One of the great beauties of the United States is its immense diversity, which means that you can easily travel to destinations that seem a million miles away from your hometown. It is estimated that there’s about 150 islands with an area of 20 square miles or greater in the U.S. (not including territories such as Puerto Rico and the U.S. Virgin Islands). If you are looking for an island getaway without having to get out your passport then the following could be for you.
Block Island, Rhode Island

Slow things down amid the New England charm of Block Island, just a short boat ride from mainland Rhode Island. Start in New Shoreham, where lunch at waterfront restaurants and shopping at the boutique-lined streets of the Old Harbour District is the order of the day. Then jump on a bike or moped to explore the island’s natural wonders. You’ll find quiet beaches, popular surf spots, and dramatic cliffs such as Mohegan Bluffs. Visit the picturesque lighthouses and hike coastal trails. Bird lovers relish in the opportunity to spot owls, songbirds, and waterfowl, among other species at Block Island National Wildlife Refuge.
