Big Lost River Access Trail

This 2.5 - 3 mile trail has been a community effort. Please respect the adjacent private property by staying on the trail and using non-motorized means to get to the river. For motorized recreationists, the old road from here up Blaze Canyon to the Windy Devil communication tower is a designated off-highway vehicle (OHV) trail. There is typically cell service at this site.
