Mount Lang

崀山 (Làng Shān)

Red sandstone domes, slot canyons and the Fuyi river on the Hunan–Guangxi border

Mount Lang (Langshan) in Xinning county, south-western Hunan, is a landscape of red sandstone and conglomerate cliffs, domes and narrow slot canyons along the Fuyi river. It is one of the six components of the China Danxia World Heritage site, inscribed in 2010, and includes the Bajiao Zhai massif on the border with Guangxi.

Overview

Langshan is one of the most varied Danxia landscapes in China. Within a relatively small area it shows almost every form that red sandstone takes as it erodes: sheer walls, isolated peaks, flat-topped mesas, rounded domes, arches, caves and narrow alleys between cliffs. The clear Fuyi river winds between them, and farmland and villages fill the valleys.

The name uses a rare character, 崀 (làng), which appears almost only in this place-name. Local tradition links it to the Shun emperor, who is said to have passed through on his southern tour and praised the landscape; the region has long been farmed and settled, and Langshan is less a wilderness than a lived-in red rock country.

How the landscape formed

The rocks are red sandstones and conglomerates deposited in an inland basin during the Cretaceous, when rivers and alluvial fans filled a subsiding trough with iron-stained sediment. Uplift and jointing then exposed the beds to erosion. Water working along vertical joints cut deep, narrow clefts such as the One-Line Sky; wider valleys isolated blocks into peaks and ridges; and in the south, around Bajiao Zhai, closely spaced domes formed a mature landscape of rounded summits. Langshan's range of forms — from youthful clefts to old-age domes — was a key reason for its inclusion in the China Danxia serial site.

Highlights

  • One-Line Sky Alley

    天一巷 (Tiānyī Xiàng)

    A slot between cliffs more than two hundred metres long and in places barely wide enough to pass sideways, with a thin strip of sky overhead.

  • Bajiao Zhai

    八角寨 (Bājiǎo Zhài)

    The highest massif of the area, with a summit view over a sea of red domes likened to whales breaching the waves (鲸鱼闹海).

  • Chilli Pepper Peak

    辣椒峰 (Làjiāo Fēng)

    A tall, tapering tower of red rock that narrows towards its base, a well-known climbing objective.

  • Fuyi River

    夫夷江 (Fūyí Jiāng)

    The river that meanders through the area between cliffs and bamboo groves, travelled on rafts.

  • Natural Bridge

    天生桥 (Tiānshēng Qiáo)

    A great arch of sandstone spanning a valley, one of the largest Danxia arches in China.

  • Camel Peak

    骆驼峰 (Luòtuo Fēng)

    A long humped ridge of red rock, among the most photographed formations.

Plants and wildlife

The humid subtropical climate covers the red rock in evergreen broadleaf forest, and the shaded clefts and cliffs provide microhabitats for ferns, mosses and plants adapted to thin soils. The contrast of green forest and red walls is characteristic of the Danxia landscapes of southern China.

Plants

  • Ziyuan fir

    资源冷杉 (Zīyuán lěngshān)

    Abies ziyuanensis, a rare fir of the mountains on the Hunan–Guangxi border.

  • Moso bamboo

    毛竹 (máozhú)

    Covers the valley slopes along the Fuyi river.

Wildlife

  • Silver pheasant

    白鹇 (báixián)

    A pheasant of the forested slopes.

Culture and legend

The area has been farmed by Han and Yao communities for centuries. Old villages with grey-brick houses stand in the valleys, and Xinning county is known for the navel oranges grown on its slopes. Tradition says the Shun emperor named the place, and the phrase “Langshan is beautiful” (崀山美) is attributed to him.

  • Xinning county

    新宁 (Xīnníng)

    The county in Shaoyang prefecture that administers Langshan.

  • Navel oranges

    脐橙 (qíchéng)

    The main orchard crop of the valleys around Langshan.

Through the seasons

  • Spring

    Wet and misty; the river runs high and the forests are fresh green.

  • Summer

    Hot and humid with thunderstorms; rafting on the Fuyi river is at its most popular.

  • Autumn

    Clear, dry weather — the best season for views from Bajiao Zhai and for walking the clefts.

  • Winter

    Cool and quiet, occasionally frosty; the red rock stands out against bare fields.

Routes and ways in

  1. One-Line Sky and the Natural Bridge

    Walks through the narrow alley and valley paths in the central area, a few hours on foot.

  2. Bajiao Zhai summit

    A steep stepped climb to the summit ridge viewpoints over the dome field, usually a half-day or more.

  3. Fuyi river rafting

    Bamboo rafts drift down the river past Chilli Pepper Peak and other formations.

Practical notes

  • The clefts are narrow, dim and sometimes wet underfoot; they are not for people who dislike tight spaces.
  • Paths to Bajiao Zhai are steep and exposed in places, with railings; avoid them in heavy rain.
  • Langshan lies far from the provincial capital: the county seat of Xinning and the city of Shaoyang are the local bases, and Guilin in neighbouring Guangxi is also relatively close.
