The sandbank adjoins the ancient headland of Hengistbury Head and forms a natural barrier between Christchurch harbour and the open sea. The area is designated a Site of Nature Conservation Interest and can only be reached by foot, bicycle or land train from Hengistbury Head or by ferry from Mudeford and Christchurch Quays.

There are about 300 beach huts on the sandbank, and they are unique because it is possible to sleep in them overnight, consequently a community spirit has grown up here.
