Sure, it’s the largest town on St. Croix, but it’s the charming Danish-influenced architecture that makes it most noteworthy. The city center is a protected national park lined with candy-colored buildings and historic churches, while the streets are made of cobblestones and punctuated by stone archways. At the waterfront, which was a focal point of the island’s sugar trade, a wharf is populated by restaurants, bars and water sports shops. There’s also an 18th-century fort.
