River Caerfanell At Blaen-y-Glyn Waterfalls, Brecon Beacons, Powys, Wales Stock Photography

Much of the water that fills Talybont Reservoir begins its journey high up in the mountains at the head of the Talybont Valley in the eastern Beacons. At Blaen-y-Glyn, the infant River Caerfanell, the Nant Bwrefwr and other streams tumble down from the hills over tremendous clusters of picturesque waterfalls. There are pleasant walks to these falls from Natural Resources Wales car parks at Upper Blaen-y-Glyn grid reference SO056176 and Lower Blaen-y-Glyn SO064169.
