Arc Dome Wilderness, Protected wilderness area in Nye County, Nevada, United States

Arc Dome Wilderness is a protected region spanning approximately 115,000 acres across the Toiyabe Range, with mountain peaks, valleys, and distinct ecological zones at different elevations. The terrain rises across considerable elevation changes and displays shifting habitats ranging from dry sagebrush areas to forested slopes.

The area received protection from the United States Congress in 1989 and became part of the Humboldt-Toiyabe National Forest system. This designation reflects a growing recognition of the importance of undeveloped mountain landscapes for nature conservation and recreation.

The name comes from Arc Dome, the 3,591-metre summit of the Toiyabe Range that the wilderness surrounds. The 116-kilometre Toiyabe Crest Trail is designated a National Recreation Trail and follows the ridge, with 48 kilometres inside the wilderness; the Cow Canyon Trail is also maintained. Trekking, climbing, fishing, hunting and stargazing are permitted, but motorised transport and mountain bikes are not.

Visitors should bring sufficient water, navigation tools, and emergency supplies because this area lacks developed facilities or marked trails. Proper preparation is essential when traveling through this undeveloped terrain.

The wilderness takes its name from Arc Dome, the 3,591-metre summit of the Toiyabe Range, which rises inside the protected area. The Toiyabe Crest Trail runs 116 km along the ridge, and 48 km of it lie within the wilderness. Motorised transport and mountain bikes are not allowed.
