Lancs Live reports. The site had already been closed in May due to a high volume of visitors and the risk to public health amid the coronavirus outbreak.In a post to social media they said: "We are experiencing extremely high levels of vandalism to our temporary barriers and fencing at Fairy Glen."The barriers have been put in place to keep members of the public safe and to prevent people from straying from the short stretch of Public Footpath which cuts across the site."Each day we are finding our barriers smashed, bent and often thrown into the brook and this is putting our staff and other members of the public in danger."We ask that members of the public do not squeeze through, climb over, remove or vandalise the barriers which we have.
