Long time since I saw the film. All I can remember from the closing scene is all the actors accompanying the survivors they played in the film placing pebbles on Schindlers grave.
Details of where he is buried can be found here I assume if the road exists it is here.
I know Speilberg could not get permission to film in the camp so they created a replica outside the gates. When you see them all walking into the camp they are in fact walking the opposite way from what they would have done.
