Follow the A36 into Salisbury. Go straight over the first roundabout

At the second roundabout, take the second exit (right) onto a short dual carriageway.

At the third roundabout take the second exit, onto another short dual carriageway (signposted Warminster/Bristol).

At the fourth roundabout take the third exit (right) onto Castle Road (signposted Amesbury)

You will pass out of Salisbury, past Old Sarum hillfort on your left, and after a few hundred metres you will come to a roundabout with the left hand turn marked for Amesbury and Stonehenge, the middle one for a Park and Ride facility and the right-hand turn marked The Winterbournes. Take this last turning.

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.
