St Davids occupies the far western tip of Pembrokeshire as the smallest city in Britain. This historic site sits within a hollow to hide the great cathedral from coastal raiders. The massive building was crafted from local purple sandstone and stands near the ruins of the Bishop’s Palace. My top tip is to visit the holy well at St Non’s Chapel on the cliff edge. You can watch the Atlantic swells crash against the jagged rocks. Porthclais Harbour remains a narrow, tidal inlet where small boats rest on the mud at low tide. Rare choughs fly over the high coastal paths scented with wild gorse. Life here is quiet and tied to its deep spiritual roots.
