A number of small towns and villages lie within or directly besides Brecon Beacons National Park and can serve well as a base from where to discover the park. For this reason, many have become rather popular tourist destinations with proper facilities for travellers. Good examples include Abergavenny, Brecon, Crickhowell, Llandeilo, Llandovery, Hay-on-Wye (famous for its book stores) and Merthyr Tydfil. Other options are Brynaman, Govilon, the small villages Llangadog, Capel Gwynfe and Bethlehem, Llangorse, Pontneddfechan, Talgarth, Talybont-on-Usk, and the lovely parish of Myddfai.The Brecon Beacons (or simply 'the Beacons') can refer both to the central range of mountains which stretch east from Storey Arms to Talybont and also to the national park as a whole which contains other extensive ranges as outlined below. Though use of the alternative term 'the Brecons' has increased in recent times, it is not used locally and will not win you friends! The mountain area on the east of the national park (extending to the English border) is called the Black Mountains, and the area on the west of the park (towards Llandeilo) is known as the Black Mountain (singular). Old writings suggest that the entire collection of mountain massifs between Abergavenny and Llandeilo was once known as the Black Mountain - which helps to account for some of the confusion that arises with modern naming of the area.
