Leave the M20 at junction 7 and follow the A249 to Sittingbourne. Alternatively, leave the M2 at junction 5 and join the same road (A249). Take the exit (it's the second exit after the M2 junction) from the A249 that is signposted Sittingbourne Industry and turn right at the roundabout at the end of the slip road, following the road towards the Sittingbourne Industrial area. Go straight over two roundabouts and then turn right at the next roundabout. Then proceed straight over two more roundabouts and then turn left at the T-junction. Follow the road and take the second turning on the left and then the first left off of this road into Symmonds Drive. The track is at the bottom of this road.
This is not an easy track to find, so leave yourself plenty of time, take a map and be ready to ask for directions! It may also be beneficial to check the web site for the circuit in order to get a more detailed map!
