Tianmen Mountain (天门山, Tiānmén Shān) is visible from anywhere in Zhangjiajie City. Its most distinctive feature is Tianmen Dong (天门洞), a natural hole, 113m tall, through the mountainside. There's a temple at the summit, a chairlift ride and a circular walking route that includes two glass-bottomed sections, in case you weren't already reeling from the awesome surrounding views.
Tianmen is accessed by two cable cars. Line A is the 7.5km-long Tianmen Mountain Cableway (天门山索道, Tiānmén Shān Suǒdào), starting in central Zhangjiajie and whisking you in two stages close to the summit. If tickets are sold out (or lines too long) for this route, take the Line C Tianmen Cave Expressway Cableway – a shuttle bus from the Line A station takes you here and is included in the ticket price. This cable-car's upper station is a 500m walk from the steps leading up to Tianmen Dong. Pay extra to ride a series of escalators rising nearly 900m inside the mountain to reach the summit.
It's easy to spend half a day on Tianmen – if you visit in the afternoon, stay for the light show that plays around Tianmen Dong after sunset. Time your descent right and you can also catch the Fairy Fox Show next to the lower station of the Tianamen Cave Expressway Cable Car.
