The park is home to more than 30 mammal species. Some of these, however, such as the American mink (Mustela vison) and the short-tailed shrew (Blarina brevicauda) are not frequently observed. Hiking the Appalachian Trail up Loudoun Heights, gray and fox squirrels (Sciurus carolinensis and S. niger) can be viewed scurrying to stash their food, while eastern chipmunks (Tamias striatus) are commonly seen running right along the trail's edge. In a 2001 mammal survey, the southern flying squirrel (Glaucomys volans) was found to be making its home within the park.
