We took the bootpath starting at the first Alpental parking lot (just south of the Snow Lake trailhead). The first section of the trail was steep, rocky, wet (the trail is a creek for a while), and a bit brushy. When the trail got to a clearing it forked left to Snoqualmie Mountain and right to Guye Peak. We took the right fork to the top of the ridge and another intersection, we took the right fork along the ridge to Guye Peak (the left fork must lead to Commonwealth Basin). There was a bit of easy rock scrambling in the last part of the trail.
