The West Kennet Avenue is a double row of standing stones that once connected Avebury to The Sanctuary circle on Overton Hill, nearly 2.5 kilometres to the south-east. Walking the avenue today — past the restored stretches of stone pairs flanking a farm track — gives a sense of what the complete processional route must have been like.
Only a section near Avebury has been fully restored; further south the avenue becomes fragmentary and then disappears entirely. The walk is a good way to reach Silbury Hill and West Kennet Long Barrow, passing through countryside that has changed relatively little since the Neolithic. The avenue is managed by the National Trust and freely accessible.
