Acadia National Park has 45 miles of unpaved carriage roads dating from the early 20th century. Built by philanthropist John D. Rockefeller, Jr., these rustic pathways meandering over Mount Desert Island were intended for horse and carriage rides. Today they are used by park visitors for hiking, horseback riding and bicycling. Along the way, one is likely to discover beautiful sights in the mountains and valleys, such as this gem of a waterfall, right next to the carriage road.
