Undine Falls is a waterfall in Park County, Wyoming. It drops roughly 59 feet. Access details and conditions have not yet been verified in person by Fallspots — the data on this page comes from OpenStreetMap and USGS GNIS.

Undine Falls sits in Park County, Wyoming. The falls are inside Yellowstone National Park, a US National Park. The base sits at roughly 6,567 feet of elevation. Drive time is about 5 minutes from Mammoth. OpenStreetMap shows a trail within 20 meters of the marked location, though the name isn't recorded. It draws modest visitor attention — busier weekends, quiet weekdays. Source records come from OpenStreetMap and USGS GNIS.

Dogs are not allowed on the access trail or at the falls. The approach is short and gentle enough for young kids.

Is the water flowing right now?

Most waterfall sites don't tell you this. The waterfall itself is almost never gauged, but a USGS streamgage in the same watershed can tell you whether snowmelt has started, peaked, or run dry.
