Holyhead Mountain Circular Walk

The circular walk from Holyhead town over Holy Mountain (Mynydd Twr, 220 metres) and back via the coastal path is one of the most rewarding short hikes in North Wales — a 4-mile loop with 360-degree views stretching from Snowdonia to the Wicklow Mountains of Ireland on clear days.

Rhoscolyn Coastal Walk

The 4-mile headland loop from Rhoscolyn village on the southern tip of Holy Island follows the Anglesey Coastal Path around a dramatic sequence of quartzite sea cliffs, natural rock arches — most famously the Bwa Du (Black Arch) and the pale Bwa Gwyn (White Arch) — sheltered coves, and wild cliff-top heathland before returning through farmland past the 6th-century holy well of St Gwenfaen, which local tradition held could cure mental illness through ritual offerings of white quartz pebbles.

Llanddwyn Island Walk

The walk from Newborough Beach across the dunes and along the shore to Ynys Llanddwyn — a narrow tidal promontory jutting into Caernarfon Bay — takes in one of Wales's most romantic landscapes, combining white sand, Corsican pine forest, and a ruined 16th-century church dedicated to St Dwynwen, Wales's patron saint of lovers whose feast day falls on 25 January.

Mynydd Bodafon Walk

Mynydd Bodafon (178 metres) is Anglesey's highest inland summit — a heather-and-gorse moorland ridge of ancient Precambrian quartzite rising abruptly from the flat farmland of the east coast, with views from the trig point that stretch to the full Snowdonia skyline, the Llŷn Peninsula, and on exceptionally clear days the Wicklow Mountains of Ireland.

Near Amlwch, Anglesey

Parys Mountain

The summit plateau of Parys Mountain (146 metres) above Amlwch presents a landscape so extraordinary it was used as a stand-in for Mars in early film productions — a post-industrial moonscape of ochre, rust-red, violet and acid-green spoil heaps pocked with mineral-stained pools, the skeletal remains of an 18th-century windmill, and the sheer walls of the Great Opencast, an excavation so vast it is visible from the main road miles away.
