Try viewing Silbury from a distance (its eases the mind and soothes the soul that way!).
I've always felt that there are at least three very different aspects to Silbury - one ON the Hill, one up-close and one from a distance. One of the most distant views of Silbury is from Winterbourne Bassett - go south 200-300 metres down the farm road from the Bassett Circle and look towards the southerely tree line - you have to search a while to see it but it's worthwhile.
Silbury's also visible from most of the approach roads into Avebury but not at all times of the year. It's visible from just one point in/on the Avebury Circle - from the north-east bank of the Avebury Ridge (though it's also visible from some of the houses within Avebury).
Silbury spotting is more than just satisfying it's also a lot of fun (especially if you have kids) and will give you and them a personal and very special memory of this most amazing of mounds.
If anyone knows of a more distant view of Silbury than the one from Witerbourne Bassett I'd really like to know.
