Princeton Run Nature Preserve

Princeton Run Nature Preserve is located in Mercer County, southern West Virginia, managed by the West Virginia Division of Natural Resources. This 1,031-acre preserve conserves one of the state's finest examples of mature hardwood forest and an intact headwater stream system, Princeton Run, that supports abundant biodiversity. The preserve is largely forested with species including Eastern hemlock, yellow poplar, oak, and hickory. It lies within the Ridge and Valley physiographic province and contains a rugged landscape of narrow ridges and steep hollows. Historically, the forest was spared from widespread logging, making it a rare remnant of old-growth and mature forest habitats valuable for ecological research and conservation. Visitors to Princeton Run Nature Preserve can explore several informal hiking paths that follow the stream valleys, offering opportunities to view native wildlife such as salamanders, songbirds, and black bears. The clear water of Princeton Run supports diverse aquatic life, making the preserve important for freshwater ecosystems as well. Although facilities are limited, the preserve appeals to nature enthusiasts interested in forest ecology, botany, birding, and serene forest hikes away from developed recreation sites. The preserve's protection also contributes to water quality downstream and acts as a forest carbon sink. Its relatively remote location provides quiet solitude with minimal human disturbance.
