Seattle Trails

Seattle, WA: Mount Catherine

Cruise huckleberry meadows and tackle steep, switchbacking turns on this 2.8-mile out-and-back to Mt. Catherine's summit and a survey-worthy perch above Keechelus Lake and Snoqualmie Pass.

A popular trail for snowshoers and skiers, this 1.4-mile uphill in the Snoqualmie National Forest (ck: 425-888-1421) doesn’t draw tons of hikers—which makes the views from the 5,052-foot summit that much sweeter. The trail begins by following an old logging spur on the north side of Forest Road 9070. Within 300 yards, it turns rockier as it begins switchbacking steeply uphill. Near the trail’s half-way point, you’ll have climbed more than half the 1,200-foot elevation gain and forested switchbacks give way to a steady ridgeline climb with peek-a-boo views of surrounding peaks. The trail’s mischievous efficiency means you’ll encounter several false-summits, but the actual pinnacle hosts rusted cables and bolts—relics of 1920s aviation navigation aids. Though the trail is mostly rough and rocky, it’s easy to follow and there’s a short scramble toward the rocky peak itself

On a clear day, from the top you’ll look down on Keechelus Lake with I-90 hugging its shore. To the south, Rainer quietly lurks behind Silver and Tinkham Peaks. Humpback Mountain is immediately to the west and Red Mountain stands boldly to the north.
