Continuing the S-Curve tradition, the Upper Wall has mostly sport routes in the 5.10 - 5.11 range. This wall is smaller and more broken than the lower wall. A few routes require a walk-off to the west, but most can be lowered with a single rope.
Getting There
From the digital sign at the mouth of Big Cottonwood Canyon, drive 4.25 miles up canyon until the very obvious S-Curve in the road. There is a small parking lot and also room to park along the side of the road. Follow the Mill B North Fork trail on the north side of the road to the third switchback as for the Lower Wall. Branch off to the east and follow the length of the Lower Wall to the east. Find a trail that rounds the east end of the Lower Wall and head up a gully to the north to read the Upper Wall.
