Its land area of 110 mi2 (285 km2) stretches 12 miles (20 km) from east to west and occupies the Llynfi, Garw and Ogmore valleys.

It includes all of the former Ogwr borough apart from the communities of Wick, St Bride's Major and Ewenny, which went to Vale of Glamorgan.

It is one of the finest wildlife habitats in Wales,[citation needed] and one of the last remnants of a huge dune system that once stretched along the coast from the River Ogmore to the Gower peninsula.
