Bullslaughter Bay caves

Pembrokeshire Coast Path from St Govans to the Green Bridge of Wales

At Bullslaughter Bay, the Dinantian age Carboniferous Limestone Series has been eroded along folds and fractures into a series of sea caves and sea stacks. The main structure is the Bullslaughter Bay syncline, the axis of which runs from near the caves on the left of the photo and crosses the sandy beach.

Some of the fractures are filled with orange-brown, angular brecciated sediment ('Collapse Breccia'), thought to be of Triassic age.
