Holyhead Mountain
Mountain Highest point on Holy Island, coastal cliffs and views
The highest point on Holy Island off Anglesey, reached via a coastal footpath. Walkers come for cliffside routes, seabird colonies and the remnants of Iron Age field systems on the slope.
Holyhead Mountain is the highest point on Holy Island off the northwest coast of Anglesey in Wales, reaching roughly 220 metres above sea level. It is a prominent coastal hill on the island.
The area offers coastal walking routes with sea cliffs and wide views over the Irish Sea, and it is frequented by walkers and nature observers for the exposed ridge-top paths and maritime scenery. The summit and slopes are open access and form part of local outdoor recreation.
The mountain and surrounding coastal landscape were shaped by coastal erosion and glacial processes and have been used historically for grazing and local transit. Today it remains a natural landmark closely associated with the town of Holyhead.
Holyhead Mountain sits on Holy Island, immediately adjacent to the town of Holyhead and separated from mainland Anglesey by a short causeway and harbour.
- Height and walking: Highest point on Holy Island (Anglesey) at about 220 metres, offering coastal walking routes and exposed ridge-top trails to the summit.
