The River Tawe (Afon Tawe in Welsh) is a river in South Wales. It flows in a principally south-westerly direction for some 48 km (30 mi) from its source below Moel Feity in the Old Red Sandstone hills of the western Brecon Beacons to the Bristol Channel at Swansea. A fantastic river, among the best anywhere in the UK. The river starts right up on the hillside with a series of three drops beside the road which take you off on a blast downhill, with a long succession of slides and falls through open moorland. The river is picking up water all the way as you go. In high water you practically fly down this stretch! The banks close in and trees appear on the banks as you approach a small weir with a metre high slot to drop over. Soon you reach a tricky rapid where the river squeezes through a narrow gorge with a rock (or boils in high water) in mid-current to slalom around. Shortly after the river bends sharp right without much warning and thunders straight over a big waterfall (Grade 5). This is a fantastic river that changes quite dramatically if the water rises, highly recommended and great fun!!
