It’s something of an exaggeration to call the Cave Ridge Trail to the top of Guye Peak a “trail,” as it is more of a series of scrambles over boulders and fallen trees connected by short, boot-pounded paths though narrow bands of vegetation. Short and rough, the route aggressively attacks the elevation, conveying you up the slope with only an occasional begrudging switchback or two. At just over mile, things begin to level out and the trail passes by a seasonal pond before beginning the final push to the top.

Be aware that decades of use have resulted in many lesser-used side trails that can be confusing. While there is one sign directing you either to Snoqualmie Mountain or Guye Peak, the trail is unsigned. Dramatic overhangs and big drop-offs make this a popular hike with both hikers and mountaineers year-round. The short trail distance and close proximity to I-90 mean easy access, but can also lend an illusion of relative safety. Use caution near the top, as slick conditions can easily lead to a tumble or worse – quite a number of people have died on Guye Peak since the 1960’s.

Short and brutal, Guye Peak pays dividends in spectacular views. Survey the ski slopes of Alpental and Snoqualmie Pass as well as the whole of Commonwealth Basin. To the west lies Denny Mountain, supporting the slopes of Alpental and beginning a north running ridgeline that includes the Tooth, Bryant Peak and Chair Peak. Snoqualmie Mountain dominates the view to the north, while the Red Mountain steals the show as you swing east to take in Kendall Peak.


Tentatively named Slate Mountain for a time, Guye Peak was eventually named for F.M. Guye, who staked out a number of mining claims on both Guye Peak and Snoqualmie Mountain. Many of the rough paths the crisscross the mountains above Alpental have their origins in the mining activities of the late 1800s.
