Overview
Arc Dome stands at 11,773 feet at the southern end of the Toiyabe Range in central Nevada, the highest point of a mountain range rising from a desert floor at 5,500 feet. The summit is the focal point of the Arc Dome Wilderness, 115,000 acres of roadless terrain in Humboldt-Toiyabe National Forest that qualifies as genuinely remote by any standard: the nearest significant services are 90 miles away, cell service is nonexistent for the entire approach, and the route to the summit sees a fraction of the foot traffic of comparable peaks in the Sierra Nevada or Colorado Rockies.
The 16-mile out-and-back follows the Toiyabe Crest Trail from the Stewart Creek Trailhead, gaining 4,700 feet across a route that climbs through aspen groves, montane meadows, limber pine forest, and open ridgeline before reaching the broad, rocky summit. The views from the top are unlike anything achievable in more-visited mountain landscapes: the Great Basin's parallel ranges and valleys stretch in every direction to a flat, hazy horizon, a landscape that feels more like a vast inland sea than a mountain environment.
This is one of the two or three hardest day hikes in Humboldt-Toiyabe National Forest. The 4,700-foot gain and 16-mile distance put it in a category requiring serious preparation. Many visitors treat this as an overnight backpacking trip, camping in the arc of high terrain south of the summit and completing the final push on day two.

The Route
Miles 0 to 3.0 (Lower Toiyabe Crest Trail): The trail begins at the Stewart Creek Trailhead at approximately 7,100 feet and climbs steadily through sagebrush and mountain mahogany. The lower sections are exposed and warm in summer but the gradient is manageable. The Toiyabe Range's structure becomes visible as the trail gains elevation: a long ridge running north-south, with Arc Dome visible ahead on clear days.
Miles 3.0 to 6.0 (Crest Trail to Subalpine Zone): The trail follows the crest of the Toiyabe Range, alternating between the west and east sides of the ridge with views into the desert valleys on both sides. The vegetation transitions to aspen groves and mountain meadows in the protected drainages. Several seasonal springs cross the trail.
Miles 6.0 to 8.0 (Summit Approach): The final 2 miles climb into the arc-shaped high terrain that gives the peak its name. The summit dome becomes the dominant feature. The trail is marked with cairns in the upper sections but is indistinct on open rocky terrain. A topographic map and GPS are recommended.
The Summit: The 360-degree view from Arc Dome spans the full Great Basin. The Toiyabe Range drops away in both directions. The Monitor, Toquima, and Shoshone ranges are visible to the east. The Sierra Nevada is visible on the western horizon on very clear days.
When to Visit
July through September. Snow typically remains on the crest trail until late June. Afternoon thunderstorms are a daily risk from late June through August; the exposed ridge sections make shelter impossible. Plan to reach the summit before noon and begin the descent before early afternoon.
Check weather forecasts for central Nevada and conditions at the Stewart Creek Trailhead before any visit via our pre-trip resources guide.
What to Bring
Many hikers carry 3 to 4 liters for this demanding route, with resupply possible at seasonal springs on the crest trail. Individual needs vary significantly; the high desert climate and sustained effort mean hydration needs are higher than comparable routes at similar elevations in the Sierra Nevada.
Consider bringing:
- Topographic map and GPS for the summit approach
- Wind and rain protection for the exposed crest sections
- Trekking poles for the sustained 4,700-foot climb and descent
- Extra food for a hike of this length and difficulty
- Headlamp if an early start or late return is possible
Practical Details
No permit required (as of 2026). Free campfire permit for any open fire. Dogs allowed on leash. High-clearance vehicle recommended for the approach road. No facilities at the trailhead.
Veterans should review our veteran benefits guide for applicable national forest access benefits.
Getting There
From Austin on US Route 50, drive south on Stewart Creek Road approximately 12 miles to the Toiyabe Crest Trailhead. Austin is approximately 170 miles east of Reno via US Route 50. The road to the trailhead becomes a gravel forest road and requires a high-clearance vehicle for the final miles. Austin is the last place for fuel and basic services before the trailhead. Download offline maps and a weather forecast before leaving Austin. Cell service is absent from the Austin outskirts to the trailhead.
