Approximately 2 miles of double and 1 mile of single bank fishing on the River Irfon at Llanynis some 4 miles from the confluence with the Wye and 3 miles from Builth Wells. The beat averages 30 yards in width and has an excellent variety of water. The wading difficulty also varies - relatively easy in the gravel sections but more difficult over the bedrock. Cefnllysgwynne offers good trout and excellent grayling fishing, with the possibility of occasional salmon later in the season. The Irfon rises and falls quickly after heavy rain, usually being fishable within 24 - 36 hours of a flood.

Season rods are flexible and not tied to one day per week. Season rod holders must be aware that day ticket anglers may also be booked onto the water.

An autumn/winter season rod for just the grayling fishing is also available from October 1st to March 14th. Price: £130.

**Trotting a maggot for grayling is permitted from 1st November to 2nd March**

Excellent self-catering accommodation in a 2 bedroom cottage or a 4 bedroom farm house (sleeping 4 or 8 respectively) is available close to the fishing. Please see Cefnllysgwynne Estate, Builth Wells. for more details.

This beat is part of the evening ticket scheme. Half price evening tickets can only be purchased by phone after 1pm on the day of fishing provided the beat hasn't beat booked that day. Fishing is allowed from 5pm.
