FORGET THE BEACHES. The mountain biking on St. Lucia has visitors looking inland, where riders can rip past waterfalls and saman trees on dozens of singletrack trails and fire roads throughout the 238-square-mile island. The best riding is in the 400-acre Anse Mamin Plantation's 12-mile network of jungle-lined track, dedicated solely to knobby tires. Suitable for a range of abilities, the trails wind through the old sugarcane fields and offer opportunities for freeriders to drop some of the plantation's original stone walls and stairways. The biggest challenge? The two-mile Tinker Juarez Trail, designed by the endurance mountain biker and two-time Olympian. This climb to the top of a 900-foot peak has been completed only once sans hiking, by Tinker himself.
