Zhangjiajie Tianmen Mountain National Forest Park is worth visiting. 7.5 kilometers of ropeway from the city to the top of the mountain is really relaxing and pleasant. Ninety-nine hundred and ninety-nine steps go straight up to the entrance of the Tianmen Gate, and strive to go straight up to that magnificent spectacle. Walking along the glass trestle road in person, it was a scream of trepidation. The world's longest mountain escalator, that long foot has more than 1000 meters straight to the top of the mountain. We all screamed at the 99 sharp turns that took us around the hill in an eco-friendly car. It's thrilling and unforgettable.
