Tregennis CoastalWalk

1d
The Tregennis Peninsula offers some of the wildest and oldest coastal scenery in Wales. This stunning 6-mile (9.6km) circular walk starts from the tiny, fjord-like harbor of Porth Clais, just down the road from the city of St Davids. It traces the jagged perimeter of the peninsula along the Pembrokeshire Coast Path, gazing out over the ferocious tidal races of the Ramsey Sound towards Ramsey Island. The geology here is incredibly ancient (Precambrian volcanic rock), creating sharp, jagged headlands. The walk passes active sea-cliff farms, deep hidden 'geo's (inlets), the historic St Justinian's lifeboat station, and the dramatic ruins of a medieval copper mine right on the cliff edge.
Mission Directive / X-Factor
“The Ramsey Sound Tides. The 'X-Factor' is the raw energy of the sea. By simply walking the cliffs above Ramsey Sound, you are staring down at one of the fastest tidal races in Britain (The Bitches reef). Watching the water sustainedly boil and swirl between the mainland and Ramsey Island gives the walk a uniquely powerful, restless atmosphere.”
Hazard Assessment
Tregennis faces straight into the Atlantic and Irish Sea. In poor weather, the wind on the high cliffs can be strong enough to pose a literal blow-over risk.
MITIGATION: Do not attempt the exposed headlands during a named storm. Wear a windproof shell even on sunny days.
The path is rugged and runs very close to the sheer drops, particularly around the ruined copper mine at St Elvis.
MITIGATION: Keep dogs strictly on leads; the edge is often obscured by thick coastal heather and thrift.
