The Irfon runs for some 30 miles through wonderfully scenic Welsh countryside from its source in the Cambrian Mountains beyond Abergwesyn, to Builth Wells where it joins the river Wye, renowned for its salmon fishing.

The Irfon is well known for its superb grayling and excellent wild brown trout fishing, with once again after a gap of around 20 years, an opportunity to catch salmon when the water is right. Salmon are now regularly seen in the river.
Fishing on the Cwm Rybyn beat
The Cefnllysgwynne beat flows through the woods and meadows of the estate and averages 30 yards in width with good vehicle access and relatively easy wading for the most part but a wading stick is advisable on rocky areas. Where the river runs through woods, the banks can be quite steep and overgrown but a footpath is kept open along the whole length of the home bank. Find an easy place to enter and then wade up or down to your preferred fishing area. The far bank can be accessed in lower water via two fords - and for the more adventurous, elsewhere with some rock hopping. Vehicles can be driven close to the river on hard core tracks and in drier conditions to the river bank itself.

The beat offers good trout and excellent grayling fishing with the possibility of a salmon, usually later in the season although rain early in the season can increase salmon prospects in the summer and early autumn. Day and season tickets are available. See Bookings below. There is plenty of variety with 18 named pools ranging from deep, fast flowing, narrow rocky gutters through slower flats with lovely rocky ripples at the top running into ever changing

gravel banks with overhanging trees below, to deep slow moving pools with frequent rocky lies.

The flats, gravel banks and runs are excellent opportunities for grayling. Twelve of the deeper pools are decent bets for salmon later in the season and seven are deep enough to hold an occasional spring or summer run fish through most of the season. The Irfon rises and falls quickly after heavy rain, usually being fishable within 24 - 36 hours of a flood
Two holiday cottages on the estate can be booked with the fishing or on their own, subject to availability, see separate websites Hafod-y-blodau and Hendre Farm House. The cottages are well positioned for use as a base for fishing elsewhere in central and south Wales as well as on this beat. Local fishing on the Wye and Usk and their tributaries and the Teme, Towy, Teifi and Taff (giving access to sea trout as well as salmon, trout and grayling) as well as some still waters can all be booked direct through the Wye and Usk Foundation at This web site also includes catch reports and water conditions for the local area.
Fishing can be purchased for up to 5 rods at £22 per rod per day (all species). To make a booking, please email with your requirements. If you just wish to investigate fishing options in the local area, please provide a telephone number and we will ring you back. A detailed plan of the fishery with access routes and notes on the main pools will be sent or emailed once booking and payment has been confirmed.
