The last spring , my friend Sam and I decided to visit Kungur Ice Cave. When we arrived, it was freezing cold, and we saw snow.
We saw 20 grottos , 60 lakes and other many interesting. We were wonderful nature. We went in labyrinths,  later saw the "Titanic" is famous underground lake and is one of the most interesting grottos. I was shocked very crystal clear water in this underground lake .
Then excursion finished.
