Yeah, Langdale was good .. if you were in the Extreme mode .. all others were good for beginners or soft-roaders.
However, I believe it's now closed. The websites down, rumours are the Forestry Commission closed 'em 'cos too many bikers and 4x4'ers were going off piste and into areas that were marked out of bounds. Dunno the 'real' story though .. just heard bits !!!
