From a previous version of the article:
"Definitely don't miss the FREE tour to the mine. Go to the tourist information (early morning, 9am! or the day before) and reservate your seat for the tour. It is totally free and really awesome. The tour starts at about 2pm and lasts 2 hours. You need to go to this freaky town outside (I forgot the name, sorry). You can try to hitchhike, but there is not a lot of traffic! I recommend the collectivo. But you definitely can hitchhike back as you meet some tourists with rental car" (User:Bernhard).
