Difficulty: Easy to strenuous, depending on your route. Acadia National Park on Mount Desert Island is home to about 45 miles of carriage roads that intersect in many places, forming a multitude of possible bike routes. The roads are 16 feet wide, smooth and surfaced with crushed rock. Some sections are hillier than others.

Information: Winding through the forest around mountains and ponds, the carriage roads of Acadia National Park are a great way to explore the park by bicycle. These wide, smooth roads are closed to motorized vehicles (with a few exceptions). They feature massive historic stone bridges and lead to some incredible views of Mount Desert Island.
