It is chalky like the rest of the Chiltern hills, apparently formed from fish bones. The ice age stopped to form the 'cliff' of the clappers.
The woods are a great place to explore, but are steep in places.
There are a few benches dotted about, and a big grassed area, that you can sit on for a picnic if you take a blanket. There is a footpath to the woods that you can wheel a buggy, and then explore the rest of the place on foot. There are no toilets at the site.
NT says:
"Reputedly haunted, Sharpenhoe Clappers is a classic chalk escarpment and part of the Chilterns Area of Outstanding Natural Beauty. It is crowned with traces of an Iron Age hill-fort and an impressive beech wood."
There are a few walks in the area, here is one that I have found, that has lots of useful information:
Walk like the Clappers
