Visited 20.6.10.
Driving along the A48, past Caerwent Roman Town (great place to visit), the barrow is on your left in a field just before the railway bridge. Parking is difficult although there is a bus stop you can park in on the opposite side of the road. Be careful crossing as this is a busy road – even on a Sunday. In the field were various ‘shacks’ and a couple of horses. There was waist high grass / vegetation all along the side of the railway embankment and I couldn’t make out anything obvious. No doubt this would be easier to spot in the Winter months?
