A greenhouse on a hill
A greenhouse located on the hill ... you can walk there, especially if you don't feel like paying for a guided tour of the mining areas. This place was created to try to curb problems with tourists, who want to visit the mines without paying for a proper tour, and contribute to the black market economy. Be careful if you plan on doing this: the miners are not qualified guides, and things can get dangerous.
