Nurburgring - walking to the karussel from the inside of the track?

[kevin993]

I know that one can walk along the outside of the track from Brünnchen and end up with a good view of the Karussel with the cars coming into the corner and exiting around you. Is there a way to walk from the inside of the track and get to the other side of the corner to get photos? It can't be easy or else there would be plenty of notes on the web about how to get there, but there are enough photos out there to show that the trip is worthwhile. Thanks.
