Hike the Twin Falls Trail along the South Fork of the Snoqualmie River. In 0.5 mile, the trail leaves the river and begins to climb.

At ~1.5 mile reach the bridge that crosses the middle of the "stair step" upper falls and a short distance beyond the bridge, the overlook for the upper falls.

Hall Point

Hike past the falls and up to the John Wayne Pioneer Trail. Travel east on the Palouse to Cascades State Park Trail (formerly John Wayne Trail) to the start of the Change Creek Trail.
