Yep.
When I were a lad the only section there was public access to was a small area to the south of the road (by the Water Tower). It's sand and gravel as far as I can remember, similar to Cannock, but not particularly extensive.
As an aside, I believe the first major motorway pile-up in heavy fog (Nov 5th 196?) occured under that pedestrian bridge giving access to Trentham Gardens, and I was there!
