Mount Si - Old Trail
Snoqualmie Region
updated 2 weeks ago
The Old Trail on Mount Si is in good condition, with reports from September 11 and September 8 indicating no significant obstacles. The road is suitable for all vehicles according to reports from September 11, September 8, and August 24. While earlier reports in July noted no bugs, a report from September 11 mentioned yellow jackets as an annoyance, and another from June 25 also noted bugs were not too bad. Bear sightings have been reported, with one on August 24 and another mentioned anecdotally on September 11. Fall colors are beginning to appear near the summit, as noted on September 8 and September 11. The final push to the summit involves navigating the "haystack," which can be intimidating and requires comfort with heights and exposure, as noted in reports from July 25 and June 25.
