It depends what you want.
I start quite often at Seven Springs car park and head into the chase from there. A lot of the trails are not marked but quite often it is just about looking for a trail into the woods etc.
You won’t find berms or big drops but you do a good long ride with climbs and descents to have some fun with.
There is also the old quarry that has a few drops into it. Nothing big but still something to play around in.
If you start from the trail centre you ride the Dog to the point where you cross the road and instead of going throughout the caravan site head off to the left and this gives you a big area to explore. On your way back you can return to the dog and finish with the Werewolf drop and the Rollers before going the cafe.
Have a look on google maps. You can’t see the trails but it will give you an idea of the space.
Hope that helps
