Mount Si - Old Trail

Snoqualmie Region

updated 2 weeks ago

As of late April 2026, the Mount Si Old Trail is largely clear of snow, with reports from April 4th indicating it was dry. However, earlier reports from April 3rd and April 17th noted patchy, crusty snow and ice, especially in the last half-mile and around the boulders near the top, with one report from April 17th mentioning several feet of snow by the Snoqualmie Valley lookout. Microspikes were helpful in these icy sections according to several reports. Several blowdowns were noted in March, but recent reports indicate the trail is in good shape with only minor obstacles. Parking was reportedly full by 8 am on a Saturday in early April.

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...

I hiked via the old trail and cam back via the new trail and made a loop. I recommend micro spikes for last half mile. Otherwise, the trail is dry.
