The trail to Big Bradley Falls is part of an unmarked, untended section of the Green River Game Lands - a rugged, 10,000 acre tract of land owned by the state for hunting and fishing. Hike at your own risk - the trail is primitive and requires crossing the stream. Proper hiking shoes required. The trail is especially dangerous at the top of the falls. Do not attempt to hike to the bottom. Please call the Polk County Visitor Center for more info at (800)440-7848.
