Harmony Falls is a waterfall in Washington. Height has not been officially recorded. Access details and conditions have not yet been verified in person by Fallspots — the data on this page comes from OpenStreetMap and USGS GNIS.
Harmony Falls is in Washington. The base sits at roughly 3,510 feet of elevation. Drive time is about 26 minutes from Cougar. A trail — Harmony Trail — runs within 10 meters of the marked location. No public parking is recorded within 2 km, so a longer approach is likely. It draws modest visitor attention — busier weekends, quiet weekdays. Source records come from OpenStreetMap.
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.
