Llyn Brenig venue rules

Trout fishing on Llyn Brenig itself is fly only. Pike anglers must book at least one day in advance and follow the fishery's separate pike etiquette and terms. The current pike guidance allows fishing from designated shore pegs or hire boats during the published season, with overnight pike pegs running from 6pm to 7am. The fishery can close for restocking or major competitions, so booked availability is controlled through its fishing calendar.
