Dujiangyan · Sichuan
Plan a private Dujiangyan tour: the 2,200-year-old irrigation system still working today, the fish-mouth, spillway and bottle-neck, plus the Nanqiao night riverside.
The short version
The place itself
Dujiangyan is not a monument; it is a machine, and it has been running without pause for about 2,270 years. Built between 256 and 251 BC by Li Bing, the Qin governor of Shu, and his son, it splits the Min River and sends part of it to irrigate the Chengdu plain, which is why that plain became the 'Land of Abundance' and why UNESCO listed the works, with nearby Mount Qingcheng, in 2000. It is the oldest surviving no-dam irrigation system in the world and still in use.
The whole thing comes down to three deceptively simple pieces. The fish-mouth divider splits the river by shape alone, taking the inner channel toward the plain and the outer one down the original course. The Flying Sand Weir spills the extra water off in flood and throws the silt back into the main river. And the Bottle-Neck, a gap cut through a mountain ridge, meters out the water at a fixed width — no gates, no dam, just the geometry of the land.
Around the three works, the visit is a walk through some of the oldest ground in Sichuan: the Leidui garden on the separated hill, with its bonsai and old trees; the Erwang Temple to Li Bing and his son; the wooden Anlan cable bridge across the river; the pavilion tower on Yulei hill; and the stub of the old Songmao trading road, once the route from Chengdu to Songpan. Cross the Nanqiao bridge and you are in Guanxian old town.
Come in the evening if you can. Dujiangyan keeps a slower pace than Chengdu — teahouses on the riverbank, cold beers and river fish along the Nanqiao 'night-beer' strip, and the lit-up bridge over the water. It is one of the most relaxed towns within an hour of the city, and the water is always moving under it.
Pins are plotted from real latitude and longitude on a 5° graticule. This is a schematic orientation diagram, not a political map — no boundaries are drawn.
The centrepiece of the system: a bank shaped like a fish's snout that sits in the middle of the Min River and divides it into the inner channel (for irrigation) and the outer one (for flood flow). What looks like a sandbar is a piece of hydraulic engineering 2,000 years ahead of its time, adjusting itself as the water rises and falls.
The unassuming spillway that keeps the plain dry: when the inner channel carries more than the Bottle-Neck can take, the excess pours over the weir and back to the Min River, and the same movement flings silt clear of the intake. In the past the weir was built of bamboo cages packed with stones; now it is concrete, but the principle is unchanged.
A narrow gap cut through the ridge that once joined the mountain to the riverbank, controlling the water flowing into the Chengdu plain. Cut by hand in the Qin dynasty, it is the metering gate of the whole system — the reason the plain gets water by design rather than by luck.
The Leidui — a small hill left standing on its own when the Bottle-Neck was cut — is now a garden of age-old trees and Sichuan-school bonsai. Beyond it, the Erwang Temple honours Li Bing and his son, and the cable lift rises to the Yulei tower for a view over the works, the bridges and the town.
The wooden Anlan cable bridge, slung across the Min River where the two channels separate, is one of the old images of Sichuan, and it sways underfoot as everyone walks it. Nearby, the last stretch of the Songmao trading road — the old route to Songpan, maybe opened as early as the Three Kingdoms — survives as a short walk.
Cross the decorated Nanqiao bridge over the river and you are in the rebuilt old town of Guanxian, with its Ming- and Qing-style streets. At night the riverside becomes the famous 'night-beer' strip: cold beer, river fish and a lit-up bridge over rushing water — Dujiangyan's most local evening.
Five regions, one journey: imperial north, panda country, the karst rivers of Guilin and the skyline of Shanghai, with Hangzhou's West Lake.
From US$2,580/per person
View tourFrom Chengdu, the easy way is the intercity train from Chengdu North or Chengdu West to Dujiangyan station — about 30 minutes and ¥15, with departures through the day (roughly 06:32–20:17 outward). Buses also run from Chadianzi and Ximen stations, from about ¥16, and a tourist shuttle leaves from outside the Wuhou Shrine with hourly departures in season. From the airport, there are a handful of daily coaches and the airport rail link into Chengdu, then the intercity train out.
Inside Dujiangyan, city buses connect the station, the old town and the scenic area — bus 4 links the fast-rail station with the Lidui park entrance at the Dujiangyan scenic area, and bus 101 runs between the town and Qingcheng Mountain. Taxis are cheap (¥5 flagfall). Most people visit Dujiangyan and Mount Qingcheng as one day: the scenic area in the morning, the old town and the night-beer strip in the evening, and Qingcheng the next day.

One day does Dujiangyan properly, and it pairs naturally with Mount Qingcheng for two. Spend the morning on the three works and the surrounding sights — in through the Lidui gate, along the weir and the bottle-neck, over the Anlan bridge to the Erwang Temple and up the Yulei tower — then the afternoon in the old town and the evening at the Nanqiao night-beer strip. The next day, take bus 101 or the intercity train to Qingcheng Mountain. People who try to do both in one day see all of it at a run and remember none of it.

The intercity train is the easiest: from Chengdu North or Chengdu West to Dujiangyan takes about 30 minutes for ¥15, with services through the day. There are also buses from Chadianzi and Ximen stations (from about ¥16) and a seasonal tourist shuttle from outside the Wuhou Shrine. Once you arrive, bus 4 goes to the scenic-area entrance and bus 101 to Qingcheng Mountain.
The ancient irrigation system is the whole point: the fish-mouth divider, the Flying Sand Weir and the Bottle-Neck, plus the Leidui garden, the Erwang Temple, the Anlan cable bridge and the Yulei tower. Add the Guanxian old town across the Nanqiao bridge, and in the evening the riverside night-beer strip. It is history you can watch working, with water still running through it after 2,270 years.
April to October. July and August are the classic months, when Dujiangyan and Qingcheng stay cool while the Chengdu basin swelters, and the summer night-beer festival fills the riverside. Early April brings the Water-Releasing Festival at Qingming, a re-enactment of the ancient dam-opening that is the town's biggest event. Winter is quiet and cheap, but cold and green-grey.
You can, but it is a rush, and most people regret it. The two are 10 km apart, and a combined ticket is ¥180. The sensible plan is Dujiangyan in one day — the works, the old town and the evening riverside — and Qingcheng Mountain the next. If you truly have one day, do the Dujiangyan works in the morning and Qingcheng's front mountain in the afternoon, and accept that you will be moving fast.
Yes — it is the rare historic site that is also a living piece of engineering, still doing its job after more than 2,270 years, and it is only 30 minutes from Chengdu by train. It suits anyone interested in how things work, and it is far less crowded and touristy than the big Chengdu sights. Pair it with Qingcheng Mountain and you have the best two-day escape from the city.
The Nanqiao 'night-beer' strip is the local ritual: cold beer, river fish, spiced rabbit and boiled peanuts by the water. In the old town and around, look for zhazha noodles, jisi doufunao (silken tofu with chicken), spring rolls at the Wuqui bridge, and the 'four treasures of Qingcheng' — Daoist rice wine, tribute tea, pickles and ginkgo-and-chicken soup. It is Sichuan cooking at its most everyday.
