This is the Tianmen Mountain, often called "Heaven's Gate", located a few miles from Zhangjiajie City in China.
Many people from all over the world trek out to gaze upon this natural beauty.
You will definitely be huffing and puffing after the 7 mile hike ending with 999 steps straight up.
If the hike seems like too much, you could opt out and ride the world's longest cable ride, but you still have to climb the steps when you get off.
There is also a 500 year old Temple at the very top that you can explore.
This is such a cool place to visit!
