Up, up, up!
Four miles each way, Mt. Si is a popular hike with nearby rock climbing. On a clear day, hikers are rewarded at the top with a view of the Snoqualmie Valley, Mt. Rainier, and the Cascades.
Members of the Snoqualmie Tribe have historically lived at the base of Mt. Si, and in one creation story, they used a cedar rope to swing between Mt. Si and Rattlesnake Mountain. Named after Josiah Merrit ("Uncle Si,") a settler who built a cabin at the base of the peak in 1862, Mt. Si is now protected as part of the Mt. Si Natural Resource Conservation Area, managed as a native ecosystem for low impact recreation and wildlife habitat by the Washington State Department of Natural Resources.
The Washington State Department of Natural Resources and Mountains to Sound Greenway Trust have rebuilt the entire trail to withstand the over 80,000 hikers that use it each year. Greenway volunteers and conservation corps crews have given over 13,000 hours to trail building, resurfacing and maintenance.
