Summiting Mount Si: Your Guide to Cascade’s Panoramic Powerhouse

Mount Si lords over North Bend, Washington, with a rugged silhouette that dares hikers to meet its steep trails head-on. This 4,167-foot peak rewards every footstep with forested trails that press through Douglas fir and western red cedar, branches seeming to guide you upward. As you climb the nearly 8-mile round trip with an elevation gain of 3,150 feet, the terrain challenges with rocky switchbacks and exposed ridges that test endurance and sure footing.

The trail is a steady pulse of effort—steady breathing, beating heart—with nature pushing back, fierce and unapologetic. Streams glimmer-and-hum alongside, daring you to pause, hydrate, and respect the pace. Along the way, moss-draped trees watch silently, the scent of damp earth thick around you.
