The National Park Authority, together with all its partners but particularly Brecon Beacons Tourism, continues to help raise the profile of the National Park as a viable tourist destination - not only here but across the world. Our growing reputation is testament to the partnership work we undertake to deliver some of the best sustainable tourism initiatives throughout Europe.
The meeting is designed to focus on how local tourism businesses can develop new ways of working in a way that respects the environment and retains the character of the Beacons.
