Mount Si Trail

The trailhead for Mount Si is located about 30 miles east of Seattle, near North Bend, Washington. Due to its immense popularity, especially on weekends, the parking lot at the trailhead can fill up very early. Arriving before 7 AM is often recommended to secure a spot.

Yes, a Discover Pass is required for parking at the Mount Si Trailhead, as it is located within the Mount Si Natural Resources Conservation Area. You can purchase a day pass or an annual pass online or at various vendors.

Yes, dogs are generally allowed on the trail, but they must be kept on a leash at all times. Please remember to pack out all pet waste to help keep the trail clean for everyone.

The trail is accessible year-round, but the best time to hike is typically from late spring through early fall (May to October) when the weather is milder and views are clearer. Winter hikes are possible but require appropriate gear for snow and ice, especially at higher elevations.

The trail starts with a gradual ascent through a lush forest with switchbacks. As you gain elevation, the path becomes steeper and more rocky. The last mile is particularly challenging, featuring large rocks and a consistent incline. There's a brief flatter section called 'Snag Flat' with old-growth trees before the final steep push.

As you ascend, you'll find several spots offering panoramic views. A notable viewpoint around the 2.5-mile mark provides stunning vistas of the Snoqualmie Valley. Higher up, the tree canopy breaks, revealing expansive views to the south. The primary destination for many is the Mount Si Viewpoint, just below the summit block known as 'The Haystack'.

'The Haystack' is the true summit of Mount Si, requiring an exposed Class 3 rock scramble to reach. It's located just above the main viewpoint. This final scramble is optional, and many hikers choose to enjoy the views from the base of Haystack Scramble without attempting the climb.

Mount Si Trail is rated as difficult due to its significant elevation gain and consistent steepness. While popular, it is not recommended for beginners or very young children unless they are experienced hikers with a good level of fitness. It's often used as a training ground for more strenuous mountain ascents.

Yes, the route also passes through sections of the Mount Si Old Trail, Old Si Trail, Talus Loop Trail, Snagg Flats Interpretive Boardwalk, Roaring Creek Trail, Creek Side Loop Trail, Douglas Fir Trail, and the Si–Teneriffe Connector Trail.

Wear sturdy hiking boots with good ankle support, and dress in layers as weather conditions can change quickly. Bring plenty of water (there's no potable water on the trail), snacks, a map or GPS, a first-aid kit, and sun protection. Trekking poles can be very helpful for the steep ascent and descent.

The town of North Bend is a short drive from the trailhead and offers various amenities, including cafes, restaurants, and grocery stores, perfect for a post-hike meal or to grab any last-minute supplies.
