Barafundle Bay is a remote, slightly curved, east-facing sandy beach near Stackpole Quay and is part of the Stackpole Estate, managed by The National Trust. The beach, as the whole Stackpole Estate, used to be owned by the Cawdor family of Stackpole Court and was their private beach. On the northern approach to the beach are steps and a wall which were built by the owners to ease access to the beach SR9995 : Entrance to Barafundle Bay.
Behind the beach are a series of sand dunes.
The bay is only accessible by foot, either from Stackpole Quay or Broad Haven. The bay also marks the geological boundary between the Carboniferous Limestone to the south and the Devonian rocks to the north.
