Colin’s Burger Van! If you are ever riding along the A470 just North of Merthyr take a stop in the layby alongside the Llywn Onn Reservoir. It’s picturesque at any time of the year, just on the edge of the Brecon Beacons National Park. It is also the place where you will find sustenance & refreshment at Colin’s Burger Van. Here is Colin….. but I don’t know who the fat bloke in the yellow jacket is…. eating all his profits….. Pay Colin a visit. Bikers are always welcome.
