The beach is bordered by a dune system that has formed over thousands of years, covering evidence of earlier coastal shifts.
The adjacent Bosherston Lily Ponds are internationally recognized for their rare freshwater wildlife and expansive displays of white water lilies in summer.
During the Second World War, the beach and surrounding dunes were used by the British military for D-Day landing training exercises.
The beach is tidal; the wide expanse of sand at low tide reveals rocky outcrops and deep-water swimming areas, while the beach significantly narrows at high tide.
Broad Haven South Beach is a secluded, expansive sandy beach located within the Pembrokeshire Coast National Park. It is distinguished by the dramatic limestone cliffs that flank the bay and the freshwater stream that bisects the sands. The beach is backed by the Bosherston Lily Ponds, a series of man-made lakes created by the Cawdor family in the 18th and 19th centuries. The landscape is part of the Stackpole Estate, managed by the National Trust. The site offers extensive dune systems and access to the Pembrokeshire Coast Path. It remains one of the few beaches in the region with significant freshwater influence, supporting diverse aquatic vegetation and local bird life.
