A pre-Roman open-cast ore mine, overgrown with eerie moss-covered trees, Puzzlewood is a 14-acre woodland web of paths, weird rock formations, tangled vines, rickety bridges, 200 uneven steps and dark passageways seemingly designed to leave you disorientated. Parts of hit TV shows Dr Who and Merlin, as well as Star Wars: The Force Awakens, were shot here. There’s a mile of pathways to explore and kids will love the farm animals. Find it a mile south of Coleford on the B4228.
