The route continues westward through the village of Fyfield, across Overton Hill where there is a parking area at the start of the Ridgeway National Trail and through the village of West Kennet. On leaving West Kennet there are some parking lay-bys where visitors can walk a short distance from the road to the Neolithic West Kennet Long Barrow, which forms part of the Avebury World Heritage Site. One mile further along the A4 is Silbury Hill, which is also part of the Avebury World Heritage Site. A purpose built car park is located beyond the hill on the right travelling westward.
