This is my local club site and I really quite like it.
It's quite a challenging site which keeps you on your toes as it's quite compact amongst trees with a bit of everything within it.
I started going down there with my Mrs when I first started offroading in our SJ410 and met our good friends James and Claire via this site in it's first incarnation and joined 4x4er together.
Now we've progressed to my very modified Jimny and are regulars down there.
Decent Off Road sites are scarce in Essex with this and one other really available. This is my favourite though!
