Rewarding expedition from the county town of Dorset through the pre-historic landscape of the Dorset Downs with splendid views out to the Jurassic Coast from the South Dorset Ridgeway.
Maumbury Rings, an ancient British henge earthwork converted by the Romans for use as an amphitheatre (the largest of its kind in Britain), is walked through early on. Then Maiden Castle, the largest – and one of the most complex – Iron Age hill fort in Europe, with its up to four banks and three ditches and remains of a Romano-Celtic temple, is explored in detail. Settled from 4000 BC, it was one of the most powerful settlements in pre-Roman Britain, the Durotriges were the last tribe to have lived there.
From there the route follows the narrow South Winterbourne Valley to lunch in Martinstown before a long ascent up to the heathery Black Down, crowned by the 22m-high Hardy Monument (to Sir Thomas Hardy the Admiral, not the writer), with some stunning views to the Jurassic Coast and the Isle of Portland. Continue with views out to sea atop Bronkham Hill, with an interesting group of barrows and shakeholes on its ridge. On the descent from it you pass more barrows, en route back to Dorchester.
A long extension adds more pre-historic highlights – the Valley of (Sarsen) Stones, one of the finest examples of a boulder ‘train’ in Britain, several impressive barrows and two stone circles – and leads through the very pretty Bride Valley.
You can omit parts - or all - of the loop through Maiden Castle: cut up to 2.3 km and 75m ascent.
You can omit the final ascent to the Hardy Monument: cut 1.1 km and 50m ascent.
You can add a ‘pre-historic’ loop from the Hardy Monument via the Valley of Stones, Littlebredy and various Stone Circles and Barrows, adding up to 13.1 km (8.2 mi) and 477m ascent/descent to the walk. This includes 1.0 km of optional out-and-backs to Bridehead Lake & Waterfall and to a couple of Barrows, as well as an option to cut out 1.1 km distance and 78m ascent between the Valley of Stones and Littlebredy. The resulting very long walk should take about 9 hours net to complete.
An Alternative Ending at Portesham (then bus to Weymouth) enables two more variations:
