Finishing our wander in Guildford we took a short drive to Chilworth and the old ruined Gunpowder Mills. This has long been abandoned but perfectly safe to wander around. It is about ten minutes walk from the road. It is looked after by Guildford Borough Council and a Public Footpath is access. The construction leads to lovely Urbex photography with the very high walls to the chambers. I don't think we saw another person in the time we were there. Yoo Yoo was in her element, so just enjoy.
