Desolation Peak Trail
What to Expect
Safety Advisory
The upper two-thirds of the trail is fully exposed with no shade or shelter — lightning is a serious risk during afternoon storms from July through September. Turn back if dark clouds build.
Snow can linger on the upper slopes well into July, making route-finding difficult and footing treacherous. Check recent trip reports before committing to this one early in the season.

Pro Tips
You'll need to arrange the Ross Lake Resort water taxi to reach the trailhead at the east side of the lake — book well in advance for summer weekends, and confirm pickup times so you're not stranded.
Start early to tackle the exposed upper section before afternoon heat and thunderstorms roll in. Carry at least three liters of water — there are no reliable water sources on the climb itself.
The lookout cabin is one of the most photogenic spots in the North Cascades. Golden hour light on Hozomeen's twin summits is extraordinary, and if you're backpacking, camping near the summit for sunrise is worth the extra weight.
