There is a large and deep cave, and there is a river below. When a small boat is driving in the river, it sometimes has to lower its head, otherwise it will hit the stone above. The lighting is beautiful. I think it was the light that made this hole perfect, especially when it came out, the sky above the hole suddenly became clear.
The cave has a round boulder, in the middle of the flow, for the spring water, issued a loud noise, rock wall echo, like the sound of dragon mill, so called dragon rock.
These are worthy of everyone to pick and choose, and see what you really want, come with friends!
Natural cave, good environment, worth visiting.
It’s a free attraction, just a former arsenal
