Dont expect to see a castle here unless you understand that in the 6th Century BC a castle was a pair of concentric circular raised mounds or earthworks with a 'moat' in between. This is the perfect place for a picnic on a summer day, especially in the lovely field next to the car park.
The road up to the hillfort from Wroughton is steep and winding for the last half a mile and from it you might look out for yellowhammers and other birds of all types, especially finches in the trees and hedges at the side.
On the flat road before the steep part look for deer in the fields either side and also crop circles which mysteriously appear in these parts overnight !
Once at the top you can park up, picnic, take a walk over to the castle itself and admire the views all around. On the way to the castle take a look to the left for a fine vista over Barbury Castle Estate and RaceCourse. On a fine day it's really spectacular up here and the myriad of kites give it colour.
There is a cafe in the farm on the roadside at the top and also public toilets in the car park just before you enter the field with the path to the castle. At the castle itself you can walk all the way round one of the mounds which takes about 20 minutes at a slowish pace. In summer you will see a huge number of wild flower species which in turn attracts one of England's largest number of butterflies and moths species in one place.
It's good to just lie down on the grass in the sun and enjoy! Dont go here when there's any wind forecast though and watch for a very muddy field entrance after rain, especially in winter and autumn.
