Dunraven Pass – Mount Washburn Trail

About This Trail

Mount Washburn is a strenuous alpine hike that delivers 360-degree views and an active fire lookout at the summit. The 6-mile round-trip ascent rewards effort with panoramic vistas, bighorn sheep, and alpine wildflowers. Expect serious physical challenge, zero water access, lightning hazard above treeline, and grizzlies in fall seeking whitebark pine nuts. Mandatory: hike in groups of 3+, make constant noise, carry bear spray, and summit before afternoon electrical storms form.

Highlights

Insider Tips

• Hike in tight groups of 3+ and make constant noise—required for bear safety in this area • Bring 2-3 liters of water; there are zero sources along the entire trail • Carry bear spray rated for Yellowstone grizzlies and verify functionality • Start before 6 AM to summit and descend before afternoon lightning storms develop • Sunscreen, hat, and UV-blocking sunglasses are non-negotiable at this altitude • If lightning appears or thunder audible, descend immediately—absolutely non-negotiable • This hike is unsuitable for anyone with documented cardiac or respiratory problems per NPS

Best Season to Hike

Summer and Fall

Family Info

Not family-friendly. High elevation causes breathing difficulty. Lightning above treeline, grizzly bears in fall, zero water, and steep exposed sections make this unsuitable for young children. NPS specifically advises against this hike for anyone with documented cardiac or respiratory conditions.

What Hikers Say

Hikers consistently report this is a relentless altitude climb rewarded by summit views and an active fire lookout shelter. The lack of water, exposure to lightning, and seasonal grizzly bears demand serious preparation and fitness—this is not a casual walk or suitable for untrained hikers.
