At 209 ft, Hemmed-In Hollow Falls is one of the taller waterfalls in Arkansas — a plunge waterfall worth seeking out.

You'll find it in Newton, Arkansas. It is protected within Buffalo National River (NPS).

This is a backcountry waterfall: a remote, long, or permit-required trek for prepared visitors. The walk to the main viewpoint runs about 5 miles round trip. Base a visit out of Ponca, the closest town.

When to go: Late winter to spring after rain (Dec-Apr). Like most waterfalls, Hemmed-In Hollow 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.
