Mardis Mill Falls (also called Graves Creek Falls) is a wide block waterfall about 15 feet high and roughly 35 feet across on Graves Creek near Blountsville, in the Locust Fork of the Black Warrior River watershed. It sits beside a historic mill site and is reached from a roadside pull-off with minimal walking.
Its 15 ft drop is taller than about 7% of the 775 waterfalls we track.
The falls are fed by Graves Creek. It lies in Blount, Alabama. The site is on public land managed by Blount County (roadside public access).
This is a roadside waterfall: visible from a road, parking area, or a walk of a few hundred feet. Little to no walking is required, so it suits a quick roadside pull-off rather than a dedicated hike. The nearest town is Blountsville.
When to go: Winter/spring high flow (Dec-Apr). Water volume swings with the seasons here, strongest after snowmelt or rain and lowest in late summer, so check recent streamflow before you go.
