From the ranger station at the Longs Peak trailhead, From the Ranger Station, start up the great East Longs Peak trail. Hike 0.5 miles to a signed trail junction - stay left on the main trail. Continue up through the forest and pass Goblins Forest. The trail comes close to Alpine Brook a couple of times. Switchback up a hill before crossing Alpine Brook on some log bridges. Leave the heavy forest shortly after the stream crossing and continue up to tree line near 11,000' (approximately 2.5 miles from the trailhead). Longs is now in view as well as Mt. Lady Washington. Turn left at the signed junction with Battle Mountain (
2) and keep hiking west along Mills Moraine to the Chasm Lake trail junction at 11,550'.
Turn right at the Chasm Lake trail junction, continuing up the main trail to the Boulderfield, but after just a quarter mile, turn left off-trail and begin to ascend directly to Mt. Lady Washington's visible summit ridge (
3). Steep Class 2 Alpine tundra (
4) gradually gives way to Class 3 rock (
5) approaching the ridge at 13,150'. Upon attaining the ridge, take in a view of Storm Peak across the Boulderfield (
6). Turn left (west) on the ridge to reach the summit (
7) of Mt. Lady Washington at 13,281', around 4.5 miles from the trailhead. There is a summit register.
Study the ascent route up Storm Peak (
8). It is steep enough to be problematic if wet or icy. Descend Mt. Lady Washington from the saddle between the summit and the sub-peak to the north, traversing slightly during descent to get closer to Storm Peak. Lose 500' of altitude to the Boulderfield at around 12,750'. From the middle of the Boulderfield (
9), the Storm Peak ascent is about three-quarters of a mile of sustained Class 3 rock (
10) (
11), with plenty of Class 4 options.
Reach the summit ridge of Storm Peak at 13,320'. Take in outstanding views of Glacier Gorge (
12) and Longs Peak (
13). The summit is the high point furthest east, and there is a summit register.
Descend Storm Peak to the south (
14), heading toward the Boulderfield and Granite Pass in the distance. Link up with the standard Boulderfield trail and follow it down to the Ranger Station.
