Geography

Jersey is the largest of the Channel Islands, lying approximately 160km (100 miles) south of the coast of England and 23km (14 miles) from the coast of Normandy in France. The island is roughly 14.5km (9 miles) by 8km (5 miles). It slopes from north to south and often appears to visitors to be largely composed of pink granite. Jersey has over 20 bays, many small harbours and magnificent beaches bathed by the warm waters of the Gulf Stream.
