Highdown Hill is a prominent hill in the South Downs, as its name suggests, reaching a height of 81 metres (266 ft). The summit of the hill and its western slopes lie in the parish of Ferring in the Arun district, while its eastern slopes lie in the borough of Worthing. It is a popular spot for picnickers, dog-walkers and local riders. It overlooks Littlehampton, Angmering, Ferring and Worthing with views, when the weather is good, east as far as the Seven Sisters and west to the Isle of Wight. It is the property of the National Trust. To the north the ancient hill forts of Cissbury Ring and Chanctonbury Ring can be seen, and the remains of an ancient hill fort exist on the summit of Highdown Hill.
