9. Acadia National Park, Maine
The Sargent Mountain Loop will take you from an elevation of 200 feet at Jordan Pond House to 1,373 feet at the summit of Sargent Mountain. The hike is not for those who are afraid of heights as hikers have to walk along steep cliffs. But the view from the top is well worth the harrowing journey. You have breathtaking views of the park and the coast. The trail is a moderate day hike and it’s 5.5 miles round trip.
