From the A41 roundabout just past the overhead M1, continue along the B462 towards Bushey. After about half-a-mile, continue across a roundabout and after another 150 yards, turn left at a second large roundabout and into a tree-lined avenue. Turn right at the top of The Avenue and after 200 yards cross a mini-roundabout. Then take the second right into Rudolph Road. The Museum is the large building on the left after the long row of houses. Drive into the car park entrance by the side of the Museum. Rudolph Road is one-way.
