About Holyhead Mountain
Holyhead Mountain is the summit of Holy Island and the highest ground in Anglesey, about two miles west of Holyhead town.
On two sides it drops steeply to the Irish Sea, and the cliffs below it are an important seabird site. In clear conditions Ireland can be made out across the water.

Finding the summit
rock by plinth is highest visible point but higher ground may be hidden under plinth.
The recorded summit point is trig point on circular plinth. That distinction matters on broad or flat tops, where the obvious cairn is not always the true high point.
