Wales' spectacular scenic rural heartland, and the site of Brecon Beacons National Park, Powys is a lush land of verdant mountain valleys, craggy caves and quirky towns. The staunchly nationalistic area offers appealing outdoors opportunities. Canter on horseback through the rugged Brecon Beacons mountain range. Walk or cycle the charming valleys. Other draws are commanding Powis Castle near Welshpool and the Centre for Alternative Technology, a sustainable development center, near Machynlleth.
