St Brides Bay

St Brides Bay (Welsh: Bae Sain Ffraid) is a bay in western Pembrokeshire, West Wales.

Either Skomer Island or the mainland extremity of Wooltack Point at the western end of the Marloes Peninsula marks the southern limit of the bay whilst its northern limit is marked by Ramsey Island off St David's Head. The mouth of the bay is about 7 miles (11 km) wide and extends some 10 miles (16 km) eastwards from this line.
