Cathedral State Park, located in Preston County, is home to the largest documented stand of virgin timber remaining in West Virginia. Although the park is relatively small (only 133 acres), the trees there reach as much as 90 feet tall and 16 feet in circumference. Some of the trees in Cathedral are over 400 years old, and the area has been designated as a National Natural Landmark.
The land that would become Cathedral State Park was sold to the state in 1942 by Branson Haas, caretaker of the Brookside Resort. The Brookside had been built in the 1880s to capitalize on the peaceful natural area, and had acquired the Cathedral tract in the 1920s. Hass was adamant that the land be conserved, and the state has left it relatively unaltered. While no longer threatened by timbering, the predominantly hemlock forest could be harmed by the wooly hemlock adelgid, an introduced pest that damages hemlock trees.
Cathedral has a picnic area and several short walking trails that take visitors into the hemlock forest. It had an economic significance of $273,866 in 2015.
