Twin Falls in Snoqualmie National Forest is one of the most accessible and impressive waterfall hikes in the Pacific Northwest, combining old-growth forest, a dramatic river gorge, and two powerful waterfalls into a 2.6-mile round trip. The trail's short distance and dramatic scenery make it one of the consistently recommended introductory hikes near Seattle.
The South Fork Snoqualmie River thunders through the gorge in spring and early summer, and the falls are audible from well before they come into view. A suspension bridge over the gorge provides a memorable aerial view of the lower falls.
The Route
The trail begins at the North Bend trailhead and descends into the South Fork Snoqualmie River gorge through old-growth Douglas-fir forest. The lower falls viewpoint is reached at approximately 0.8 miles via a viewpoint platform. The suspension bridge crosses above the gorge with direct views of the lower falls. The upper falls are visible from a viewpoint at the end of the trail.
Return on the same trail. The suspension bridge provides the trail's most dramatic single experience.
What to Expect
The old-growth forest is the trail's quiet highlight alongside the waterfalls. Some of the Douglas-fir in this gorge are several hundred years old, with diameters that dwarf younger forest trees. The trail is well-maintained and good for hikers of most abilities.
Spring is the most dramatic season for the falls. Winter visits are possible during dry weather but the trail can be icy on the descent sections. The parking area fills on weekends; arrive before 9 AM for reliable parking.
Nearby
North Bend, Washington, is a few miles west on I-90 with full services. The Little Si trail nearby provides a shorter alternative to the main Mount Si climb. Rattlesnake Ledge, one of the most popular hikes in Washington, is accessible a few miles east of North Bend for those wanting a ridgeline view.
Leave No Trace
This trail receives enough use that following Leave No Trace principles is important for preserving the experience for future visitors. Stay on the marked trail to prevent erosion. Pack out all waste. Avoid camping within 200 feet of water sources or the trail. Use existing fire rings only where campfires are permitted, and check current fire restrictions at checking conditions before you go before any visit. The trail and surrounding terrain remain in good condition because previous visitors have respected these norms.
