Avatar Hallelujah Mountain, Sandstone pillar in Zhangjiajie National Forest Park, China.

Avatar Hallelujah Mountain is a quartz-sandstone pillar in Zhangjiajie National Forest Park, rising about 1,080 metres from the valley floor. Its pale tan and grey rock is split by horizontal bands and deep vertical cracks, with vegetation growing on the flat summit and clinging to ledges. The pillar was shaped by physical erosion, mainly from expanding ice in winter and plants rooted in the stone.

Originally called Southern Sky Column, the formation received its current name in 2010 following the release of James Cameron's Avatar film. The renaming transformed the site into a major tourist destination and brought worldwide attention to the region.

The pillar was long known as Qiankun Zhu, "Column of the Universe", and also as Nantian Yizhu, "Southern Sky Column". On 25 January 2010 the Hunan Provincial People's Congress renamed it Avatar Hallelujah Mountain, citing the film's social message. The park's quartz-sandstone pillars appear in many ancient Chinese paintings.

Visitors can reach the viewing areas by taking the Bailong Elevator or by walking on the established trails that connect throughout the park. Visiting on clear days offers the best views, as mist and clouds often obscure the rock formations.

The pillar was long known as Qiankun Zhu, "Column of the Universe", or Nantian Yizhu, "Southern Sky Column", before the Hunan Provincial People's Congress renamed it on 25 January 2010. The park's own quartz-sandstone pillars, not floating islands, were the model; the film's designers cited Guilin, Huangshan and Zhangjiajie as inspiration.
