Every show cave, mine or subterranea on this site has a short list
of hard facts called Useful Information.
With a contemporary browser it will be displayed like this text, with
smaller font and darkgreen letters on white background.
In the Useful Information block you find information in a very brief form, which makes some explanation necessary.
It is very difficult to write dates, fees and hours in a well readable manner, so we always tried to find a sort of "international" way of writing it, which should be understood by anybody. But if you do not understand it, here is the explanation:
Show caves are generally not very good concerning accessibility. Thats easy to understand, natural caves have low ceilings, uneven floor, descents, and narrow passages. To develop such a cave in an highly accessible way generally collides with nature protection, as it would require massive destructions in the cave. Nevertheless we find it important to give an idea which level of ability is required to visit a cave. Unfortunately this kind of information is published rarely and or own knowledge is rather limited.
