Carriage Path Trails, Bar Harbor, Maine
Off limits to motorized vehicles, these wide, hard-packed gravel trails lead bikers to some of the most secluded parts of the park. The 43-mile network is ideal for inexperienced mountain bikers. Start by circling the shores of Eagle Lake, Acadia’s second largest body of water. Under a forest of spruce, you steadily climb counterclockwise, only to coast downhill when Cadillac Mountain dramatically comes into view. Far more remote is the Amphitheater Loop, used primarily by local dog walkers. Park your car at the Brown Mountain Gate House off Route 198 and begin to pedal uphill, quickly getting glimpses of the ever-present Atlantic. The 4.4-mile loop is a magical up and down run through the dense woods. A highlight is the chance to ride across the Amphitheater Bridge, the longest of John D. Rockefeller’s original overpasses. www.nps.gov/acad/index.htm.
