Our verdict
Worth a stop for the barrows if you're interested in prehistoric Cranborne Chase, though it's a quiet, unmarked spot rather than a waymarked walk. Livestock graze nearby, so dogs on a lead.
CRoW downland near Tarrant Gunville, close to the Dorset Cursus — the huge Neolithic monument that runs for 10km across Cranborne Chase — and the Bronze Age barrow group at Thickthorn Down itself, a scheduled group of round barrows visible as low mounds in the grass.
