CHS Alumni Hike - Mount Si Old Trail

Alumni-only hikes offered for graduates of Seattle CHS. Mount Si via the Old Trail led at a CHS 2 pace (2.0-3.0 mph). Here's a better way to hike Mt Si! Explore the quieter trails and classic Pacific Northwest forests of Mt Si. It's a steep trudge up old Mt Si trail, and then a more gradual descent down the Mt. Teneriffe, Talus Loop and Douglas Fir trails to return to the Little Si Trailhead.
