts and bicycles, passing modest homes where families have worked the surrounding waters as watermen for generations. Fresh blue crabs feature prominently on local menus, while guides explain how rising sea levels threaten this remarkable cultural enclave that sits just four feet above high tide.

Local restaurants serve traditional fish boils—a regional specialty where whitefish from surrounding waters is cooked outdoors in large kettles over open flames. Five shipwrecks surrounding the island create exceptional diving opportunities in the clear, fresh water of Lake Michigan.
Dauphin Island, Alabama
This barrier island near Mobile offers miles of uncrowded white-sand beaches alongside exceptional birdwatching opportunities. The Audubon Bird Sanctuary covers 164 acres of protected maritime forest, marshes, and dunes, serving as the first landfall for many migratory species crossing the Gulf of Mexico each spring.
Historic Fort Gaines, with walls over 150 years old, stands guard at the eastern end of the island, where visitors can explore casements, tunnels, and blacksmith demonstrations. The island’s laid-back atmosphere provides a refreshing alternative to the more developed Gulf Coast destinations just a short drive away.
Smith Island, Maryland
This Chesapeake Bay community can only be reached by boat, preserving a distinctive culture and dialect among watermen who have harvested blue crabs and oysters for generations.

The Johnson Farm museum complex preserves buildings from the 1800s, offering insights into pioneer life in this corner of the Pacific Northwest.
Isle au Haut, Maine
Half of this rugged island belongs to Acadia National Park, yet it receives just a fraction of the visitors who crowd the park’s main section on Mount Desert Island. A mail boat provides the only public transportation to the island, delivering both passengers and supplies to the community of approximately 70 year-round residents.
Miles of hiking trails cross remote terrain, leading to scenic overlooks and secluded coves where visitors might spot seals, porpoises, and a variety of seabirds. The island’s only store stocks freshly baked bread alongside fishing supplies, embodying the practical approach to life in this remote community.
Middle Bass Island, Ohio
The peaceful middle sibling of Ohio’s Lake Erie islands offers a relaxed alternative to the more boisterous Put-in-Bay on nearby South Bass Island. Visitors can tour the historic Lonz Winery, recently renovated into a state park pavilion that preserves the stone facade of what was once the largest winery in America.
The island’s gentle terrain makes for easy exploration by bicycle, passing vineyards, historic homes, and lakefront parks. A small marina welcomes private boats, while the Sonny-S ferry brings day-trippers and weekenders seeking a quieter Lake Erie experience.

The island preserves its Irish heritage through music, storytelling, and community celebrations that reflect the cultural backgrounds of settlers who arrived after the Mormon community disbanded.
Six inland lakes provide additional water recreation beyond the Lake Michigan beaches, while dark night skies offer remarkable stargazing opportunities. The remote location—32 miles from the mainland—creates a genuine island atmosphere, unlike more accessible Great Lakes destinations.
Isle Royale, Michigan
This isolated national park in Lake Superior closes completely during winter, creating one of America’s least-visited national parks despite its extraordinary wilderness value. The island’s wolves and moose have been studied continuously since 1958 in the longest-running predator-prey research project in the world.
No roads cross the island, meaning visitors explore exclusively by foot along 165 miles of hiking trails or by watercraft, navigating the scenic coastline. Reaching the island requires planning, as visitor services operate only from May through October, with transportation limited to seaplane or ferry from Michigan or Minnesota.
