Directions from Nowich
A14 towards the M11, M11 south to the M25, M25 clockwise to Dartford Tunnel/Bridge, As you approach the tolls stay as left as possible, when you exit the toll gate take the 1st junction off , it's like 100 yrds out of the toll.
Then at the roundabout go right, over the top of the M25 on the A206 next roundabout straight over 2nd exit I think?.still on the A206, next roundabout 1st exit /straight over, next roundabout right 2nd exit one thinks?...at the top bear left follow through the gate and keep an eye on the left, about 500 yrd you will see the fields turn in and park....turn off engine, apply handbrake, get out lock door walk over to the fields and watch...
Hope this helps
