 Although the site is owned and managed by the AWT, the old quarry is maintained by cavers and mine explorers who remove graffiti and litter as well as repair damage and naturally occurring falls to keep passages open and relatively safe.Access to both the caves and tower is dangerous and people should not descend the one or ascend the other without expert guidance.Visitors are also reminded that anyone who destroys or damages a bat roost is breaking the law and susceptible to heavy fines or imprisonment.
