In the mineshaft the average annual temperature in the bottom is 7°C, it is quite wet and when it is raining outside, water flows through the mineshaft and down its walls.
We recommend warm "outdoor" clothing, including warm socks and boots. Visitors must reckon with the possible contamination of their clothing.
Visitors before entering the mine are provided free of charge with:
- Safety helmets with lamps.
- Raincoats and gloves.
- Boots, if you do not have your own ones.
In the vicinity of the mineshaft Johannes coverage of mobile operators is very poor. Get all necessary information and tour itinerary in advance.
