I wonder which countries are listed as countries with many caves for tourism and exploring? I really love caves and in my area, there are not so many. I travel the world often so I will be glad to read some good advices.
When we travelled accross the Europe, we have visited two really awesome caves in a small country Slovenia (between Austria and Croatia). The first one is Postojnska jama which I rhink is the deepest or biggest one in whole Europe and the second was the Skocjan Caves, where they have a bride like in Lords of the Rings (Bridge of Khazad-dûm) and it's positioned really hig.
