Good news for you there is a wall section at Glentress in the Freeride Park - sadly as I was doing Black & Red routes in the same day did not have time to try the freeride park I figured Ewok village was enough
Seem to be a lot of tyre tracks on the ground beneath...wonder why?
Steve and I saw something like this in the Coed-y-Brenin car park last weekend - but a lot shorter. It wasn't until we saw some children playing tunes on it that we realised it was nothing to do with MTBing
