Lushly carpeted in tropical forest, St. John is largely protected as a national park, making the U.S. territory an eco-lover's island. There's only one significant town, Cruz Bay, and countless inviting coves and hills to explore.
Budget travel tip At the earth-minded Maho Bay Camps canvas-roofed platform cottages (which look like glorified tents) sit right above the beach and go for $75 per night (800-392-9004, maho.org). Guests share centralized bathhouses in the complex built on hillside pillars to prevent erosion.
Get moving! Follow the do-it-yourself snorkeling "trail" with submerged signposts in Trunk Bay, a protected marine reserve (call 340-776-6201 for info).
Can't miss Park rangers lead guided hikes down the 2.5-mile Reef Bay trail deep into the forest, ending with a dip in the waters of a remote south-shore beach. The outing fills up fast, so reserve in advance ($42 for transportation; 340-776-6201, nps.gov/viis).
Pamper yourself Lodged in an isolated hilltop bungalow, the Self Centre at the upscale Caneel Bay resort offers mind-body workshops that include Breathwalk sessions, meditation and partner yoga beginning at $35 (340-776-6111, caneelbay.com/selfcentre.cfm).
