3. Isle Au Haut, Maine, USA
Located 17 miles off Maine's rocky coast in Penobscot Bay, half the island is protected as part of Acadia National Park.
Thanks to its remote location, Isle au Haut is the perfect place to soak in the slow pace of Maine island life.
Even in high season when much of the Maine seaboard is awash with tourists, Isle au Haut feels delightfully untouched.
The small number of visitors (only about 7,000 annually) can camp overnight at Duck Harbor or come on a day trip on a scenic lighthouse cruise around the bay.
Here you can catch lobster with local fishermen, sea kayak, and walk on 18 miles of hiking trails.
