Shell Falls is a cascade waterfall in Wyoming with a documented drop of 120 ft (37 m).

Shell Falls sits on Shell Creek. It lies in Big Horn, Wyoming. The site is on public land managed by U.S. Forest Service (Bighorn National Forest).

This is a roadside waterfall: visible from a road, parking area, or a walk of a few hundred feet. The walk to the main viewpoint runs about 0.1 miles round trip. The nearest town is Shell.

When to go: Late spring to summer. Like most waterfalls, Shell Falls runs highest after snowmelt or heavy rain and can thin out in late summer, so it's worth checking recent streamflow and the land manager's conditions page before a long drive.
