Pembrokeshire is the most coastal county in Wales and has some of the finest cliff walking in Britain. The Pembrokeshire Coast National Park covers most of the shoreline, and the county also has quiet hills inland.

The Pembrokeshire Coast Path. The 186-mile National Trail runs from Amroth in the south to St Dogmaels in the north, passing sea cliffs, sandy bays, seabird colonies and offshore islands. Barafundle Bay and Stackpole Quay in the south, Broad Haven and Marloes in the west, and Whitesands Bay and St Davids Head in the north-west are among the best-known sections.

St Davids, Fishguard and Newport. St Davids is Britain’s smallest city, built around its cathedral, with the coast just a short walk away. Fishguard has a harbour and coastal views, while Newport sits beneath Carn Ingli, a hill with ancient hillfort remains.

Tenby and the south. Tenby, with its medieval walls and harbour, is the main resort, and Narberth, Haverfordwest and Milford Haven are good bases for inland and estuary walks around the Cleddau.

The Preseli Hills. The open moorland of the Preselis, the source of the bluestones at Stonehenge, offers long, quiet ridge walks.

Cliff paths can be eroded and unstable, so stay away from the edge, and check tide times before walking on beaches.
