Holyhead Mountain, Anglesey
'The isle of Anglesey is a popular summer holiday destination, and a favourite place for a walk is Holyhead Mountain, on the tip of the island,' explains David. 'Start near the rocky islet of South Stack, topped by its classic lighthouse, then follow the path above the cliffs to North Stack. Return by the same route, or if you're feeling energetic, divert inland to cross the highest point of the mountain. When the weather is clear you can see the Isle of Man and the Irish coast.'
Distance 6 to 9 miles
