Mystic Falls drops 70 ft (21 m) as a cascade waterfall in Wyoming.
The falls are fed by Little Firehole River. You'll find it in Teton, Wyoming. It is protected within Yellowstone National Park (NPS).
This is a moderate hike waterfall: a longer day hike, roughly one to several miles each way. The walk to the main viewpoint runs about 2.4 miles round trip. Base a visit out of Old Faithful, the closest town.
When to go: Summer (June-September). Like most waterfalls, Mystic 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.
