The Brecon Beacons National Park was the third of Wales's designated areas to be opened on the 17 April 1957, and the first to be opened in Wales, preceded by the Snowdonia and Pembrokeshire Coast National Parks in 1951 and 1952 respectively.
The Brecon Beacons National Park is located in South Wales, within the United Kingdom and an area, most of which is within the county of Powys though the far west just reaches the county of Carmarthenshire, while the east is just inside Monmouthshire near Abergavenny.There is a National Park Visitor Centre in the hills near Libanus, just south of Brecon, a good place for both walks and to gain further information about the National Park. Brecon and Abergavenny (though just outside the park) are both market towns with a selection of shops, and tourist iinformation centres.
In the south of the park, The Brecon Beacons highets peak, Pen y Fan mountain at 886 metres / 2907 feet is a popular walkers destination and another a great area for walks is in "Waterfall Country" near the village of Ystradfellte and south of this position where you will find numerous falls and purpose made car parks with way marked trails for you to explore, particularly impressive after rain though care is required. Also in the south and alittleto the west, the National Shocaves Centre for Wales at Day-yr-Ogof near Abercraf is a popular desination for wisitors with a dinosaur park, museum and the caves themselves, one of which has a waterfall inside the cave.
