In the summer of 2008 I visited this mine legal since I had never visit one before at that time. The tour starts going down an elevator very deep u can feel the temperature changing. The guide itself made the whole tour even more exciting since he like to scare the tourist. He did this not one time but really the whole tour with putting sounds very loud or starting machines without notifying. For me it was a good experience I stayed a bit behind the group to look around a bit and take some pictures. The pictures were taken in 2008 at the start of me taking pictures. I used a sony A200 to take these pictures. Normally it was even forbidden to take pictures but because a week before some official ministers visited the place and took pictures I was aloud to take some. I had no tripod with me so I had to boost the iso really high.
