The Afon Clywedog is a productive mixed fishery in North Wales, flowing through varied terrain with both fast runs and slower pools that hold good populations of trout and grayling. The river offers excellent sport for fly fishers on its upper reaches and increasingly good coarse fishing downstream, with reasonable access from several public footpaths and bridges. Most of the river requires permits from local angling clubs or the riparian owners, so checking locally before fishing is essential.
The statutory close season on Afon Clywedog runs 15 March – 15 June (rivers, England & Wales). No coarse fishing is permitted during this period. Beyond the rod licence, fishing rights on Afon Clywedog are typically held by local angling clubs — check with the relevant club or day ticket provider before visiting.
