Narroways (The Mound) will be closed for firework season this year after over 1000 (police estimate) people were up there last Guy Fawkes and left a huge amount of rubbish. We had reports from people that it became quite chaotic later on, with fireworks let off into crowds.
It is a shame for small family gatherings but the nature reserve gets abused by large groups of people, many arriving from some distance away, swelling the numbers. We have a duty of care to reduce the risk (the recent event in Seoul where many young people died in a crush reminds us of what can happen when things go wrong). The combination of a steep sided hill, in darkness, with fireworks and fires and a huge number of mainly young people, many of whom may be drunk or have taken drugs, is too great a risk.
