Mount Larrabee

A scramble near Mount Baker of roughly 10 miles and 4,400 feet of elevation gain.

driving directions

Follow US 542 (Mount Baker Highway) past Glacier. Turn left on Forest Road 3065, which is at the highway maintenance facility. Drive 5 miles to small parking area at the Tomyhoi Lake trailhead. A high clearance vehicle can continue to the Twin Lakes trailhead. The last two miles have some tight switchbacks, rocky sections and deep dips.

approach & ascent

From the Twin Lakes trailhead, hike north to Low Pass, then to High Pass. Continue on trail to about 6,400 ft and then traverse left and down to basin, losing 100-200 feet of elevation. Ascend boulder fields, then scree and dirt to the southwest spur at ~6,900 ft. Find the gully system in rocky face. Of two narrow channels (30 feet apart) take the right one. Ascend the narrow, then open gully to broken rock to attain ridge top. Follow the ridge, favoring the west side, to the summit. Most of ridge top has a way trail and the route is partially marked with cairns after leaving the basin, but the cairns may be far apart and the way trail may disappear for long stretches. If you lose cairns or way trail most gullies probably work though some may be more difficult than others.
