Spent last weekend mountain biking in North Wales. It was incredibly wet all weekend with Penmachno Loop 1 being a incredibly exhilarating ride through /in /on waterfalls.... Followed by a cracking spin round Coed y Brennin forest. We stayed here http://www.rynys-camping.co.uk Can honestly say it's a blooming awesome site, very friendly and seem to have thought of everything. Will definitely look to return in better weather.
