A really nice bit of scenary and a pretty good road that follows the Wye up from the Severn crossing to Monmouth. Easy access from the M48 J2
A very fast and twisty 14k run. Can be combined as part of: Leave Brecon and take the A470 south towards Merthyr branching off onto the A4059 for a a very fast twisty 11 miles down into Hirwaun. From the roundabout take a left on the A465 back east to the A470 then south again past the Merthyr viaduct all the way down past Pontypridd - great chance to open up the bike for a few miles just watch out for the cameras now and then! Take the Caerphilly exit left onto the A468, up the hill (speed camera) then right onto the A469 (mountain road) for a great little blast over the mountain topbefore home - Travellers rest pub a great place to stop for a pint and some food. Follow this road down into Cardiff centre or, like me, if you live in North Cardiff take a left just before the bridge over the M4 for a drive through lisvane lanes and home!
