Desolation Peak Trail

Overview

This is the classic grind to a historic 1932 fire lookout perched above Ross Lake. Expect a sustained, no‑nonsense climb that trades sweat for some of the best views in the range—Hozomeen looming close, Jack Mountain with the Nohokomeen Glacier, and a horizon crowded with North Cascades peaks. The lookout is typically staffed in summer (it’s not a public rental and the structure itself is not open to enter), which adds a living‑history vibe and a little Kerouac lore to the experience.

Distance, Elevation, and Route

From the Lightning Creek/Desolation boat dock, it’s about 9.4 miles round trip with roughly 4,400–4,540 feet of gain, out‑and‑back to the summit. The grade is consistent with little relief, starting in forest and climbing into subalpine terrain with ever‑expanding views over Ross Lake. If you choose to walk in entirely on foot via the East Bank Trail from Highway 20, you’re committing to a roughly 44–46 mile round‑trip backpack—rewarding but serious.

What You’ll See

Views are the headline: a 360‑degree panorama that puts Hozomeen and Jack Mountain front and center, with Ross Lake unfurling below and far‑flung summits like Logan, Buckner, Boston, Torment, and Eldorado lining the skyline. On clear days you can see into Canada. The route transitions from old‑growth forest to airy subalpine slopes, and late‑season hikes can deliver punchy fall colors.

Access and Logistics

Most hikers reach the trailhead by arranging the Ross Lake Resort water taxi (about a 1‑mile walk from Highway 20 to the taxi dock). Paddlers can approach from Colonial Creek on Diablo Lake (portage required to Ross Lake) or from Hozomeen to the north (no portage). Ross often builds strong afternoon winds and whitecaps, and the water stays very cold, so start early and plan conservatively. A full foot approach via the East Bank Trail is possible but long. No camping is allowed on the summit; the closest designated site is Desolation Camp about a mile below the top. Backcountry permits are required for Desolation Camp and all Ross Lake boat‑in camps.

Difficulty and Conditions

This hike is strenuous. The grade is steady, the elevation gain is big, and the trail is often hot and dry—carry more water than you think you’ll need. Late June can hold short snow patches near the summit. Summer brings the best odds for dry trail and staffed‑lookout vibes, but be alert for afternoon thunderstorms and occasional wildfire smoke in late summer.

Best Time to Hike

Summer through early fall is prime. Aim for an early start for cooler temps, calmer lake conditions if you’re boating, and softer morning light on Hozomeen and Jack. September often balances clear air, stable weather, and lighter crowds; early fall color sweetens the climb. Weekdays help if you’re trying to snag permits and taxi reservations.

Tips

• Arrange water taxi logistics in advance and be punctual at the dock.
• Carry ample water; reliable sources are scarce once you’re climbing.
• If paddling, dress for very cold water and plan for afternoon winds.
• Don’t expect to enter the lookout; enjoy the site, ranger chat (if staffed), and the views.
• Dogs are not allowed on this National Park trail, even if they can ride the taxi.
