Push through a climb, sprint down slopes on a singletrack, or take a mellow ride through the deep woods. Whatever your speed on two wheels, Maine has outstanding mountain biking. Rent a bike from the Sugarloaf Outdoor Center and chart a course on the Carrabassett Valley Trail System, an extensive network of trails for beginners to experts. Or bike hut-to-hut on the year-round Maine Huts & Trails system and rest in front of the cozy fireplace at an eco-lodge. For downhill thrills on interconnected mountain peaks, Sunday River Bike Park offers challenging terrain and chairlift service, or meander along the Androscoggin River in Bethel for a more mellow ride.
