Exit at junction 28 of the M25 onto the A12 signposted Chelmsford.
Exit the A12 at junction 18 onto the A414 signposted Danbury.
Keep on the A414 (straight through Danbury) for 3.8 miles to the Oak Corner roundabout and go straight across onto the B1010 signposted Burnham.
After 2.3 miles you will get to a sharp left bend with a vineyards on your left and a junction on your right.
Turn right here into Pump Lane.
Take the third left into Howe Green Road.
After 0.5 miles (just into national speed limit) you will see a pair of gates on your right,with a MAD squirrel sign outside.
Turn in and the toilet roll will be on your left!
Hope the helps.
