I’m a fan of the Gap, and Brecon riding overall, but we stay here instead;

Lovely food, a really warm welcome, and great beer. Everything you could want from a pub to ride from.
Then, after a few over dinner, we head down the road here;

Often have some great music, always have some superb beer, always have some great banter.
Last trip to the Star saw the Squadron discover that they also have an excellent range of single malts. Hang. Over. HARD! 🙂
The Gap is lovely riding, especially if, heading DH North back to Brecon, you turn right after the gate down a BW that it strewn with babyhead rocks. Killed a frame of one of my chums a few years ago, but it’s an amazingly good little addition.
