Part of the River Taff, running through Cardiff
The River Taff (Welsh: Afon Taf) is a river in Wales. It rises in the Brecon Beacons as two rivers, the Taf Fechan ("little Taff") and the Taf Fawr ("great Taff") before becoming one just north of Merthyr Tydfil. At Cardiff, it empties into the Bristol Channel.
The river supports several species of migratory fish, including salmon, sewins (sea trout), and eels.
