Nothing spectacular, but nice natural single track with a couple of surprises.
I ride here when i can. It's all natural but there is a GPX file available from Get Mountainbikings Website. It's all fairly easy riding with lots of scope to explore. Someone has built some berms and jumps and these are tucked away in the woods, i rode them twice just to remember where they were.
They manage a nice 6 miles, but i guess you could do a lot more if exploring.
Parking is opposite the site, and you can grab some food or a coffee in the garden centre.
