Casper’s Not-So-Hidden Secret: Hell’s Half Acre

Believe it or not, this out-of-this-world landscape is located just a few feet from the highway, yet travelers pass by it every day without knowing! A quick 30-mile drive from Casper, Hell’s Half Acre is well over half an acre, encompassing 960 acres of deep ravines, caves, rock formations and hard-packed eroded earth. Native American tribes used the ravines during their hunts, driving thousands of bison over the cliffs.

Fun fact: Hell’s Half Acre was a filming location for the fictional planet of Klendathu in the movie “Starship Troopers” in 1997!

The 960 acres and deep ravines, caves and rock formations of Hell’s Half Acre are located 40 miles west of Casper and just off Highway 20/26. Photo courtesy of Visit Casper
