Mount Si - Old Trail
Snoqualmie Region
As of June 25, 2026, the Mount Si Old Trail is largely snow-free and in good condition. A single downed tree was reported on June 25th, and hikers should expect a narrower, steeper, and less defined trail than the new trail. Solitude is a common experience on this route.
Earlier reports from April (April 3rd, 4th, 17th) noted patchy snow and ice, particularly on the upper sections and boulders, with some recommending microspikes. By mid-May, snow was minimal, though slippery conditions at the summit were noted during a brief snow shower. Parking availability can vary; a report from April 4th indicated full lots by 7:45 am for Mailbox Old Trail, suggesting potential crowding for Mount Si.

My first time up the old trail. The trail was snow/ice free up to about 2 miles and then quickly became icy. Typical trail around here. Snow, then melt and then freeze. Spikes essential that last mile...
