Hex Mountain
Snoqualmie RegionBest Jun–Oct
A quiet ridge hike above the Cle Elum valley with a windswept summit and sweeping Teanaway views.
About This Trail
Hex Mountain rises above Lake Cle Elum in the Salmon La Sac area of the Snoqualmie Region, reaching a 5,034-foot summit after a steady 2,900-foot climb. The route follows an old woods road before joining a forested ridge, then narrows as trees thin and the trail pushes toward a bare, windswept top. Wildflowers fill the upper meadows in early summer.
From the summit, the horizon opens onto the Teanaway peaks, Mount Stuart, and the broad basin of Cle Elum Lake. The ridge is exposed and holds cornices into late spring, so early-season hikers should approach the summit ridge with caution. Winter access via NF-116 is closed, and the lower trail now crosses private land that is inaccessible to vehicles.
Few people visit compared to the popular Teanaway summits nearby. Roadside parking at the trailhead is limited. Park along the shoulder before the trail or use the pullout about 0.6 miles south; the fire station 0.2 miles south does not allow hiker parking.
