Wolf Den Run State Park is a public recreation area located on Catoctin Mountain in Frederick County, Maryland. The state park has scenic overlooks of the surrounding area and offers hiking trails for all skill levels. It is managed by the Maryland Department of Natural Resources. The park originated with donations from Thomas Lincoln Casey and Mary Averell Harriman who wanted to preserve an area of land that would be forever wild and open to the people. Their wishes were honored when they donated more than 1,000 acres to the state for creation of the park which opened to the public in 1948.
The name “Wolf Den” came from the Scottish word for den or cave and was chosen because it seemed appropriate for such a secluded spot. The original entrance to the park had been through private property but as time passed this became difficult to obtain. In 1955, after lobbying by local residents, the state government agreed to move the main entrance to the park from its previous location to what is now the park’s visitor center parking lot. This made way for development of Route 40 which runs over the park grounds. To make up for lost revenue, the state implemented a special entrance fee for this park.
The fees, charged per vehicle, start at $10 per day for a single-day or $8 for residents with an MD license plate or DC plates or those holding permits valid in any other state. Fees are waived for honorably discharged veterans and Maryland residents age 62 & older and their spouses. Passes good for three days or a week are also available; annual passes good at all 22 state parks charging fees are offered at a cost of $75 for out-of-state visitors or $60 for Marylanders.
