Exit 34 Twin Falls Trail Head: The trail is currently closed at .75 miles...
Twin Falls trail in Olallie State Park is accessible year-round and perfect for those looking for a quick hike near Seattle with a satisfying finish that features two waterfalls. Come one, come all – this trail is fun for the whole family.
From the parking lot, follow the South Fork of the Snoqualmie River for 0.7 miles until the trail begins to switchback up to a viewpoint of the waterfall. Enjoy the giant benches and continue on at your own pace. The trail does get steep in a few sections, but soon you'll hit a set of stairs that lead down to an overlook of the 150' tall Lower Falls. Don't miss this one, it's the most impressive of the bunch.
Back on the trail, climb another half-mile to a wooden walkway and bridge that takes you over a narrow gorge and right on top of a stair-step waterfall. Head to the far end of the bridge and up a set of steps for another variation of the view.
This is the turn-around point if Twin Falls was your destination. The trail continues on for 1.6 miles to the Upper Falls Trailhead (an alternate route to the Falls), along the way intersecting with the Iron Horse Trail.
