The tiny River Alun enters the sea at Porthclais, which was once an important port for St Davids and the surrounding area. The steep-sided inlet is protected by a harbour wall at its entrance, and has a small low-tide sandy beach just ouside. It's a popular venue for kayaking, scuba diving and sailing. East of the harbour, a rock slab provides good training for novice climbers. Facilities include a P&D car park, toilets and a small tea room.
The photos were taken at low tide.
