Pembrokeshire Coast National Park, Wales: Porthgain to Whitesands

This 9.7-mile segment runs from a tidy harbor village to a vast beach, and ends only two road miles from a don’t-miss sixth-century church and museum in St. Davids.

From Porthgain’s stone piers, head south to the secluded beach of Traethllyfn, where seals often bask on the black sand. Continuing past the tiny village of Abereiddy, you’ll walk between the Irish Sea and electric-green pastures where shaggy, curved-horn highland cows graze behind ancient stone fences overgrown with yellow gorse. After 6.6 miles, spot the point of St. David’s Head above Whitesands Bay, with Ramsey Island looming beyond.
