Just wanted to say thanks to everyone for their excellent advice.
We had a couple of problems with the car which didn't help and the weather was pretty poor at points but we had a wonderful time and have plenty of things that have been added to our must do list for our next visit.
A special thank you to Phil1960 who was a huge and appreciated help.
We're really falling in love with the Brecon Beacons. Excited to go back once the colours change in the Autumn.
Thanks a lot guys, you're all great folks.
