Chesil beach is one of the most unusual beaches you will find anywhere in Britain. Stretching nearly 17 miles from Portland to West Bay the beach is comprised of a huge bank of pebbles. The beach is unnaturally straight and consistent along its length with a height of 50 feet (15m) and width of 600 feet (180m). What doesn\’t remain the same along the length is the pebble size which are bigger at towards Portland.
The eastern portion of the Chesil bank backs onto Fleet Lagoon, which is where Barnes Wallis’s bouncing bomb, as used by the Dambusters in World War II, was tested. These days the Fleet is an important conservation area and unique habitat.
