Eryri is the fourth largest National Park within the UK family and it is legally required to fulfil two statutory purposes:

  • To conserve and enhance the natural beauty, wildlife and cultural heritage of the area.
  • To promote opportunities for the understanding and enjoyment of the special qualities of the National Park by the public.

We also have a duty to seek to foster the economic and social well-being of local communities within the Park.

The guidance below will offer event organisers practical advice on how to undertake these activities in a safe, responsible, sustainable and efficient manner and which are not detrimental to National Park purposes and to ensure that those special qualities are maintained.
