The park, which covers an area over 3 square miles (8 km2), is managed by Denbighshire Countryside Service which is responsible for the heather moorland, dry stone walls and access paths, and provides information and facilities for visitors. The area is home to wildlife such as red grouse, European stonechat and Eurasian curlew. The summit of Moel Famau lies just within the Flintshire border.
