The Mount Si Trail is one of the most popular trails in Washington, and for good reason. Less than an hour from Seattle, the summit offers incredible views of the Snoqualmie River Valley and the surrounding area.
There is a very large parking area at the trailhead, but it does fill up on warm weekends. Per usual, it’s best to arrive early. A Discover Pass is required.
The hike is hard enough to be a challenge, but not so difficult that weekend warriors can’t climb it. The trail is almost entirely uphill, with some brief flatter sections to catch your breath. You’re mostly hidden in the lush forest, until roughly 3.5 miles in, when you finally break out of the trees and the views begin.
Once at the top, you have two options. Most hikers take in the views and then return the way they came. For the more adventurous, you can scramble up the Haystack. This rocky outcropping is the true summit of Mount Si, but do not underestimate this final challenge. Many hikers have been injured or stuck here, so if you do not have experience scrambling, it’s best to pass.
As with all trails in the area, this hike is entirely different during winter. If there is snow on the ground, you’ll likely need traction equipment and hiking poles.
