St George's Channel

St George's Channel runs between southeastern Ireland and southwestern Wales, linking the Irish Sea to the Celtic Sea and Atlantic approaches. Ships sailing between Dublin and ports farther south pass through this waterway, while shorter crossings connect the coasts on either side. Headlands and islands offer landmarks, but the channel is exposed to winds and tides that can make the passage difficult. Its position made it a route for merchants and fleets moving between the western coasts of Britain, Ireland and the wider ocean.
