First view of Silbury Hill from the Ridgeway, just North of the Wansdyke, descending into the Kennett Valley from the South. The very first sign that you have entered the Avebury landscape!
Silbury follows the opposite ridge, Harestone Down, from the Ridgeway in exactly the same way as Julian Cope described happening further to the North, where it skims the top of Waden Hill on the first stretch of the official Ridgeway.
