Huanglong is a high valley in the Minshan mountains of northern Sichuan where lime-rich water has built a staircase of thousands of coloured travertine pools, shoals and falls, winding down the valley floor like the scales of a yellow dragon. It has been a UNESCO World Heritage site since 1992, together with the neighbouring Munigou valley, and a UNESCO biosphere reserve since 2000.

Key facts
Overview
The main valley of Huanglong is a narrow gully a few kilometres long, running up from about 3,100 metres to the Five-Colour Pool at around 3,550 metres beneath the snow peak of Xuebaoding, the highest summit of the Minshan. Its floor is almost entirely travertine: a pale yellow ribbon of calcite terraces, rimmed pools and sheets of shallow flowing water, set in forest of spruce and fir.
The protected area also takes in the Munigou valley to the west, with its own travertine falls and lakes. Huanglong lies in Songpan county in the Ngawa (Aba) Tibetan and Qiang Autonomous Prefecture, about 100 km south of Jiuzhaigou, and the two World Heritage sites are usually seen together.
How the landscape formed
Huanglong is one of the finest examples of active travertine deposition in the world. Groundwater draining through limestone beneath the Minshan is charged with carbon dioxide and dissolved calcium carbonate. Where it emerges at springs and flows over the valley floor, it loses carbon dioxide and deposits calcite, especially at edges where the water speeds up or splashes. Over thousands of years this has built rimstone dams that hold back terraced pools, broad sloping shoals and cascades. Algae, bacteria and mosses help trap the calcite and tint the pools yellow, green and blue. The valley was shaped by glaciers, and the high peaks around it still carry small glaciers and permanent snow.
Highlights
Five-Colour Pool
五彩池
The largest group of terraced pools, at the head of the valley near the old temple, in shades of blue, green and yellow below Xuebaoding.
Golden Sand Floor
金沙铺地
A long, broad sheet of travertine over which a thin film of water flows, giving the valley its dragon-scale look.
Contending Beauty Pools
争艳池
A dense cluster of rimmed pools of different colours in the middle of the valley.
Body-Washing Cave

Munigou valley
牟尼沟
The second part of the World Heritage site, west of Songpan, with the Zhaga waterfall and the travertine lakes of the Erdaohai valley.
Plants and wildlife
The reserve spans nearly 4,000 metres of altitude, from mixed forest in the valleys through subalpine conifer woods and alpine meadow to rock, snow and glacier. It lies within the wider habitat of the giant panda in the Minshan and shares much of its flora and fauna with Jiuzhaigou.
Plants

Culture and legend
The valley takes its name from the Yellow Dragon Perfected One (黄龙真人), a Daoist figure who, in legend, helped Yu the Great tame the floods and later cultivated immortality here. A temple to him has stood at the head of the valley since at least the Ming dynasty. Huanglong is also sacred to the Tibetan and Qiang communities of the Songpan area, and a temple fair in the sixth lunar month draws Han, Tibetan, Qiang and Hui people to the valley.
Huanglong Ancient Temple
黄龙古寺
The Daoist temple beside the Five-Colour Pool, traditionally dated to the Ming dynasty.
Huanglong temple fair
黄龙庙会
A summer gathering of pilgrims, traders and singers from the surrounding peoples, held around the fifteenth day of the sixth lunar month.
Songpan old town
松潘古城
The walled garrison town on the upper Min River, long a trading post between Sichuan and the Tibetan grasslands.
History
Ming dynasty (1368–1644)
Huanglong Temple built
The temple at the head of the valley made Huanglong a pilgrimage site for Daoists and local peoples.
1982
National scenic area
Listed with Jiuzhaigou in the first group of national key scenic areas of China.
1992
UNESCO World Heritage
Inscribed as a natural site together with Munigou, the same year as Jiuzhaigou.
2000
UNESCO biosphere reserve
Added to the World Network of Biosphere Reserves.
2008 and 2017
Earthquakes in the region
The Wenchuan and Jiuzhaigou earthquakes affected access roads; the travertine landscape itself remains active and changeable.
Through the seasons
Spring
Cold and often snowy until May; the pools can be low before snowmelt and the rains fill them.
Summer
The pools are fullest and most colourful from June to September, with afternoon showers and cool air.
Autumn
Clear days and golden larch and birch in late September and October; nights are near freezing.
Winter
Snow and ice cover the valley and much of the water freezes; access can be limited in bad weather.
Routes and ways in
The valley boardwalk
A raised wooden walkway climbs the length of the valley from the lower entrance to the Five-Colour Pool and the temple, with a separate descending path; the full round takes most of a day at a slow, altitude-conscious pace.
Cable car and descent on foot
A cable car lifts visitors to the upper slopes, from where a level path leads to the upper pools; many then walk down the whole valley, which is easier at this altitude than climbing it.
Munigou
A separate, quieter area near Songpan with walking paths to the Zhaga waterfall and the lakes of Erdaohai.
Practical notes
- The upper valley lies at about 3,500 metres: walk slowly, drink water and descend if headache or breathlessness worsens.
- The road from Songpan crosses a pass of more than 4,000 metres; travellers coming straight from the Sichuan Basin can feel the altitude on arrival.
- Walking on the travertine and entering the pools are forbidden; the deposits are fragile and easily broken.
- Jiuzhai Huanglong Airport and the Huanglong Jiuzhai station on the Chengdu high-speed line serve both World Heritage sites; Songpan and Chuanzhusi have most accommodation.
