The summit of the hill is the site of an Iron Age hill fort known as Badbury Camp. It is roughly circular in shape, most of which was levelled early in the 19th century. It has been suggested as a possible site of the 5th- or 6th-century Battle of Mons Badonicus, where King Arthur defeated the Anglo-Saxons. It is now a wooded area, known locally as Badbury Clump, of roughly nine acres, swathed in bluebells in May and is a well-frequented local recreation area, for walkers and dog-owners. It is now in the care of the National Trust.
It is also frequented by mountain boarders and bikers who use the downhill course built into the side of the hill. This is maintained and improved by local mountain-board club MEBA with the permission of the Forestry Commission.
