This Dorset beach is one of three major shingle beach structures in Britain.

Its name is derived from the word chessil, meaning "gravel" or "shingle". Within its 18 miles is some of the best free fishing in the UK.

During late spring and early summer, mackerel shoal along the whole of the beach in great numbers. Most people target them with a feather rig which can be bought cheaply from all tackle stores.

Mackerel are most easily caught during daylight in calm weather and can come very close to the shore as dusk approaches. Look for signs of seagulls diving into the sea
