Which channel separates Wales from southwestern England?

The Bristol Channel separates Wales from southwestern England.

It extends inland from the Celtic Sea and reaches the mouths of the Rivers Severn, Avon, and Usk. The channel’s shores include the Welsh counties of Pembrokeshire, Glamorgan, and Gwent, as well as Devon, Somerset, and parts of North Devon in England.

Bristol, the historic port city that gives the channel its name, lies at the head of the Bristol Avon. The waterway has one of the world’s largest tidal ranges; the Severn Estuary nearby is especially famous for dramatic changes in water level.

The Bristol Channel is not the same as the English Channel, which separates southern England from northern France. Nor is it St George’s Channel, the passage between Wales and Ireland. Its broad shape and powerful tides have influenced ports, fishing, navigation, and proposed tidal-energy projects.
