There is a fantastic road (A470) from Merfyr Tidfil upon over the beacon beacons and down onto the A40 the other side. The views are breath taking and at about the highest point there is a burger van located on the edge of a steep valley with an amazing view over a massive part of Wales. Can be wet and cold at times, so be prepared. Also take enough food and drink to keep you going. Not a climb for those who are not reasonably fit!
My Home ride! But there's a lot more to it than just a ride to Brecon and back! There are several routes to explore, also some circular variations of a truly popular route, the area is of outstanding beauty, with some hidden gems yet to be discovered, especially for road cyclist with climbers legs.
Merthyr to Brecon 18, miles a 36, mile round trip. but can easily be turned in to a circular ride of (name your Milage) any distance.
Come see for yourself.
