- Not to be confused with River Taff
The River Taf is a river which rises in the Preseli Hills of northern Pembrokeshire and flows approximately 30 miles through Carmarthenshire to Carmarthen Bay. It is one of three rivers, along with the River Gwendraeth and River Towy, to enter the sea on the east side of Carmarthen Bay.
Water drains from high ground above the village of Crymych in Pembrokeshire, and at one time flowed at ground level across the main Cardigan to Tenby road (now the A478) before falling to the level of the defunct Whitland and Cardigan Railway station Crymmych Arms (Great Western Railway) where, on the Ordnance Survey map of 1866 it is shown as the source of the Taf.
At this point the stream fulfils its description "Crymych" (Welsh for "crooked stream") by turning through almost a right angle along the floor of the valley.
The stream is mentioned, with various spellings, in records since 1468 and provided both the village and its hostelry with an identity. From there the Taf, augmented by numerous minor tributaries, flows east-south-east to Llanfyrnach then south-west through Glandŵr, Llanglydwen and Login to Whitland. It then flows east to St Clears, south of which its broad estuary meets Carmarthen Bay near Laugharne.
The length of the river is about 35 miles from Crymych to Ginst Point, of which about nine miles are tidal.
