Dujiangyan: A Living Irrigation System near Chengdu

Dujiangyan shows how a river can feed farmland without a dam, and it has done so for more than 2,200 years.^[1] Gardens, temples and a famous suspension bridge fill the spaces between the waterworks.^[2] Plan half a day for the waterworks, plus the trip from Chengdu. Qingcheng Mountain, the other half of the World Heritage listing, is better planned as its own outing.

Tickets and your entrance come first

In April 2026 standard admission was RMB 80 per person, and the site opens 08:00 to 17:00. Visitors aged 65 and over enter free.^[2] Book ahead and check the last admission time for your date. Rail, the final transfer and any optional transport or guiding cost extra.

For the 2026 October holiday, Chengdu announced reservations by time slot and by entrance, with one-way circulation in key areas at peak times.^[3] When you book, note the entrance name and its map pin as well as the time. Send that exact pin to your driver and plan your return from the exit you will use.

From Chengdu: compare the actual stations

Take the Chengdu-Dujiangyan fast railway and search 12306 for your date using the Chinese station names. Lidui Gongyuan (离堆公园) and Dujiangyan (都江堰) are different stations. Chengdu’s 2019 access guide sends you on foot from Lidui Gongyuan to the scenic area, but by bus 4 from Dujiangyan station.^[4] Match the station to your booked entrance before you choose a train.

Xipu (犀浦) is a good departure station: the fastest trains reach Dujiangyan in 19 minutes and Qingcheng Mountain (青城山) in 23. The first train leaves at 06:06, and 71 train pairs run each day.^[5] Allow for the trip from your hotel to the departure station and the last leg to the entrance.

12306’s English service sells tickets to foreign passport holders. Buy with your passport details and carry the original passport: you show it at the station gates and to board, and there can be queues at security and ID checks.^[6] If you hire a car instead, agree the entrance, pickup point, waiting time and total price before you leave.

An ancient idea, maintained and changed

Li Bing, the Qin governor of Shu, led the construction around 256 BC, where the Minjiang leaves the mountains for the Chengdu Plain.^[2] The design uses the river’s course and the lie of the land to divert water for irrigation, drain sediment, control floods and regulate the flow, all without a dam. UNESCO inscribed Dujiangyan together with Mount Qingcheng in 2000.^[7]

What you see is a working system, not untouched ancient material. It was modified and enlarged under the Tang, Song, Yuan and Ming dynasties.^[7] Repairs and sediment clearing every winter keep it running, and around Qingming in early April a ceremony marks the release of water into the canals.^[1] Yuzui was the first part rebuilt in concrete, in 1935, and other structures followed.^[8] Its long life comes from clever design, steady management and constant adaptation.

Yuzui: dividing the river

Yuzui (鱼嘴), the Fish Mouth, is a dike in mid-river that splits the Minjiang into an inner channel for irrigation and an outer channel that carries the main flow and the floods.^[8] The split follows the water level. In low water about 60 percent goes into the inner channel and 40 percent into the outer one; in flood the main current rushes to the outer channel and the shares reverse.^[1] Watch how the flow divides, because it is not the same on every visit.

Feishayan: releasing excess water and sediment

Feishayan (飞沙堰), the Flying Sand Weir, is a second outlet from the inner channel. When the inner channel carries more water than the intake can take, the excess spills over it back into the main river. Together with the bend currents it sends about 70 percent of the sand entering the inner channel back out.^[1]

Baopingkou: controlling the intake

Baopingkou (宝瓶口), the Bottle Neck, is a passage cut through rock that limits how much water enters the irrigation network. When the incoming flow is too high, the excess escapes over Feishayan. The builders cut the rock by heating it with fire and cooling it with water.^[1] Seen together, the three structures are easy to read: divide, release, regulate.

Choose the walk for what you want to see

For the waterworks, head for Yuzui, Feishayan and Baopingkou and use the entrance map to link them. Pause where you can compare the inner and outer channels. Seeing how the three work together beats photographing each one on its own.

The site also has Anlan Suspension Bridge, Erwang Temple, Fulong Temple and Qinyan Tower.^[2] Add the bridge, a temple precinct or a viewpoint as your interests and the open routes allow, and keep extra time for uphill paths. If steps or a suspension bridge are a problem for you, ask the visitor centre for a suitable route before you start.

Should you add Qingcheng Mountain?

Qingcheng adds mountain scenery and a long Taoist temple tradition: UNESCO calls it the birthplace of Taoism, celebrated in a series of ancient temples.^[7] Give it a separate day if you want both the waterworks and the temples. For a combined outing, decide which part of the mountain you want, check its own entrance and admission, and allow for the transfer between the sites and the return journey. Keep the mountain visit short rather than counting on lifts or shuttles to make a full walk easy. See the Qingcheng Mountain guide to plan that second part.

Weather, payment and a comfortable visit

Pick your day by the local forecast and any scenic-area notices. Rain makes paths and river viewpoints slippery, so wear shoes with good grip and bring rain protection. Keep behind barriers, follow staff instructions near the water and leave enough daylight for your route and exit.

As of January 2026 the scenic area sells tickets to foreign visitors online in several languages and currencies, including English, Japanese, Korean, Thai and French, and foreign cards work at the ticket windows and in the souvenir shops. ATMs for major international cards give out RMB 10 notes, and the visitor centre has a translation screen for 14 languages. At Yuzui, multilingual audio guides explain how the water is divided.^[9] Bring drinking water, keep your booking confirmation handy and carry a backup payment method for small local purchases.
