The Welsh coast is one of Britain’s great secrets. The entire 870-mile shoreline is traced by the Wales Coast Path — the first country in the world to offer a continuous walking route around its entire coast. The variety is remarkable: the wild Pembrokeshire cliffs where puffins nest on offshore islands, the vast empty beaches of the Llyn Peninsula, the dramatic headlands of Anglesey, the gentle Gower beaches that were Britain’s first designated Area of Outstanding Natural Beauty.
Pembrokeshire is the crown jewel — sea stacks, blowholes, and coves accessible only at low tide, with St Davids (Britain’s smallest city) holding a cathedral hidden in a valley. Snowdonia’s coast blends mountain drama with the sea — Harlech Castle stands on its crag above miles of dunes. The Gower Peninsula near Swansea offers Rhossili Bay, regularly voted one of Britain’s best beaches, a three-mile sweep of sand backed by the Worm’s Head tidal island. The seafood is excellent — Cardigan Bay crab, Menai Strait mussels, laverbread for the adventurous.
When to go: May through July for wildflowers, puffin season, and the best chance of sunshine. September for quieter paths and dramatic skies.
