Discover the mine with a guide or by yourself with a torch and a helmet on your head.

There is a lake inside the mine and several places, shafts and passageways. Some of the passageways are unlighted so it might probably become a bit adventurous to go in. But you need not to be afraid to get lost.

Take with you warm clothing and waterproof shoes because it is rather cold and wet inside (you can also lend jackets and rubberboots ).
