Mount Si - Old Trail
Snoqualmie Region
As of late July 2026, Mount Si's Old Trail is in good condition with no significant obstacles reported. The trail is steep and less defined than the newer route, offering solitude as noted in a June 25 report. Hikers should expect full tree cover until the summit, providing shade.
Parking at the Little Si lot was about 3/4 full on a Saturday morning, according to a July 25 report. While the trail is generally clear, one report from July 25 mentions needing to ask for directions around a rocky "lunch spot" to continue to the Haystack. The summit and the final Haystack scramble may be challenging and require caution, as observed by a group in helmets on July 25. Snow is not currently a concern; however, prepare for cooler temperatures at the top, as advised from a May 15 report.
