Snoqualmie Region
The Mount Si via Mount Teneriffe Trail is generally in good condition, with recent reports from May 2026 indicating that trail crews have trimmed thorny overgrowth and cleared encroaching evergreens. The trail to the summit of Teneriffe was reported as clear and in good condition on May 24. Some streams are present on the lower sections, but they were not challenging to cross on May 22. Parking availability varies, with the Teneriffe lot being relatively empty early on May 22 and May 19, and about 25% full around 9 am on a holiday weekend. The Teneriffe trail itself is described as steeper and rockier than the Mount Si trail, particularly about 2 miles past Roaring Creek, and hiking poles were recommended. There were no significant snowpack issues reported in May 2026.

I arrived at the Mt Si parking lot shortly before 10 am. I managed to find one parking space, all the way out towards the road. The early birds were starting to leave so parking spaces were already st...
