Virgin Islands National Park, U.S.V.I.
More than half of the island of St. John is preserved by the U.S. National Park Service, leaving visitors with unspoiled beaches, lush forests and historic sites (such as old sugar cane mills) to explore. You can drive through the park, making stops along the way, or opt for a bus tour. Don’t pass up a chance to go snorkeling when you visit—the Underwater Trail in Trunk Bay is good for beginners, while Maho Bay is a great place to spot sea turtles. The most luxurious place to stay is Caneel Bay Resort, located within the national park.
