Holyhead Breakwater
The UK’s longest breakwater, a Victorian stone arm stretching well over 2 km into Holyhead Bay, with a promenade along the top out to its 1873 lighthouse.
Built between 1848 and 1873 to shelter Holyhead harbour, the breakwater is made from stone quarried in what is now Breakwater Country Park. It’s a Grade II* listed structure, and a promenade along the top leads walkers all the way out to the lighthouse at the far end, with big views of the harbour, the ferries and Holyhead Mountain.
Good to know
Vehicles have been blocked from the breakwater since 2014, but walkers can still use it in good weather. It’s exposed to wind and waves, so avoid it in rough conditions. Parking, toilets and a café are at Breakwater Country Park next door.
