Take the M3 westwards. Come off at Junction 8 onto the A303 westwards towards Andover

Go past Andover into Amesbury. Take a left turning for Salisbury (A345).

You will reach a roundabout a half-mile north of Salisbury with a Park and Ride facility as the left hand turning. Take the second turning on this roundabout, marked The Winterbournes.

Go straight over a smaller roundabout a hundred metres further on and continue for another four hundred metres where you will see a garage marked Ottons.

Take the right turning here and follow the road, which curves to the right, to the end. Wessex Archaeology is at the end of the road.
