The White Cliffs of Dover are a series of chalk cliffs on the English Channel coast in southeastern England. They stretch for about 16 kilometers (10 miles) along the coast between the towns of Dover and Deal in the county of Kent. The cliffs are made up of pure white chalk, which gives them their distinctive appearance and has made them an iconic symbol of Britain.

The cliffs are up to 350 feet high in places and offer spectacular views across the English Channel to the coast of France, which is just 21 miles away at its closest point. The cliffs have played an important role in British history, providing a natural defense against invaders from across the Channel.

In addition to their historical and cultural significance, the White Cliffs of Dover are also a site of ecological importance. The chalk grasslands that cover much of the cliffs are home to a wide range of plant and animal species, including many rare and endangered ones.

The area around the cliffs is also popular with hikers and walkers, with a number of trails and paths offering stunning views of the cliffs and the surrounding countryside.
