The Flume is a natural gorge extending 800 feet at the base of Mount Liberty. The walls of Conway granite rise to a height of 70 to 90 feet and are 12 to 20 feet apart. The Flume Trail is a 2-mile loop starting at the check-in booths located in front of the Flume Building. The entire loop takes approximately 1.5 hours and finishes at the Flume Building. The walk includes uphill walking and lots of stairs. The boardwalk allows you to look closely at the growth of flowers, ferns and mosses found here.
