The Cenarth Falls is a cascade of waterfalls just upstream of the road bridge in the village of Cenarth in Ceredigion, bordering Carmarthenshire and Pembrokeshire, Wales. It is notable as the first significant barrier on the River Teifi that salmon and migratory sea trout encounter on their return to their home river as they make their way upstream to spawn. Because of this, and the very attractive setting of the falls in a natural wooded valley, the falls have become a significant visitor attraction in Ceredigion, including in the autumn when the fish can be watched leaping up the falls.
