Not the longest or hardest ride by a long chalk, but certainly one of the most scenic. Beautiful trails along the side of the Bosherston Lily Ponds, narrow bridges over the ponds to cycle over, then St Govan's head, through the trail on Castlemartin Military firing range (check live firing times before you go) along the top of some stunning craggy coastline to Stack rocks which was covered in seabirds.
Absolutely stunning.
