Not that far from Caesar’s Camp Hill Fort four ‘tumuli’ are marked on the map just to the SU822493. At a quick look this may also be ‘sensitive’ ground and there was no obvious place to park. I’ll hopefully return another day and take a closer look.
The Hampshire County Council website says that they are a Scheduled Ancient Monument - “Five bowl barrows situated at Heath Brow, east of the B3013. The group is sited in heath land among pine trees, bracken and heather”
The website also mentions occupation and finds in the area - “Many mesolithic implements found including scrapers, saws, long blades and two axes. Several other sites noted in the area, though some have been obliterated. Some finds in Willmer House Museum, Farnham.”
