How to get there

- Watson Lakes Trailhead
The key trailhead for Noisy-Diobsud Wilderness and the starting point for the Anderson/Watson Lakes approach. A valid Recreation Pass is required.
- Anderson/Watson Lakes Trail
The wilderness's only trail-access corridor, reached from Watson Lakes Trailhead rather than a separate road entrance. Near the boundary, the Anderson Lakes Trail leads outside the wilderness; the Watson Lakes Trail continues inside.

Steep forest valleys and alpine lakes
Noisy-Diobsud Wilderness lies in northwestern Washington, just south of Baker Lake and beside the southwest corner of North Cascades National Park. Designated in 1984, it encompasses 14,666 acres managed by the Forest Service. Mount Watson rises to 6,234 feet above deep drainages and abruptly rising ridges. Noisy Creek flows north and Diobsud Creek flows south through lower forests of old-growth fir, cedar and hemlock. Ferns, mosses, salal, elderberry and salmonberry fill the creekside understory, while alpine meadows open along the ridge tops. Black-tailed deer, elk, black bears and northern spotted owls inhabit the forest. The landscape is not an extensive trail network: its single trail-access corridor reaches high lakes, leaving much of the steep, densely vegetated interior beyond maintained hiking access.
Choosing between Anderson and Watson Lakes
The Anderson/Watson Lakes Trail provides the only trail access into Noisy-Diobsud Wilderness. It approaches from the west, with Watson Lakes Trailhead serving as the key starting point. Near the wilderness boundary, the Anderson Lakes Trail leads to a small cluster of lakes outside the protected area. The Watson Lakes Trail continues into the wilderness and ends at Watson Lakes. That boundary distinction matters when choosing a destination: a hike to Anderson Lakes visits the neighboring lake country rather than entering Noisy-Diobsud itself. Both lake groups offer views of surrounding peaks, and the corridor supports day hiking and backpacking. Keep plans focused on these established trails unless equipped for the steep ridges, deep drainages and thick understory that characterize the surrounding terrain.
Wet conditions, summer insects and camping rules
Annual precipitation reaches 150 inches, making rain protection and a way to keep essential gear dry sensible parts of a packing list. Both lake groups are notoriously buggy in summer; insect protection deserves space alongside layers for exposed alpine terrain. Away from the trail, creekside vegetation includes devil's club and a dense, foot-entangling understory, so drainage bottoms should not be treated as easy travel corridors. Give wildlife space and keep food secured, particularly in black bear habitat. Access is hiker only, and wilderness regulations apply. At Watson Lakes, camping is allowed only in designated sites and campfires are prohibited. A valid Recreation Pass is required at Watson Lakes Trailhead. Confirm current access conditions and applicable requirements with the Mt. Baker Ranger District before departure, and follow Leave No Trace practices throughout the trip.

Sample itineraries
- Watson Lakes day hike · 1 day
Start at Watson Lakes Trailhead and follow the Anderson/Watson Lakes Trail. Continue on the Watson Lakes Trail into the wilderness, ending at Watson Lakes before returning. This is the wilderness’s only trail access; expect alpine lake scenery and heavy insect activity in summer.
- Watson Lakes overnight · 2 days
Hike from Watson Lakes Trailhead to Watson Lakes and stay only in a designated campsite. Spend the remaining daylight enjoying the lakes and surrounding peaks, then return the following day. Campfires are prohibited at Watson Lakes; confirm camping arrangements with the Mt. Baker Ranger District before departure.
- Anderson Lakes boundary outing · 1 day
Use the shared Anderson/Watson Lakes approach, then take the Anderson Lakes Trail near the wilderness boundary. Visit the small lake cluster and return along the approach. Anderson Lakes lie outside Noisy-Diobsud Wilderness, making this a nearby alternative rather than a trip into the wilderness itself.
Seasonal conditions
Spring
Spring; confirm current trail and access conditions
Plan conservatively around wet conditions in terrain receiving up to 150 inches of precipitation annually. Steep ridges and deep drainages make off-trail shortcuts a poor choice. Check conditions before committing to the alpine lakes.
Summer
Summer
Both Anderson Lakes and Watson Lakes are notoriously buggy in summer. Carry insect protection and rain layers; the wilderness’s high annual precipitation makes dry-weather assumptions unwise.
Fall
Fall; confirm current trail and access conditions
Prepare for wet weather and changing conditions between lower forest and alpine terrain. Keep the outing within available daylight, and check the forecast rather than assuming the lakes remain suitable for a casual hike.
Winter
Winter; confirm conditions before planning access
Do not assume the summer hiking description applies to winter. Check trailhead access and mountain conditions with the managing agency. High alpine lakes, steep ridges, and substantial precipitation call for conservative decisions and equipment matched to the forecast.
