Overview
Excelsior Peak is the workhorse climb of the Mt. Baker area's less-traveled trail network. While the Heather Meadows trails get the majority of visitor attention, Excelsior Peak draws hikers willing to earn their views through a sustained forest climb that culminates at a former fire lookout site with some of the widest vistas in the region. The trail passes through some of the finest old-growth silver fir and mountain hemlock forest in Mt. Baker-Snoqualmie National Forest, making the lower half of the route worth the trip even in marginal weather.
The summit at 5,700 feet was used as a fire detection point for most of the 20th century. The lookout structure is gone, but the site's strategic elevation and position between the Nooksack River valley and the Mt. Baker massif make it a logical place to scan the horizon. On clear days, the San Juan Islands are visible to the west, Mt. Baker fills the south, and Canadian peaks define the northern skyline.
The trailhead is less visited than those closer to Highway 542's terminus, which means you are more likely to have the summit to yourself on weekday mornings. This is a good option if Artist Point trails feel too crowded.
The Route
Miles 0 to 2.0: Canyon Creek Forest
The trail begins near Canyon Creek at roughly 3,000 feet and climbs through a classic old-growth Pacific Northwest forest. Western red cedar, Douglas fir, and old-growth silver fir dominate the first two miles. The canopy is dense and the understory lush, with sword fern and vanilla leaf covering the forest floor. The trail gains about 1,000 feet in this section, largely through moderate switchbacks on a well-maintained tread.
Several seasonal creek crossings occur in this section. They are typically easy to manage by July, though early season crossings may require some route-finding around high water.
Miles 2.0 to 3.5: Subalpine Transition
The forest begins thinning at about 4,000 feet as the trail enters the subalpine zone. Silver fir gives way to smaller mountain hemlock, and the ground cover transitions to heather and huckleberry. Views begin opening to the west, looking down into the Nooksack drainage.
This section includes the steepest climbing on the route, gaining approximately 1,400 feet over 1.5 miles. The grade is sustained but the trail is well-graded and rarely difficult underfoot. Snow can persist in this section into mid-July.
Miles 3.5 to 4.2: Summit Plateau
The trail breaks out of the last trees and crosses an open meadow plateau to the former lookout site. The final 0.7 miles is largely flat to gently rolling, providing a gradual decompression after the steeper lower climb. The summit plateau extends in multiple directions with no single clear endpoint; the lookout footprint is the traditional turnaround point.
Views from the summit include Mt. Baker to the southeast, the Twin Sisters Range to the south, and the Cascade foothills extending west toward Puget Sound. The Nooksack River valley is visible far below, and on clear days the Canadian Cascades line the northern horizon.
When to Visit
July through September covers the reliable season. The lower forest section is walkable in June in most years, but the upper meadow section may hold snow until mid-July. September is a fine choice for this trail, as the views are often clearest in early fall and the huckleberries ripen.
The trailhead itself does not depend on Artist Point road conditions, which gives it an advantage for early season visits. Forest Road 31 is a lower-elevation approach compared to Highway 542's upper terminus and typically opens earlier.
What to Bring
- Many hikers carry 2 to 3 liters of water given the sustained climb and limited water sources above treeline. Individual needs vary.
- Trekking poles are useful on the sustained descent.
- A wind layer: the summit plateau is exposed and wind is common even on warm days.
- Snacks for a full-day outing.
- An offline map. Cell service is absent throughout this area.
- Bug repellent is useful in the lower forest section during June and early July.
Practical Details
A Northwest Forest Pass is required at the Canyon Creek Trailhead (as of 2026). The Interagency Annual Pass covers this fee. Veterans and active military may qualify for a free pass; see veteran benefits for national forests for details.
No restrooms at the trailhead. Wilderness ethics apply throughout. Follow the principles in the Leave No Trace guide for waste management, camp selection, and fire practices.
Dogs are allowed and must be leashed. Group size in wilderness areas is limited to 12 people. Overnight campers should self-issue a free wilderness permit at the trailhead register.
For current conditions including trail snow coverage and forest road status, check the pre-trip conditions resources.
Getting There
From Highway 542, approximately 1 mile east of Glacier, turn north on Forest Road 31 (Nooksack Road). Follow FR 31 for approximately 14 miles to the Canyon Creek Trailhead. The road is gravel for most of its length and high-clearance vehicles are recommended in the final miles.
From Bellingham, the total drive to the trailhead is approximately 70 miles. From Seattle, add 90 miles to that estimate. GPS coordinates for the trailhead: approximately 48.891°N, 121.896°W. Download offline maps before leaving cell coverage in Glacier.
Supplies and gas are available in Glacier on Highway 542. The Mt. Baker Ranger District in Sedro-Woolley can provide current road and trail conditions by phone or through their website.
