I would probably go to a bike park as i dont use them that often. Probably 3 days hill walking or climbing and two on bike if i get the ok to go. ThanksI strongly suggest that you do an internet search on the riding. There are loads of fantastic walking paths along the length of the coast and also inland. We were near St Davids in the SW and we could not find any worthwhile trails that didn't have a "NO Cycling" sign. We met several groups of bikers on hols in the same area all having the same problem.
