Surely you've heard of the White Cliffs of Dover. This picturesque slice of English coastline faces the Strait of Dover and France. All eight miles of cliffs are the perfect complement to this little town. The white cliff face is due to its composition of chalk and gave rise to a popular World War II song, "There'll Be Bluebirds Over the White Cliffs of Dover." The song was written after the Brits and the Germans fought over these cliffs in the Battle of Britain. The bluebirds actually allude to the British fighter pilots in their blue uniforms. Because the town is on the small side, the cliffs of Dover are easy to access -- just head towards the sea and look up!
