CHS 2 Hike

Field trip: Conditioning Hiking Series

CHS 2 Hike - Mount Si Old Trail

NEW DESTINATION: Mt Si Old Trail. Mount Si via the Old Trail led at a CHS 2 pace. 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.

COVID-19: Learn about our most up-to-date guidance for participants and leaders on our COVID-19 Response page. All participants and leaders must agree to the COVID-19 Code of Conduct before participating in this Mountaineers activity.

Please note that a Discovery Pass is required for parking. 

This is a challenging hike that is designed to be a little easier on the knees by taking a steeper route up with a more gradual descent. This loop route maximizes less trafficked trails on Mt. Si.

We plan to stop at Scott's Dairy freeze for a post-hike outdoor meal - burgers and/or ice cream for those interested. We will not be stopping for an extended lunch on the hike, so bring plenty of snacks for the short breaks on the trail.

Leader will provide additional details to registered participants via email.
