It is the most strategic place to stand at viewing platform to view the entire big window of the cave.

the viewing platform is accessible using staircase.  From the picture above, can you imaging how big is the cave?

Standing at the viewing platform, we can see the balcony;  same vice versa.  I wonder long time ago, the cavemen might have to shout to each other if they stood at different corner in the cave.

There is a mysterious red bench not far from the viewing platform.

And…  there was a piece of red cloth on the bench.  …  Does it looked scary?

We thought we are the only human in the cave because it was already 5 pm and the rain had just stopped.  But suddenly another group of people came.

When we were getting out of the cave, there was another group of a family who wanted to get into the cave.  We met them after we walked down the staircase and before we got into our car.  They asked me how does the cave look like, and how difficult to get into there.  I told them the cave is big and wide inside, and they have to get through 2 level of small and narrow staircases, and I told them it was getting dark.  They did not go into the cave.
