The Holyhead Breakwater, which protects the marina, is approximately 1.5 miles long, making it one of the longest in the British Isles.
The harbour was historically used as a primary packet station for mail ships travelling between London and Dublin.
The marina sits on the site of the historic Newry Beach, which was once a popular bathing spot for local residents.
The breakwater construction was completed in the 1870s and involved the use of massive stone blocks quarried locally from Holyhead Mountain.
Marina Caergybi is a protected, deep-water marina situated within the breakwater of Holyhead Harbour on the Isle of Anglesey. It provides a sheltered basin for vessels, shielded from the Irish Sea by one of the longest breakwaters in the United Kingdom. The site is adjacent to Newry Beach, offering direct access to the coastal walking paths that fringe the town. The facility serves as a primary hub for maritime transit between Wales and Ireland. The surrounding area preserves a history of industrial maritime activity, marked by stone sea walls and heritage architecture.

Check the tide charts before visiting, as the character of Newry Beach changes significantly between high and low tide.
Bring wind-resistant clothing, as the exposed coastal position frequently results in high winds regardless of the season.
Walk the full length of the breakwater for an unobstructed view of the harbour and the Irish Sea.
Attempting to swim near the main harbour entrance due to strong tidal currents and heavy ferry traffic.
Avoid obstructing active boat mooring areas and respect private vessel boundaries.
