At this point the stream fulfils its description "Crymych" (in Welsh "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 ESE to Llanfyrnach then SW 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. Its length is about 56 km (35 mi) from Crymych to Ginst Point, of which about 14 km (9 mi) is tidal.
