Acadia National Park defends the natural exquisiteness of the highest rocky headlands along the Atlantic shoreline of the U.S., a profusion of habitats, high biodiversity, fresh air and water, and a wealthy cultural legacy. Acadia National Park, an archipelago of islands, covers approximately 50 square miles and chances for hiking abound. The longest hike is up Cadillac Mountain, whose peak at 1,530 feet is the highest point along the North Atlantic seaboard. Try rock climbing and rappelling in one of numerous locations in the park, like Otter Cliffs, a sheer rock face overlooking the ocean. Riding along the 27-mile Park Loop Road is the finest way to do a quick trip of Acadia. Travel around the attractive Jordan Pond, a serene lake flanked by mountains.
