Dujiangyan Irrigation System: Complete Visitor's Guide

Most ancient water projects are ruins. Dujiangyan (都江堰) is not. Built in 256 BC without a single dam or pump, this irrigation system still feeds nearly 12 million acres of farmland — an area roughly the size of three Luxembourgs. Listed as a UNESCO World Heritage Site alongside Mount Qingcheng in 2000, it turned the flood-ravaged Chengdu Plain into China's legendary "Land of Abundance."

Getting There and Tickets

[图:都江堰景区正门入口.jpg]

From Chengdu by Train

The Chengdu–Dujiangyan Intercity Railway (成灌快铁) is the fastest and cheapest option. Board at Xipu Station (犀浦站) for the quickest ride — about 20–25 minutes to Lidui Park Station (离堆公园站), which is a 15–20 minute walk through Guanxian Old Town to the scenic area's south gate. You can also get off at Dujiangyan Station (都江堰站), better if you're heading to the north gate or Fish Mouth first. Fare is around ¥10 from Xipu. Trains from Chengdu Station (成都站) take 30–40 minutes and cost slightly more. During peak hours, trains run every 5 minutes.

By Taxi or Ride-hailing

From central Chengdu, expect 1–1.5 hours and ¥150–250. Works well for groups splitting the fare or travelers with luggage. Parking is available near the scenic area.

By Tourist Bus

Xinnanmen Tourist Bus Station (新南门旅游客运站) runs direct coaches — about 1.5 hours, around ¥30. Limited departures though; the train is more reliable.

Tickets and Hours

Reservations: Real-name booking is required — you'll enter by scanning your ID at the gate. Book 1–3 days ahead on the WeChat official accounts 青城山都江堰 or 悦游都江堰, or through Trip.com. Advance booking is critical during Qingming, May Day, National Day, and summer holidays.

Combo ticket: Dujiangyan + Mount Qingcheng costs around ¥220 and is valid for two days.

Discounts: Children under 6 (inclusive) or under 1.3 m enter free; ages 6–18 get half price; 65+ enter free year-round; ages 60–64 enter free on non-holidays, half price on national holidays. Same policies apply to foreign visitors.

How It Works: 2,280 Years Without a Dam

[图:都江堰鱼嘴分水堤全景航拍.jpg]

Li Bing's Challenge

In 256 BC, the Qin state had just conquered Shu (modern Sichuan) and urgently needed the Chengdu Plain to become a breadbasket for its wars of unification. The problem was the Min River (岷江) — a torrent from the Tibetan Plateau that flooded the plain in summer and ran dry in winter.

Li Bing (李冰), governor of Shu Commandery, rejected the obvious solution of building a dam. The Min carried too much sediment and surged too violently — any rigid dam would eventually be destroyed or silted shut. Instead, he designed a system that works with the river: letting the water split itself, flush its own sediment, and regulate its own flow.

That principle — working with nature rather than against it — is why Dujiangyan has survived 2,280 years.

The Three Components

The entire system runs on three interlocking structures, each solving a specific problem:

[图:都江堰鱼嘴分水堤近景.jpg]

Fish Mouth Levee (鱼嘴)

A fish-shaped dividing ridge splits the Min River in two: the Outer River (外江, the original channel) and the Inner River (内江, the irrigation channel). The genius is in the ratio: during the dry season, the Inner River receives about 60% of the flow to keep crops watered. When summer floods arrive, the rising water level and river-bend dynamics reverse the split — the Outer River absorbs roughly 60% instead. No valves, no human intervention.

Flying Sand Weir (飞沙堰)

If the Fish Mouth is the "splitter," the Flying Sand Weir is the "safety valve." This low overflow dam lets excess water in the Inner River spill back into the Outer River when levels get too high. Even more clever: the river's current creates a vortex at the bend that flings heavier sediment and gravel outward — roughly 80% of sediment gets ejected through the weir, keeping the irrigation channels clear.

[图:飞沙堰溢洪道.jpg]

Bottle Neck Channel (宝瓶口)

Li Bing's workers hand-carved a narrow gap through Yulei Mountain — shaped like a bottle neck — to control how much water enters the Chengdu Plain. No matter how much water comes from upstream, the channel's fixed width limits the flow. Anything beyond that capacity gets handled by the Flying Sand Weir. The severed half of the mountain still stands beside the channel — locals call it Lidui (离堆) — and you can clearly see the ancient chisel marks on its face.

Still Running Today

Dujiangyan is not a museum piece. It currently irrigates nearly 12 million acres of farmland (1,194.5 万亩 as of the 2026 spring planting season), spanning 8 cities and 41 counties across the Min, Tuo, and Fu river basins, serving over 30 million people. Chengdu earned its nickname "Land of Abundance" (天府之国) — literally "Heavenly Storehouse" — entirely thanks to this system.

Walking Route Through the Site

[图:景区步道沿河.jpg]

Start from the south gate (Lidui Park entrance) — this is the classic route, walking upstream from the "result" (seeing how Bottle Neck Channel controls the water) to the "cause" (the Fish Mouth's splitting design). It makes the engineering easier to grasp.

Recommended Route (3–4 Hours)

Stop 1: Lidui Park Entrance → Fulong Temple (20 min) Enter through the south gate and walk through Lidui Park to Fulong Temple. This is the best vantage point for Bottle Neck Channel — the platform in front of the temple gives you a direct view of the Min River being squeezed through the narrow gap. Inside, see the Eastern Han dynasty stone statue of Li Bing, then continue along the path upstream.

Stop 2: Bottle Neck Channel → Flying Sand Weir (15 min) Walk past the Bottle Neck Channel's carved rock face (look for the 2,000-year-old chisel marks on the left cliff wall), then reach the Flying Sand Weir. Stand on the weir to see both the Inner and Outer rivers simultaneously.

Stop 3: Flying Sand Weir → Anlan Bridge (20 min) Continue upstream to Anlan Suspension Bridge, which crosses the Inner River. The bridge sways as you walk — more on that below.

[图:安澜索桥横跨内江.jpg]

Stop 4: Anlan Bridge → Fish Mouth Levee (15 min) Cross the bridge and turn right to reach the Fish Mouth — the heart of the entire system. Stand at the tip and watch the Min River split in two. Spend 15–20 minutes here.

Stop 5: Fish Mouth → Erwang Temple (30–40 min, including visit) Climb the stone steps from the Fish Mouth up to Erwang Temple. The temple's front platform offers a bird's-eye view of the entire system's spatial layout — this is the single best angle for understanding how the three components fit together. See the "Beyond the Water" section below for what's inside.

[图:二王庙全景.jpg]

Stop 6: Yulei Pavilion (optional, add 30 min) The highest point in the scenic area. On a clear day, you can photograph all three engineering components in one panoramic shot. Take the escalator if you don't want to climb — details below.

[图:玉垒阁远眺都江堰全景.jpg]

Return: Retrace your steps back across Anlan Bridge and follow the riverside path to the south gate. Or exit through the north gate and walk to South Bridge / Guanxian Old Town.

Beyond the Water: Temples, Bridges, and Viewpoints

[图:伏龙观近景.jpg]

Fulong Temple

A Daoist temple built atop Lidui — the mountain fragment left after Li Bing carved out Bottle Neck Channel. Legend says Li Bing subdued a dragon here while taming the river. The main hall houses an Eastern Han stone statue of Li Bing, unearthed from the riverbed in 1974. Carved in 168 AD (Jianning Year 1), it stands 2.9 meters tall, weighs about 4 tons, and shows Li Bing holding a cha (a digging tool). The inscription on his robe reads 故蜀郡李府君讳冰 — "The Late Governor Li of Shu Commandery, named Bing." The temple also has a scale model of the entire irrigation system, helpful for understanding how the three components work together.

[图:伏龙观内东汉李冰石像.jpg]

Anlan Suspension Bridge

Believed to date back to the Warring States period (contemporary with the irrigation system itself), with the earliest confirmed written record from 990 AD (Song dynasty). Destroyed and rebuilt many times, the current bridge is a replica using steel-reinforced cables in the style of the original bamboo ropes. Recognized as one of China's five great historic bridges, it stretches about 286 meters across the Inner River. Walking across, you'll feel the bridge sway with each step while whitewater rushes below — it's also a great photo spot for the rapids and distant mountains, best light before noon. If heights aren't your thing, there's a concrete walkway bridge nearby that gets you to the same side.

Erwang Temple

Built during the Northern and Southern Dynasties (roughly 5th century) and renovated through the ages, this temple honors Li Bing and his son Li Erlang (李二郎). The complex climbs the hillside in terraced layers, with views of the river from multiple levels.

The most important things inside are the water-management inscriptions from various dynasties. The six most critical characters come from Li Bing himself: 深淘滩、低作堰 — meaning "dredge the riverbed deep, keep the weirs low" (if the weirs are too high, water can't escape and flooding returns). This maintenance principle has been followed by every generation of water engineers for over two thousand years — it's still the guiding rule during annual repairs today.

[图:二王庙治水碑刻.jpg]

Yulei Pavilion

The highest point in the scenic area, rebuilt after the 2008 Wenchuan earthquake. On a clear day, the views are extraordinary — look down to see all three engineering components in their spatial relationship, or east across the Chengdu Plain stretching to the horizon. Best visited before sunset, when warm light gives the river and mountains beautiful depth. Access: hike up in about 20 minutes, or ride the Buyunlang escalator (¥20 one-way / ¥30 round-trip, 128 m total length, two sections).

South Bridge

[图:南桥夜景.jpg]

A covered gallery bridge just outside the south gate — free to visit (not inside the ticketed area). By day, it's an ornate traditional bridge with carved beams and painted eaves. After dark, warm yellow lights reflect off the Inner River's surface, creating Dujiangyan's most photogenic night scene. Perfect for dinner and an evening stroll after visiting the scenic area.

What Most Visitors Miss

Annual Repairs: A 2,000-Year Maintenance Tradition

Every winter during the dry season (typically December through March), Dujiangyan undergoes a major overhaul called 岁修 (suìxiū — "annual repair"). Workers drain the Inner River, dredge the riverbed, patch the levees, and clear the channels. This maintenance schedule has continued unbroken since Li Bing's time, still following his six-character principle (see the Erwang Temple section above).

Winter visitors who catch the repair season get a rare sight: the Inner River's exposed riverbed, with the pebble foundation and engineering substructure normally hidden under water laid bare.

Macha Damming: Living Ancient Technology

[图:杩槎竹笼截流技术.jpg]

When workers dam the Inner River for repairs, they don't use modern sluice gates. They use 杩槎 (màchā) — an ancient temporary damming technique where thick wooden tripods are erected in the riverbed and the gaps filled with bamboo cages packed with stones. When maintenance is done, the tripods are chopped down to release the water — this is the origin of the Water Release Festival ceremony. This technique has been in active use for over 2,000 years and is still employed during annual repairs today.

The Stone Rhinoceros: From Legend to Excavation

Legend has it Li Bing carved five stone rhinoceroses to suppress water spirits. In late 2012, construction workers at Tianfu Square (天府广场) in central Chengdu accidentally unearthed a massive stone rhinoceros from the late Warring States to early Qin-Han period — 3.3 meters long, weighing about 8.5 tons. Its dating matches Li Bing's era. The rhinoceros is now displayed at Chengdu Museum (成都博物馆), right beside Tianfu Square — a tangible link between the Dujiangyan legends and archaeological evidence. Worth a visit on your way back to Chengdu.

Water Release Festival

Every year around Qingming Festival (usually early April), Dujiangyan holds the Water Release Festival (放水节) — a ceremony reenacting the ancient tradition of chopping down the macha tripods and releasing the Inner River's water after annual repairs. The event features a grand costumed ceremony honoring Li Bing, with thousands of spectators. Originating in the Northern Song dynasty, this tradition is over a thousand years old and was listed as a National Intangible Cultural Heritage in 2006. The moment is visually spectacular: on command, the tripods are cut, and river water surges into the Inner River channel.

Guanxian Old Town

[图:灌县古城街景.jpg]

The old town just outside the south gate — this is the former Guanxian (灌县) county seat. Narrow alleys, traditional teahouses, and local street food give it more authentic local character than Chengdu's touristy Wide and Narrow Alleys. Come here for lunch or dinner, then walk over to South Bridge for the evening light show.

Best Time to Visit and Photo Tips

Seasonal Guide

Beating the Crowds

• Weekdays are dramatically better than weekends — the difference in-park is night and day
• Qingming, May Day, and National Day are the three worst periods — Anlan Bridge alone can mean 30+ minutes of queuing
• Arrive at 8:00 AM when the gates open and finish the Fish Mouth and bridge photos by 10:00, before the tour groups flood in

Best Photo Spots

• Fish Mouth tip: The classic shot of the Min River splitting in two — morning light is best (facing east)
• Middle of Anlan Bridge: Rapids below, mountains behind — hold your phone steady, the bridge sways
• Erwang Temple platform: Best mid-range vantage point for the overall layout
• Yulei Pavilion top floor: The only spot that captures all three components in one panoramic frame — arrive before sunset
• South Bridge: Night photography — bring a tripod or use your phone's night mode

Adding Mount Qingcheng

[图:青城山山门.jpg]

Dujiangyan and Mount Qingcheng (青城山) are only 15 km apart — a 20-minute taxi ride — making them an easy same-day combo.

Is One Day Enough for Both?

If you have a full day (leave Chengdu at 7 AM, return by 7 PM), you can do both, but it'll be tight. Suggested pace: morning at Dujiangyan (3–3.5 hours) → taxi to Mount Qingcheng Front Mountain (20 min) → afternoon hike (2.5–3 hours) → back to Chengdu by evening.

With more time (say, staying overnight in Dujiangyan), you can take one day per site for a more relaxed experience.

Front Mountain vs. Back Mountain

For a day trip combined with Dujiangyan, choose the Front Mountain. The Back Mountain takes half a day or more on its own — not enough time when paired with Dujiangyan.

Eating in Dujiangyan

[图:都江堰本地特色菜.jpg]

Guanxian Old Town / South Bridge Area

This is the best area for food near the scenic area. The old town's back alleys are full of local restaurants, and both sides of South Bridge have dining options. Try these local specialties:

白果炖鸡 (Ginkgo Stewed Chicken) — Dujiangyan's signature dish, made with locally grown ginkgo nuts simmered with chicken until the broth turns golden, the meat falls apart, and the ginkgo is soft with a slight bitterness. Available at most local restaurants.

葱葱卷 (Scallion Rolls) — A Dujiangyan street snack: thin dough wrappers filled with shredded radish and lettuce, rolled up and dipped in a house-made sauce. Sold everywhere in the old town.

青城泡菜 (Qingcheng Pickles) — Fermented vegetables from the Mount Qingcheng area, tangy and crisp — a celebrated variety of Sichuan pickles and the perfect rice companion.

尤兔头 (Spiced Rabbit Head) — Braised and spiced rabbit heads, a Sichuan delicacy with several old shops in Dujiangyan. Requires some courage for first-timers, but the flavor is genuinely excellent.

Inside the Scenic Area

Options inside the park are limited and overpriced. Bring water and snacks, and save your proper meal for Guanxian Old Town or the South Bridge area.

Beyond This Guide

Dujiangyan works beautifully as part of a longer Sichuan itinerary — combine it with Chengdu's pandas, Leshan Buddha, or a few days exploring the Sichuan countryside. We can help you design a route that makes sense for your schedule and interests.
