Ground
The club initially played at the Royal Oak ground behind the eponymous public house, before moving to Mousel Barn in 1932. When the club started playing again after World War II they discovered that the ground had been sold off. Two years later they bought three fields on the Causeway, where the Causeway Ground was subsequently built. A stand was erected using a converted tool shed, and two new stands were built in 1949. Floodlights were installed in 1991 and officially inaugurated with a friendly match against Birmingham City. During the 1993–94 season the 18-foot slope from corner to corner was rectified, with the club playing at Worrall Hill while the work was carried out, around five miles from Cinderford. The levelling of the pitch meant banking was created behind one goal and along the side of the pitch opposite the main stand. The ground currently has a capacity of 3,500, of which 250 is seated and 1,000 covered.
