Clay Hill Memorial Forest was once part of Clay Hill Farm, which played a significant role in the early 1800s, expanding from 300 to over 4,000 acres, largely due to the labor of enslaved individuals. During the Civil War, it served as a refuge for John Hunt Morgan. You can explore a reconstructed model of an old slave cabin on-site.

There are 4 hiking trails covering nearly 6 miles, ranging in difficulty from easy to challenging. These trails are color-coded and well-marked, featuring informative signs along the way. It is approximately 8 miles from Campbellsville.

One of the trails is the Little Angel Spring, measuring 1.4 miles and marked by green signs. It takes you through a mature beech-maple woodland, showcasing some of the largest trees at Clay Hill. To reach the spring, you'll descend about 100 feet along a trail with steps and a handrail. At the spring, you'll find a small observation deck, a marble angel statue, and a plaque honoring Joan White Howell. This spring is home to a unique group of insects found nowhere else in Kentucky and boasts some of the highest quality water in the Upper Green River.
