Seymour Peak is located in Mount Rainier National Park, 11 miles east of Mount Rainier (as the crow flies). It is situated immediately southwest of Dewey Lake and west of Dewey Peak. Seymour Peak is the name on maps that is affixed to the dome structure which is north of the true summit. Seymour Peak is ever so slightly on the west side of the spine of the Cascade crest.
Seymour Peak is connected to Dewey Peak (to the east) by a high ridge. Approach can be made from Chinook Pass along the Pacific Crest Trail to Dewey Lakes. From the smaller lake follow a climber's path to the Dewey-Seymour saddle. It's class 3 scrambling from the saddle to the summit. Allow 4-5 hours round trip.
From the summit a nice panoramic view unfolds in all directions. To the west Mount Rainier dominates everything, along with all the peaks on the east side of the park from the Tatoosh Range to the Sourdough Range. To the south, Mount Adams and the Goat Rocks.
Seymour Peak can be seen from the Highway 410 switchbacks on the west side of Chinook Pass. It can also be seen from Highway 123 just south of Cayuse Pass. However, the roads over Chinook and Cayuse Passes are closed during winter due to snowpack, check road condition status before attempting.
Seymour Peak is named for William Wolcott Seymour: banker, mayor of Tacoma, and contributor to the scouting movement. Seymour served as president of the Tacoma Park Board from 1909 to 1911 and as Mayor of the City from 1911 to 1914.
