Hi Anna

In answer to your question about what you can see of the Durrington Walls Henge, I have ftp'd some pictures taken from the old road which runs through the site. Unfortunately there are no information boards on any part of the henge, so unless you have a map of the area, you wouldn't even know you were driving through the henge. There is however a picnic area with parking sign posted off the A345 Durrington to Amesbury road. This also serves as the parking for Woodhenge.

Might I suggest you read up on some posts on this site to familiarize yourself with the layout of the Stonehenge area, before you visit.

Check out the maps at http://www.themodernantiquarian.com/img_fullsize/72943.jpg and
http://www.themodernantiquarian.com/img_fullsize/72944.jpg for an overall picture.

You can pull off the road at various points and park up if you slow down enough before you reach them.

Travelling East down the A303, you can turn off the droveway and walk down to Bush barrow and Normanton Down.

Again on the A303, you can go around the Long barrow roundabout, park in the lay-by and walk up to the Winterbourne Stoke group.

Travel back up the A303 past Stonehenge and slow down when you get past Stonehenge Bottom, pull off to the right by the cottages and park. You can walk up to the New and Old King Barrows from here, as well as, seeing Stonehenge, the Cursus and possibly the Avenue.

Parking in the Stonehenge car park is free and you could always walk to sites listed above.

If you do visit Silbury hill and WKLB, take the time to check out Swallowhead Spring while your there. I'm Sure your'll love it

Good fortune on the road Anna
