Collene, We made a first visit to F of D last June and stayed at Christchurch (forrestry Com'n site) There are 3 sites nearby including one where you pitch in the forest itself which looked a bit damp to us. The Christchurch site is quite large with for most part sloping pitches. Very popular for tents especially weekends. Facilities could be improved but for the fees charged I would't complain. Small shop on the site.
Symonds Yat is just down the road and you can access the forest at various points around the site which was great for our springer dog. Good for cyclists and walking with a pub up the road and near to Coleford or Monmouth for shopping and a few restaurants. All in all a nice 4 night stay and I did not see another site that I would have prefered to have been at including the sister site just down the road where facilities looked a bit better but seemed very spread out.
