The Brecon Beacons National Park was the first area in Wales to be awarded International Dark Sky status. Stretching from the English border to the wilds of Carmarthenshire and from the South Wales Valleys to the wilderness of Mid Wales, the beautiful and varied landscape has many opportunities to witness some of the darkest skies in the UK.

On a clear night, you can experiences the majesty of the Milky Way as it arches over the night sky and also see up to 3,000 – that’s 2,800 more than most areas of the UK!

Over the past three years of being awarded this prestigious designation, the Brecon Beacons have been working hard with businesses, local residents and visitors to reduce light pollution and make the skies even more special than before. With the reserve being so accessible, offering a fantastic range of landscapes, a rich cultural heritage and an amazing array of wildlife, the Brecon Beacons is a perfect place to escape from the day to day bustle of the world and experience true peace and tranquillity.
