At about 148 feet, Diamond Falls is one of the tallest waterfalls in Arkansas, located in the Ponca Wilderness of the Buffalo National River near Hemmed-In Hollow. There is no maintained trail and reaching it requires a difficult off-trail bushwhack.
At 148 ft, it stands above roughly 82% of the 775 documented falls in this guide.
Diamond Falls sits on Buffalo National River tributary. You'll find it in Newton County, Arkansas. It is protected within Buffalo National River (National Park Service).
This is a backcountry waterfall: a remote, long, or permit-required trek for prepared visitors. Getting there takes a genuine backcountry effort, so come prepared with navigation, water, and enough daylight. Base a visit out of Ponca, the closest town.
When to go: Spring (after rain). Expect the strongest flow in spring and after big storms, with a quieter trickle by late summer; confirm current conditions with the land manager before committing to the drive.
