Navigation

There are no road or rail crossings of the Bristol Channel so direct crossings are necessarily made by sea or air, or less directly by the road and rail crossings of the Severn estuary.

Because of the treacherous waters, pilotage is an essential service for shipping. A specialised style of sailing boat, the Bristol Channel Pilot Cutter, developed in the area.

Surfing

Much of the coastline at the western end of the Bristol Channel faces west towards the Atlantic Ocean meaning that a combination of an off-shore (east) wind and a generous Atlantic swell produces excellent surf along the beaches. The heritage coasts of the Vale of Glamorgan, Bideford Bay and Gower are, along with the Atlantic coasts of Pembrokeshire and Cornwall, the key areas for surfing in the whole of Britain. Although slightly overshadowed by the Atlantic coasts of North Cornwall and West Pembrokeshire, both Gower and Bideford Bay nevertheless have several superb breaks—notably Croyde
