Distances are to the start of each walk, straight-line from the centre of Castlemartin. Several of these cross grazed clifftop with an unfenced drop — dogs on leads, and if cattle come at you while you’re holding one, let go. In an emergency anywhere near the coast, dial 999 and ask for the Coastguard.
