If you approach the site anticlockwise on m25 exit junction 8 and take the third exit then left signpost Mertsham onto Gatton lane?. Travel a couple of miles then beneath m25 and turn left onto A23. Take 2nd right into Shephards Hill (curry house on corner) Up the hill and left into Dean lane site 100yds on right. This will save you 20 mins and several u necessary miles. Great site . A lot of workers also using site but who can blame them with the extortionate accommodation costs in London. Very clean facilities. Friendly wardens.
