Mt Si/Old Trail
Little Si Trailhead
The Mt. Si Old Trail is far less crowded than the standard route up Mt. Si. We will begin at the Little Si Trailhead, hike part of the Boulder Loop Trail, and continue to the Mt. Si summit on the Old Mt. Si trail. Bring traction devices such as Yaktrax or Microspikes as there will be snow and ice on the upper part of the trail.
