As we were driving to cave, we saw a big elephant walk across the street. When came to the cave found. Nobody else, which is something that is very surprising. In the cave, we see the light a little and suddenly the children shouted loudly,we ran to the cave, Inside the cave there are squirrels as big as a dog in it. it is very cute and not dangerous. when in to the cave we see drawing on cave walls. and beautiful stalactites it looks like a diamond.I went into a deep the dark and less air But in the end, we were able to come out safely as well as 4 km distance, and travel in this time, I and my family are very happy.
