The national geological park is a resort of both high value of geologic and scientific research, aesthetic appreciation and landscape. Another attractive and mysterious thing is that the color of rocks here can change with weather and temperature. In summer with hot sun, its color turns into fiery red. During cloudy days, it would be maroon and purple. However in heavy rainy day, it is black.
The park will certainly give you a brand new tourism experience.
