The Afon Efyrnwy is a clear, fast-flowing Welsh border river that offers excellent sport for trout and grayling anglers, with productive stretches through varied terrain including moorland and woodland sections. The upper reaches are typically shallow and rocky, ideal for dry-fly fishing, while lower sections deepen and slow, holding larger fish. Access is available through various fishing associations and landowner permissions, particularly around the Montgomeryshire area, though advance arrangement is recommended.
