About The Clywedog

The Clywedog rises in the heart of the Radnor Forest and joins the Ithon at Crossgates. The Passport calls it a discreet stream that was one of the first tributaries to be restored by the Wye and Usk Foundation, and says it offers some fast improving trout fishing. It is a small river with 1¼ miles of fishing available, and it is lightly fished. The Passport suggests a rod of 6½ to 8 feet rated 2 to 4 weight.
