Mount Si - Old Trail
Snoqualmie Region
As of March 16, 2026, the Old Trail on Mount Si is experiencing significant snow and ice, particularly in the upper sections. Reports from March 16th and March 15th indicate slushy snow turning to deep, packed snow (6 inches to over 3 feet) starting around the Boulder Loop intersection and continuing to the summit. Microspikes are highly recommended, though some found them less effective when snow balled up.
Expect water and mud at the lower elevations, especially on March 16th. Several trees are down across the trail, with the largest noted just before the old road section. Postholing is a risk if deviating from established boot paths. The summit overlook can be windy and cold. Parking at the trailhead is typically straightforward with some potholes. Reports from February suggest less snow, but conditions can change rapidly.

It's been awhile since the last trip report, likely due to the atmospheric river that's been going through North Bend. The trail was in pretty good condition given the weather over the last couple of...
