Mount Si
Snoqualmie Region
As of May 9, 2026, Mount Si's trail is largely clear of snow and obstacles, though some slush was reported on April 18. The parking lot remains a significant issue, with numerous deep potholes noted in reports from April 20, April 26, April 27, April 28, and May 3; use caution. The "Haystack" summit scramble is considered difficult and not for novices, especially in wet conditions, as warned on April 28. Crowds are a common factor, with early morning arrivals recommended by a May 3 report. A car break-in was reported on April 18.
