The Walk of Faith is amazing, if you are brave enough to do it! Tianmen Mountain Park was one of the highlights of our trip to China. It is the main tourist attraction (I think) of Hunan Province, and is located very near Zhangjiajie city - so close that you can take a ride on the world's longest cableway from the city to the summit of the mountain. There is lots to do on the mountain: Tianmen Cave is otherworldly and really does look like a doorway into another universe, and there are interesting temples and astounding views all over. You'll need a full day to explore. Guilin, a very picturesque and tourist-friendly city, is about 4 hours drive away. Loads to do there.
