Approach to Bismarck
End of Bismarck Trail
Views from approach to Bismarck
Along Pear Butte Trail
Bismarck Peak is the high peak which anchors the southern terminus of Nelson Ridge, the high north-south trending ridge southeast of Bumping Lake. Along with Mount Aix, these two peaks constitute the highest peaks between Mt. Rainier and Yakima. This area is dry as it lies east of the Cascade Crest. Consequently, this area melts out earlier and offers good early season access while the Western slopes of the Cascades are still snowbound. Furthermore, your chances of finding good weather here are much better than west of the crest. In mid-summer, many may find this area to be a bit too hot. Consequently, one might want to save this trip for a cool or cloudy day.

The majority of the trip to Bismarck lies along good trail. Even though the Green Trail maps show a trail to the summit, this is incorrect. The final 1200 feet will be a steep scree scramble to an airy summit. The views of Mt. Rainier to the Northeast, the Goat Rocks Wilderness to the Southwest, and Mount Aix to the North are outstanding.

Getting There

Summit of Bismarck Peak
Summit Scramble of Bismarck
Summit Ridge
Drive SR-410 East over Chinook Pass, going 19 miles and turning right onto the Bumping Lake Road. Go 11 miles to a junction, and take the left fork, Road #20080, 1.5 miles and just before a bridge over Copper Creek, turn left up a steep road signed "Mount Aix Trail." Go just beyond the steep side road to the Mount Aix Trail and find the trailhead to the Pear Butte Trail #979. Elevation: 3700 feet.

Travel 4.7 miles along Trail #979, then turn left (east) at the Bismarck Peak Trail #983. The Trail is about 3.5 miles to the base of the summit at 6400 feet. Leave the trail and scramble up loose rock and dirt (Class 2) up the Southwest Ridge of Bismarck. This is a long day. Fifteen miles round-trip, and about 4000 feet elevation gain with lots of ups and downs.
