Reef Bay Trail
Fodor's choice
This is one of the most interesting hikes on St. John, but it's only for the physically fit as the 2-mile return climb, rising 900 feet from sea level back to the trailhead, is a real workout. Along the way, one short side trail to the west takes you to a small pool where indigenous inhabitants carved petroglyphs into the rock. Another short side trail to the east leads to the plantation's greathouse, a gutted but mostly intact structure with vestiges of its former beauty. Down at sea level, walk around the sugar factory ruins. The beach here makes a great place to cool off before hiking back up. Difficult.
