Three Cliffs Bay is one of the most picturesque and most photographed bays on Gower. The beach is wide and sandy with dunes, high limestone cliffs and a small pebble bank. The Pennard Pill snakes its way across the beach and is crossed by the coastal path by means of stepping stones. Dangerous rips can occur near the pill on an ebbing tide and also in surf conditions, but otherwise swimming is generally safe. Lifeguards patrol end of May to early September (10am - 6pm) during weekends and school holidays only. It's a good location for a day out, and there's plenty to explore.
The closest parking is at Penmaen or Southgate. At Penmaen there is (free) parking either in a small lay-by on the south side of the road, or on Cefn Bryn common on the north side (just across the cattle grid). Public footpaths lead from here to Three Cliffs and Tor Bay. Alternatively, at Southgate there is a car park (attended / P&D) on the cliffs from where the coastal path can be followed (about ¾mile) to the beach. Dogs are allowed at all times.
Just inland on the eastern side are the ruins of Pennard Castle.
