Maine's Acadia National Park, on Mount Desert Island, evokes all the romanticism of New England. Rugged coastlines provide spectacular ocean views, with lobster boats and osprey greeting from the water. Tidal pools beg exploration. The 20-mile Park Loop Road passes the most popular sites, including Jordan Pond and Cadillac Mountain. John D. Rockefeller built 57 miles of roads for carriages, and today they are the perfect terrain for exploring Acadia by bike, foot, horse, snow shoe or cross country ski.
