OK, this route may be good and it’s also interesting:
Start from around Shrewton then head up towards the Bustard Inn to use the perimeter track until Larkhill. Through houses to reach The Cursus that leads to Stonehenge. Cross over both the A344 and A303 to Normanton Down and its many barrows.
Cross the A360 to go through Druid’s Lodge and drop down into the valley at Berwick St. James. There is a brilliant farm shop and cafe with superb bread pudding. Take byway that runs behind the cafe but this will be muddy. Turn R at byway X-roads to head up to A303. Cross over by Yarnbury hill fort.
You can now either head to Chitterne or cross Plain heading for Army village. Head E to go through Orcheston, enjoying a bridleway descent.
If you want some grid references, give me a shout.
