Not like that now , nice walk into local village couple of pubs.Stayed there a few years ago for a Christmas rally. First RV to park up sunk into the grass. As the site was empty we parked up on the roads. Reasonable site with warm clean facilities. It was a tight turn in and the exit is a narrow one way road used by commuters to park their cars.
Definitely need a car. There is a bus to Hitchin 15 minute walk away or train station 5 minutes walk.
