The original entrance to the park, located on the outskirts of Goreville, was found to be a potentially hazardous driving route, and was replaced by a new entrance located on Illinois Route 37 in the early 1980s.

Although traffic upon it has been practically non-existent since 1982, Ferne Clyffe is also accessible to US Bicycle Route 76 by way of a spur trail along the east side of IL 37.

Ferne Clyffe's acreage holds a number of notable geographic features, including limestone bluffs, naturally forested woodlands, cliff caves, and several small seasonal waterfalls fed by runoff from the upper bluffs in the area.

In the late 1950s, the IDNR constructed an earthen dam across Buck Branch Creek.
