Getting to the Brooklands site is quite straightforward, but getting to the correct entrance is not so obvious.
From the M25 junction 10 take the A3 towards London.
As you join the A3 you will need to stay in the left hand lane to take the first turning left. As you exit the A3 take the first exit on the left and head for Weybridge. Follow the brown tourist signs for Brooklands Museum. After a couple of miles you will come to a roundabout, take the second exit and continue to follow the brown tourist signs for Brooklands Museum.
Once you pass the petrol station (with a cashpoint..) you will come to this roundabout ;
At this point,
stop following the brown signs and take the second exit to continue up the hill.
You will then need to take the first turning on the left ,marked "Gallagher", it will look like this ;
The small sign on the right hand side reads Campbell entrance.
Follow the small road down until you get to a small junction , take the left hand road which will bring you to the entrance gate.
If you miss the "gallagher" turn off and get to here ;
.....then you've gone too far and need to turn around to take the next right ;
Hope this helps.
If you get lost dont worry, following the brown signs will get you there - it just means you will end up parked the wrong side of the fence.
