Tomyhoi Lake

In the Mount. Baker Wilderness, the 4-mile trail to Tomyhoi Lake climbs steadily to Gold Run Pass where you can see both American Border and Canadian Border. It's 2 mi and 1,500 ft of elevation gain to the pass, and another 2 mi but 1,500 ft of elevation loss to the lake.

On The Trail

This trail is within Mount Baker Wilderness. Gold Run Mining Company workers built this trail in the early 1900s.

The trail begins with switchbacks taking you through an avalanche path thick with wildflowers in early summer, then enters timber and climbs until it breaks out to a flat bench in a meadow. The junction with Yellow Aster Butte Trail is about 1.5 miles from the trailhead. Stay to the right at the junction and continue upward through the meadow to Gold Run Pass.

The steep, pyramid shaped, reddish peak north of the pass is Mount Larrabee. American and Canadian Border Peaks are visible to the north. From the pass, the trail quickly loses elevation, and a half mile below the pass reaches a meadow-covered bench known as Coyote Flats.

The trail continues to the lake, which is a popular fishing spot. Camping is available near the lake. Avalanche debris and downed trees make the last half mile of the trail to the lakeshore and camps hard to follow.
