Start with Floating Fry (8–10) on a Fish as a single fly. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.

Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

The trout lake is stocked with rainbows and browns. Accessible from London and the Home Counties. Day tickets. The fishery reopened under a new website in 2026 and says all fishing is strictly catch and release, the trout included, so there's no kill ticket.
