The River Clwyd is one of Wales's premier sea trout rivers, flowing northward through the scenic Vale of Clwyd in North Wales. Rising in the Clocaenog Forest northwest of Corwen, the river travels through a relatively narrow valley before broadening into a wide agricultural vale as it passes through Ruthin and continues toward the coast. The catchment is characterized by a mix of intensive arable and dairy farming in the fertile lowlands and mixed sheep and beef farming in the upland reaches. The river is slow-moving and meandering through much of its lower length, while the upper reaches and tributaries — particularly the River Elwy — can be extremely flashy, responding rapidly to heavy rainfall and experiencing significant low flows during dry periods. The Rhyl and St Asaph Angling Association manages fishing on the River Clwyd and its tributaries, the River Elwy and River Aled, controlling 21 river beats within easy reach of North West England. The Vale of Clwyd Angling Club also manages several beats along the river system, making this a well-organized and accessible fishery for visiting anglers.
