The Canal de Calais, also known as the Strait of Dover, is a narrow body of water that separates England from France. It is approximately 21 miles (34 kilometers) wide at its narrowest point and serves as a crucial shipping route for vessels traveling between the North Sea and the Atlantic Ocean. The canal is famous for its historical significance and scenic views. It is home to the White Cliffs of Dover on the English side and the Cap Gris-Nez on the French side. The area is also a popular spot for ferry services, connecting Dover and Calais.
