  • Island Summary:

    The circular walk around Holy Island, Anglesey, is one of the best sections of the Wales Coast Path. With a dramatic coastline, impossibly located lighthouses, powerful tidal races and spectacular bird life this is a walker’s  paradise. This walk passes the port of Holyhead and its breakwater, one of the longest in Europe before heading up the flanks of Holyhead Mountain, the highest peak in the county of Anglesey. It passes the the two tiny islands of North Stack and wildlife-filled South Stack, and takes in the spectacular sea arches near Rhoscolyn as well as the larger sand beaches at Trearddhur Bay and Penrhos Country Park. The route can be completed in a day, or broken down into two days – as there is so much to see.

  • Look out for:
    • Bwa Gwyn sea arch
    • Precipitous views of South and North Stack islands
    • Hidden beaches
    • History and wildlife of Breakwater Country Park
  • Route description:

    The Anglesey Coast Path on Holy Island officially starts at St Cybi’s Church in Holyhead. It initially leads passed the ferry port – the gateway to Ireland before heading up to Holyhead Mountain. Here you pass an old Iron Age hill-fort,  eventually leading to the famous South Stack lighthouse and Twr Elin – a popular spot for bird-watchers. Further on, the path drops from the cliff tops to beaches like Porth Dafarch and Trearddur Bay and rugged coastline and the healing-well and sea arches near Rhoscolyn and on to Silver Bay. Here the path veers inland through the gorse and quiet lanes to Four Mile Bridge. After crossing the bridge back to Anglesey, the Wales Coast Path is followed underneath the A5, where the walk then returns to Holy Island via the Stanley Embankment and then Penrhos Park.

  • Getting there:

    Holyhead is easy to get to with a train station, numerous buses and even an airport at Valley (Anglesey) with flights to Cardiff.
