Once a haven for smugglers and later a centre for limestone quarrying, Pwlldu is a secluded National Trust bay south of Bishopston. The beach is sand at low tide, backed by a substantial pebble bank and flanked by limestone cliffs which provide shelter from winds. The pebble bank has partially blocked a stream, forming a large pool just behind the beach (Pwlldu translates as "Black Pool"). The beach is approximately 300 yards wide at high tide extending to ½ mile at low tide. Swimming here is generally safe. There are two cottages on the western side of the valley, which were originally inns (The Ship & the Beaufort). Near the top of the cliff on the west side is one of the quarries, now overgrown, which is an unusual place to explore if you can find a way to reach it. Behind the beach, the wooded Bishopston valley extends for about 1½ miles inland to the village of Kittle (which has a pub).
The closest (roadside) parking to the beach is at Pyle Corner, Bishopston (Grid Ref: SS580882) from where Pwlldu Lane leads to the clifftop, thence becoming a track down to the east side of the beach. The total distance is about a mile. Alternative access is via the coastal path from Southgate or Caswell.
There are no facilities here, but there is a small shop at Pyle Corner. Dogs are allowed at all times.
