The 4.4 mile (one-way) Flat Top Trail was designated with Fallingwater Cascades trail as a continuous National Recreation Trail in April 1982. Flat Top rises to an elevation of 4,004 feet with many scattered rock outcrops. The Pinnacle and Cross Rock are names given to such formations. On this trail, hikers can experience the changing forest ecology as they climb or descend 1,600 feet from the Parkway trail heads. Strenuous. This hike will take the better part of a day to complete. Please plan accordingly. Tip: Because of the strenuous nature of this trail, hikers intending to complete the one-way distance may find it useful to leave one vehicle at the trail’s terminus (just a few miles south) at the Peaks of Otter picnic area and shuttle back in a separate vehicle to this trailhead.
