In the far eastern part of the county is the Floyds Fork watershed, characterized by its many creeks and touting the oldest exposed bedrock in the county: Waynesville Limestone, as much as 500 million years old. Moving from west to east in this region, the landscape drops from 700-foot elevations to 440 feet in the Floyds Fork Creek bed. Floyds Fork Creek is replenished by its many tributaries, including Back Run, Broad Run, Cane Run, Chenoweth Run, Long Run, Pope Lick, and Brush Run. Plentiful regional surface water combined with the sharp drop-offs formed when erosion-resistant limestone caps other easily erodible layers has produced beautiful waterfalls, one of which is in Fairmont Falls Park.
The Floyds Fork section of the Louisville Loop navigates through Beckley Creek Park of The Parklands of Floyds Fork. Construction and maintenance of this section of the Loop has been made possible by a partnership with 21st Century Parks.
The first 2 miles of the Floyds Fork section is currently open (Additional trail miles are expected to be complete in the Fall of 2013). The open portion extends from the William F. Miles Trailhead, along Beckley Creek Park to the Egg Lawn and ends at Thornton Bridge.
