Rossett & Gresford Flyfishers (day ticket via Fishing Passport)
2.5 miles from the railway bridge at Rossett upstream to Wormswood, Gresford — founded 1906, one of the oldest continuously-running clubs in Wales. Wild brown trout throughout; grayling established here since 2008 and now breeding. Migratory salmon and sea trout are seen scaling Rossett weir most years but rarely dwell — not a targetable run.
Day ticket £20/rod (2026 pricing). Fly-only, barbless hooks, no dogs, wash-off biosecurity policy applies.
