The Mount Si trail starts just off the parking lot, near the picnic area and the outhouse.
The trail is moderate for the first two miles, then dramatically evolves into climbing steep switchbacks. The scenery is diverse and eventually flatness out to wind through old growth trees that are wildly impressive. You will be blown away at the massive girth and size of these trees that frame the trail in all directions.
Beyond the old growth forest, the trail steepens further through much younger forest. At three and a half miles a brief break in the canopy yields the first view of the valley to the South. On a clear day Mount Rainer takes over the horizon to the SE for some magnificent views.
At the peak , the trail seemingly ends and the “Lunch Spot”. However the rocky surface known as Haystack can be scrambled with a bit of climbing experience. Caution should be practiced here. Boulders have been known to tumble and critically injure unsuspecting hikers below. If you are up for it, and the conditions permit, the 360 views atop haystack are well worth the extra effort.
