Coming from Aachen/Koln the route to the quarry is as following:
Take exit 86 on the highway 1 towards highway 45 to Giessen-Siegen-Frankfurt
Take exit 12 on the highway 45 to Hagen Sud
At the end of the exit turn left ; you're on the Herbecker road
At the end of this road on the T-crossing, turn left to the B7 on the Hohenlimburger Strasse
After a few kilometers you pass the large quarry on your left hand and you see the entry to the quarry.
