Llangennith sits on the far west of the the Gower Peninsula in South West Wales. One of Wales' finest beaches, the wide sandy beach of Rhossili Bay, lies 1 mile west of Llangennith. There are superb walks from Llangennith with fine views of Worm's Head and the Gower coastline. It is a perfect spot for rock pooling, fishing, surfing, bodyboarding and swimming.

The village has a scattering of houses, a surfing shop, and one pub - the Kings Head. The parish church, dedicated to St Cenydd, was founded as a monastery, and later became a priory. Legend has it that, as a crippled baby, St Cenydd was put into a river in a willow cradle but was washed ashore. Two sea-birds cared for him by plucking themselves in order to make a nest for the baby. He was fed by a deer who came to him every day and squirted milk into a bell which had been delivered by an angel. At one time, the Swansea Church contained a stained-glass window depicting St Cenydd as a one-legged man with a deer and a seagull for company.

Rhossili and Port Eynon lie to the south, and the villages of Cheriton and LLanmadoc to the north east.
