St Davids is a village with a cathedral, which makes it a city by the old rule and still a village by every other one. The church sits in a grassy hollow below the street, next to a ruined bishop’s palace. The Pembrokeshire coast around it — Whitesands, St Non’s, the path toward Porthclais — is why two nights is better than a photo stop.
It is not on the way to anywhere else. That is the recommendation. Come here when Cardiff and the castles of the north have been enough city and stone, and you want weather and a path.

The cathedral and the palace
The cathedral is the working church. The palace next door is the ruin, open as a site, and the better silhouette.
St Non’s and the cliff
A short walk to the traditional birthplace of David and a holy well. The coast is the view, not the well.
Whitesands Bay
A beach with a proper horizon toward Ramsey Island. Go for a walk even if you do not swim.
Ramsey, if the sea allows
Boats leave when the weather agrees. Do not build the day around a crossing you have not checked that morning.
