Yes, it does! Enjoy it!

Unlikely, it would take you about 2 hours just go up and down by a cable car.

The maps are confusing and even the Lonely Planet's description did not give us a clear idea of the layout. Tianzi Shan refers to the main area of high ground within the park. The South and West edges of this area are precipitous with the Karst towers that make the place famous.  The Golden Whip Stream and the Suoxi river run below the southern cliffs. The climb up to the top of the precipices varies between 300 and 500m. Road access was originally from the the North which was a long drive from Zhangjiajie City. From the Wulingyuan entrance free (purple) buses run to the Bailong Elevator and the Tianzi Shan Cable car. From the top of the elevator more free purple buses run to The No1 Highest natural bridge. From the top of Tianzi Shan Cable car purple buses run to Tianzi Shan scenic area. Both the locations served by the purple buses are very spectacular but horrendously crowded on weekends. There is even a MacDonalds in the Tianzi Shan scenic area. There are smaller brown shuttle buses that link these two main locations. Most of the punters can't or won't walk. So if you do walk you do not have to go far to get away from the crowds. We walked from from Tianzi Shan Scenic down to a bus stop on the shuttle route to the elevator. Much of the time we were quite alone. Delightful!

Generally people would fly to Zhangjiajie Airport (DYG). Wulingyuan Scenic Zone has four parts: Zhangjiajie National Forest Park, Suoxiyu, Tianzi Mountain, Yangjiajie. You buy one pass and you can visit all four parts. You can re-enter multiple times in four days. Most people stay near Biaozhimen/Landmark Gate. It's about 30km from the airport, and there are many hotels and restaurants. I would recommend you to avoid peak season such as summer holiday and public holidays. Most people need two to three days for Wulingyuan, and another day for Tianmen Mountain, which is about 5 km from the airport. Hope this helps and enjoy your trip.

Hello! I`ve never been in the Yellow Mountains, but you must go to the Tianzi Mountain. Its very beautiful and you can walk as far as you want. Anyone can do it, including the 6 years old kid. My tip for hotel is the Pullman Hotel, the only International Hotel in town (Zhangjiajie). Good luck!!!
