The Strait of Dover or Dover Strait is the strait at the narrowest part of the English Channel. The shortest distance across the strait is from the South Foreland, 6 kilometres (some 4 miles) northeast of Dover in the county of Kent, England, to Cap Gris Nez, a cape near to Calais in the French département of Pas-de-Calais, France. Between these two points lies the most popular route for cross-channel swimmers as the distance is reduced to 34 km (21 mi).
