Mount Si
Snoqualmie Region
As of March 25th, 2026, Mount Si is mostly clear of snow, with only light dusting reported near the top. Recent reports from March 23rd note the trail is in great shape after storm damage cleanup, with a few small trees to duck under. Muddy patches are present but manageable.
Earlier reports in March, like March 14th and March 1st, indicated significant snow. Reports from late February (Feb 27th, 22nd, 19th, 16th) consistently mentioned snow and ice, recommending microspikes or snow cleats, especially in the upper sections.
The parking lot continues to have numerous potholes, as noted in multiple reports. Loose rocks near the talus slope at the top were also a concern on March 21st.

Snow on the ground about 2 miles in. Spikes were helpful towards the top. Bring extra layers as it gets colder and more windy towards the top.
Basically the whole trail is covered with snow, a bit icy in the first half and then it gets powdery and more grippy towards the top. I made it up to a smaller peak near the end about a quarter mile a...
We arrived at the trail head around 10am. Plenty of parking. Very large ruts in the parking lot. The trail was covered in snow/ice for about the last quarter mile to the top. While we managed in our t...
