About 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.

How to Get There

Approximately 1 mile northwest of Mackay, Idaho along the Big Lost River. Turn west off of Hwy. 93 onto Main St. in Mackay. Continue south; Main Street turns into Smelter Road and crosses the Big Lost River (there is a signed IDF&G public river access on the southeast side of the bridge). Proceed approximately 1 mile, cross the cattleguard and turn right. Follow this road approximately 2 miles to the signed day use parking area for the Big Lost River Access Trail, located on the north side of the road.
