Although the terrain is pretty rugged, two tour operators have put together fascinating bicycle and combination bicycle-hiking tours that appeal to novice riders as well as those who enjoy a good workout. Prices range from $60 to $100 per person. Bike St. Lucia (Anse Chastanet, Soufrière. 758/451-2453. www.bikestlucia.com) takes small groups of bikers on Jungle Biking™ tours along trails that meander through the remnants of an 18th-century plantation near Soufrière. Stops are made to explore the French colonial ruins, study the beautiful tropical plants and fruit trees, enjoy a picnic lunch, and take a dip in a river swimming hole or a swim at the beach. If you're staying in the north, you can get a tour that includes transportation to the Soufrière area. Island Bike Hikes (Castries. 758/458-0908. www.cyclestlucia.com) is suitable for all fitness levels. Jeep or bus transportation is provided across the central mountains to Dennery, on the east coast. After a 3-mi (5-km) ride through the countryside, bikes are exchanged for shoe leather. The short hike into the rain forest ends with a picnic and a refreshing swim next to a sparkling waterfall -- then the return leg to Dennery. All gear is supplied.
