A fantastic e-bike and "underground" group experience 

An offer for 20 to 80 people

Bookable from May to October

Experience our world underground and then it's time: Pedal through beautiful Heidiland to find the treasure.

After a short explanation of the rules of the game, the first problem has to be solved: cracking the numerical code for the bike lock. The next hurdle is the treasure map. Deciphering it requires team spirit, ideas, inventiveness and creativity. Then it's off! Off you go on the comfortable country bikes!

Our support staff at the mine and the OUTIVITY guides team up to give you a great day out.

From exciting blasting demonstrations, food and information to an exciting e-bike treasure hunt. The day has something for everyone and the "pedalling" is rewarded with beautiful views.
