At 150 ft, it stands above roughly 83% of the 775 documented falls in this guide.

Its water comes from Agawamuck Creek. You'll find it in Columbia, New York. It is protected within Columbia Land Conservancy.

This is a short hike waterfall: reached by a short trail, generally under about a mile each way. A short walk gets you to the viewpoint, so it works for most casual visitors and families. The walk to the main viewpoint runs about 1 miles round trip. Base a visit out of Philmont, the closest town.

When to go: spring. Like most waterfalls, High Falls (Philmont) 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.
