Carn Llidi

Carn Llidi is a rocky hill at St David's Head that rises distinctly above Whitesands Bay. The summit provides views across the coast and displays traces of various past uses on its surface.

During World War II, the summit served as an early-warning radar station with concrete-reinforced structures and military fortifications remaining visible. Much older traces come from prehistoric times when people lived here and buried their dead thousands of years ago.

The name comes from South Welsh language roots, with 'Carn' meaning a rocky outcrop and 'Llidi' referring to ashes. The area served as a burial and settlement place for people across thousands of years.

A marked trail leads from Whitesands Bay car park to the summit with clear way-finding along the route. The location is straightforward to reach and has basic facilities near the starting point.

The World War II defenses remain surprisingly well preserved, including concrete remnants and a gun pit from machine gun positions. These military remains give insight into coastal air defense history along the Welsh coast.
