Stunning, shimmering sunsets across the water, the peaceful lullaby of waves crashing and the wind blowing, the feeling of truly being removed for your everyday life... yep, islands are pretty much the best. While it's wonderful to get that coveted passport stamp, there are plenty of islands to escape to that don't require a passport.
Here are 15 of our favorites.
NORTHEAST
Mount Desert Island, Maine
Home to Acadia National Park and the historic, upscale town of Bar Harbor, Mount Desert Island is 108 square miles of rocky coastlines, evergreen forests and crystal-clear lakes, not to mention some of America's oldest luxuries.

One third of the tiny island is owned by the Nature Conservancy to protect its natural marshlands, and it is full of nature and bird-watching trails. The rest of the island boasts some of the oldest buildings in America. Shelter Island Heights is officially recognized on the National Register of Historic Places for its collection of rural residences that have remained essentially unchanged since 1872.
