About this water

The Coln runs through some of the prettiest Cotswold villages — Withington, Fosse Bridge, Bibury, Fairford — to join the Thames near Lechlade. The Bibury beat is famously associated with Bibury Trout Farm and the village's chalk-stream identity. Mixed wild and stocked brown trout, grayling on some beats. Mostly private but Bibury area accessible via the trout farm structure.
