Snowdon is the centerpiece — summit by the Pyg Track for the walker’s version, or the Snowdon Mountain Railway for the more comfortable one, both arriving at Wales’s highest point with views across to Ireland on a clear day. The Llŷn Peninsula to the west is quieter and less visited: a Celtic promontory of coastal walks, small beaches, and a light that photographers chase. Conwy Castle and Caernarfon Castle anchor the medieval history of the north — both are among the best-preserved Edward I fortifications in Europe.

The Pembrokeshire Coast Path runs 299 km along some of the most dramatic coastal scenery in Britain: red sandstone cliffs, sea stacks, seal colonies, and coves accessible only on foot. The full path takes two weeks; select sections can be walked as day stages. St Davids is the smallest city in Britain and worth its detour — cathedral, bishop’s palace, and a surf beach ten minutes away. Tenby is the classic Welsh seaside town done well: Georgian harbor, medieval walls, and the Caldey Island ferry.

The Brecon Beacons offer a different Welsh landscape: open moorland, waterfalls, and the Black Mountains’ long ridgelines. Hay-on-Wye — the town that declared itself an independent kingdom and became the world’s second-hand book capital — sits on the English border and is worth an afternoon for the right traveler. The Elan Valley reservoir landscape in mid Wales is largely undiscovered: Victorian Gothic dams, red kite country, and a silence that feels genuinely remote despite being two hours from Cardiff.
