11 U.S. Islands You Can Visit Without Passport

Puerto Rico

Tall palm palms, blue lakes, and old mountains wrapped in lush flora make Puerto Rico a tropical paradise. It's ideal for lounging on some of the nation's nicest beaches with a piña colada.

Daufuskie Island, South Carolina

Daufuskie Island, about an hour's boat trip from the South Carolina mainland, feels worlds apart. While dolphins splash and alligators peek out of deep green lagoons, sandy beaches extend for miles.

Assateague Island, Maryland

A fun day or weekend trip for beach-goers, hikers, and kayakers, you can stay in lodging outside the island and visit for the day, or camp at one of the island's beach- or sound-side campsites.

San Juan Islands, Washington

Seals sunbathe on San Juan Island, whales swim offshore, and bald eagles fly overhead. Friday Harbor is a lovely village with stores, galleries, and great restaurants.

The U.S. Virgin Islands

On St. Croix, the largest of the three islands, an ideal day includes walking on white-sand beaches, diving at Buck Island Reef National Monument, and exploring colonial-era churches before watching the sunset at one of the numerous romantic restaurants. Fresh fish abounds here.

Mackinac Island, Michigan

The island's Victorian, Colonial, and early Indigenous architecture spans three centuries. It's one of the nation's most unusual vacation spots, whether you hike, kayak, or visit one of the island's fudge shops on Main Street.

Coronado Island, California

Coronado Island, a gorgeous island in San Diego, is easily accessible by bridge, boat, or water taxi. The gentle, white beaches provide spectacular vistas of San Diego. 

Washington Island, Wisconsin

Lake Michigan appears to dissolve into the light in Door County, Wisconsin. It's clear why this Great Lakes area is called the "Cape Cod of the Midwest."

Bald Head Island, North Carolina

Ferries to Bald Head Island take 20 minutes. Islanders use bicycles, golf carts, and trams because cars are banned. Old Baldy, North Carolina's oldest lighthouse, offers great views.

Isle Royale, Michigan

A national park on Lake Superior, it is essentially underdeveloped. It's a hiking, kayaking, canoeing, and backpacking heaven. You may take an aircraft or a ferry to the island.

Amelia Island, Florida

The Amelia Island Historic District is one of the state's most picturesque little towns, with colorful Victorian architecture and historic buildings, many of which are now Bed & Breakfasts.
