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. A trip into the Flume begins and ends at the Flume Visitor’s Center. Guests can choose to walk through just the Gorge or do a two mile loop. 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.
