Mount Catherine

Mount Catherine is a moderate snow scramble of 8 miles with 2,700 feet of elevation gain in the Snoqualmie Pass area.

getting there

Take the Exit 54 (Gold Creek/Hyak) off of I-90. Park at the Hyak ski Area (2,630 ft).

approach & ascent

Head west up hill along the powerlines and/or along the cabins until about 2,900 ft then head on a 230 degree bearing to Nordic Pass. Follow the ridge to the summit of Mount Catherine.

alternate route

When ski area is closed, hike under the ski chair lifts to the summit of Mount Hyak and then drop down toward the Radio Facility , bearing 300 degrees, on the road. From the road intersection (~3,250 ft) follow the road around until crossing Mill Creek or stay in the timber. After crossing Mill Creek, follow a bearing of 242 degrees to Nordic Pass (~ 1 mi) then follow the ridge to the summit of Mount Catherine. Alternatively, ~0.5 mi from Nordic Pass, head south gaining a broad ridge on the north side to the crest and then turn right and follow the ridge to the summit. This route is ~3,000 feet of elevation gain.


  • It is best to do when snow is present.
  • Be careful to avoid the private land north of the chair lift.
  • Avoid all active ski runs when operating (or walk on the sides of the runs if you have to).
