Porthselau is a small cove south of Whitesands Bay. Access from the coastal path is down a few steps cut into the rock. The beach is sandy at low tide and flanked by cliffs of sandstones and conglomerates. It is generally safe for swimming and on very low tides it is possible to walk along the shore to Whitesands bay. Pencarnan campsite is situated behind the beach, and there are many other camping sites locally. A private P&D car park is located on the St Davids - St Justinians road with some free lay-by parking towards the very end of the road. From the car park a public footpath runs through the campsite to the beach. Alternative parking is at Whitesands.
Dogs are allowed at all times.
