Hillside Scout Campsite is the official campsite for Adur Valley District Scouts, established in September 1937 on 21 acres at the foot of the north side of the South Downs in Sussex.

Set within ancient woodland, the site offers direct access to the South Downs and can be reached on foot via hiking trails. The campsite welcomes Scout and Guide groups, youth organisations such as Duke of Edinburgh and Cadets, schools, and outdoor providers.

It features a large cut field, a meadow camping field, and a wilder untamed area, making it suitable for groups of various sizes. It serves equally well as a weekend camp destination or a Duke of Edinburgh hike stopover.
