Holyhead Breakwater Country Park

Parc Gwledig Morglawdd Caergybi

A seaside country park converted from an old quarry, with a walk along Britain’s longest breakwater; a starting point for climbing Holyhead Mountain.

Holyhead Breakwater Country Park was created on the former quarry from which stone was extracted in the 19th century to build the Holyhead Breakwater. The park has lakes, brickworks ruins, wildflower meadows and a visitor centre café. The adjacent Holyhead Breakwater, about 2.4 km long, is the longest breakwater in Britain; you can walk all the way to the lighthouse at its end and watch the ferries heading to and from Dublin. Coastal paths from the park lead to North Stack and Holyhead Mountain. Entry is free, parking carries a small charge, and a visit takes about 1–2 hours.
