Sahale Glacier Camp via Cascade Pass

North Cascades National Park, end of Cascade River Road (east of Marblemount)

Check before you go. Check before you go: a wildfire-tracker site summarizing park alerts (More Than Just Parks, Oct. 11, 2026) said Cascade River Road would close to vehicles at milepost 20 starting Oct. 13 for road maintenance. The park's own road-conditions page (updated July 3, 2026) listed the road as open, and its Cascade River Road page says foot and bike traffic are allowed past the gate. NPS says walk-up permits for Cascade Pass must be picked up in person during the season. The park's Wilderness Information Center in Marblemount closed for the season Oct. 11, 2026; NPS says self-issue permits are available outside it during the winter closure, or you can submit a permit by email following the steps on the park's permits page (updated Oct. 15, 2026). Self-issue permits are valid only while the center is closed; it reopens in mid-May 2027. Expect snow at camp by fall.

Sahale Glacier Camp sits at the top of Sahale Arm, a ridge that climbs from Cascade Pass toward Sahale Peak in North Cascades National Park. The Park Service lists it as a designated campsite at the toe of the glacier, 5.9 miles from the Cascade Pass trailhead.

Backpacker included it in a 2016 list of top national park campsites, calling it “high-alpine camping at its finest.”

The hike

The trailhead is at the end of Cascade River Road, about 23 miles from Highway 20 at Marblemount, according to The Mandagies’ guide. The Park Service says the road usually opens to the trailhead parking area by the end of June, or in early July after heavy snow years.

The Cascade Pass Trail climbs 1,700 feet in 3.7 miles to the pass (NPS). The Mandagies count the first 35 switchbacks at about 1,700 feet and describe stone benches at the pass, where most day hikers turn around. NPS doesn’t allow camping directly at Cascade Pass.

From the pass, the Sahale Arm Trail climbs toward the toe of the Sahale Glacier. The Mandagies describe alpine meadows of wildflowers and heather along the arm, with Doubtful Lake visible below, and a final steep, rocky, muddy stretch of about a fifth of a mile where boulders sometimes take hands and feet. NPS lists 3,940 feet of gain from the trailhead to the glacier and rates it strenuous.

At camp, rock-ring walls give some shelter from wind (The Mandagies), and Backpacker describes sleeping at the edge of the glacier with views of surrounding peaks and ice falling from glaciers below. The glacier above camp is climbing terrain for parties with crampons, ice axes and ropes, Backpacker notes.

The Park Service warns of steep snow sections that may need an ice axe as late as July, falling ice from the hanging glaciers on Johannesburg Mountain, and very fragile vegetation; it asks hikers to stay on trails, snow or rock. The Mandagies add bears and mountain goats, strong sun at altitude, and a warning not to dump greywater, since it can draw goats.

Past Cascade Pass, the trail continues east 9 miles to Cottonwood Camp, with other camps on the way toward Stehekin. NPS lists Pelton Basin, Basin Creek and Johannesburg camps nearby.

Tips

Pick up walk-up permits in person. NPS says Cascade River Road areas, including Cascade Pass, need in-person pickup.
Carry an ice axe if snow lingers on the arm (NPS).
Expect a full lot from mid-July through early October (NPS).
Pack a waste bag in case the toilet is buried by snow (The Mandagies).
No dogs. Pets aren’t allowed on this trail.

Camping

A park backcountry permit is required for every overnight stay, and permits are limited. Reservations are made on Recreation.gov, and about 40% of sites are held for walk-up permits issued the day of or day before your trip. Camping is allowed only at designated camps; there’s no camping at Cascade Pass. Fires aren’t allowed at any backcountry camp in the area. The Mandagies say Sahale Glacier Camp has a composting toilet that can be buried in snow early in the season, in which case you pack out your waste. They recommend storing food and toiletries away from tents.

Inside Intel: The Mandagies, who camped there in July 2020, say to “choose any empty campsites you like,” and note that the stone walls are “somewhat protected from the wind.” No camper accounts recommending one specific site were found.
