Lewis Falls is a smaller block waterfall in Wyoming, with a drop of about 30 ft.

Its water comes from Lewis River. It lies in Teton, Wyoming. The site is on public land managed by Yellowstone National Park (NPS).

This is a roadside waterfall: visible from a road, parking area, or a walk of a few hundred feet. The nearest town is Grant Village.

When to go: Summer (June-September). Like most waterfalls, Lewis 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.
