W&U beats:
The Monnow at Skenfrith is a lovely beat. I have only fished the Monow Valley beat once (with high water) but river access there is definitely more awkward. There are many posters here with much more Monnow experience, and I'm sure they could offer good pointers.
Last season I fished the Usk at Pantyscallog, Llandetty, Buckland, Glan yr Afon and Bridge Meadow, as well as a handful of times on private water just below Brecon. All different, all lovely.
If I could only pick two W&U beats this coming season, they would be Llandetty and Glan yr Afon for beauty and variation in water....but this is only my opinion, and I havn't yet fished them all!
I think the Usk is my perfect river...just the right size, usually wadable, not too 'manicured' but not a major battle for access either. The brown trout are really beautiful. I usually see a Kingfisher, sometimes a Red Kite, often Buzzards, once a Sparrowhawk. The countryside here is a true joy.
Tightlines.
