From Cascade Pass, you can also head east and downward towards campsites at Pelton Basin and a popular side-trip to Horseshoe Basin—a spectacular steep walled cirque with waterfalls, wildflowers, and an historic mining site.

Past Horseshoe Basin, the trail continues into the Stehekin Valley, following the course of this scenic river for much of the hike. This trail provides access to the east side of the park, including the village of Stehekin. Because of severe flood damage to the old Stehekin Valley Road, it is now a 23-mile (37 km) hike from the Cascade Pass parking lot to the Stehekin shuttle bus at High Bridge.
