The National Recreation Toiyabe Crest Trail runs through the Humboldt-Toiyabe National Forest in the Toiyabe Range, consisting of over 70 miles of trail atop the ridge, 30 miles of which travel through the Arc Dome Wilderness.[4] The Army Corps of Engineers constructed the trail and its many "feeder" trails in the 1930s.[5] It travels through one of the longest roadless areas in the state,[6] and sits atop the longest mountain range in Nevada at over 120 miles long.
