Discover Feisha Weir: A Hidden Gem of Dujiangyan's Ancient Engineering

Location & How to Get There

Feisha Weir, a masterpiece of ancient Chinese engineering, sits quietly within the Dujiangyan Scenic Area in Chengdu, Sichuan. To reach this historic site, head to Lidui Park Road in Dujiangyan City—just a 1-hour drive from downtown Chengdu. If you’re traveling by public transport, take a bus or train to Dujiangyan Station, then hop in a taxi or local shuttle bus directly to the scenic area. Once inside, follow the signs to Feisha Weir, one of the core structures of the 2,000-year-old Dujiangyan irrigation system.

What Makes Feisha Weir Special?

Feisha Weir isn’t just a pretty name—it’s the “flood discharger” of the Dujiangyan system! Imagine a giant, smart-designed spillway that controls floodwaters while flushing out sand and rocks. This clever setup keeps the Chengdu Plain (where millions live) safe from flooding. Unlike other weirs, Feisha Weir uses natural forces: when water rises, it automatically diverts excess flow into the Min River, preventing disasters. It’s like a guardian of the plain, working tirelessly since 256 BC!

A Scenic Engineering Marvel

Though Feisha Weir itself is a functional structure, its setting is anything but dull. The weir sits along the Min River, surrounded by lush mountains and temples. For the best view, hike up to Erwang Temple (Second King’s Temple) on the hillside. From here, you’ll see Feisha Weir in action—watch how water rushes through its gaps during high flows, creating a mesmerizing “water curtain” effect. On clear days, the contrast of green hills, blue water, and ancient stone makes for postcard-worthy photos.

History Meets Nature

Feisha Weir isn’t just about nature—it’s a testament to human ingenuity. Built by Li Bing and his son (Dujiangyan’s legendary creators), this weir uses no moving parts but achieves perfect balance. The design includes triangular openings that slow water flow, allowing sand to sink while clean water flows into irrigation channels. Even today, local farmers rely on this system! Visit the nearby Dujiangyan Museum to learn more about its history, or watch guides demonstrate how the weir works using traditional tools.

Practical Tips for Visitors

  • Best Time to Visit: Spring and autumn offer mild weather. Avoid rainy seasons (July–August) if you’re not into dramatic flood scenes!
  • What to Bring: Comfortable shoes (you’ll do some hiking), a hat, and sunscreen. The area is mostly outdoors, so dress for the elements.
  • Guided Tours: Join a group tour to hear stories about Li Bing and the weir’s secrets. Many guides use English or multilingual audio devices.
  • Food & Rest: The scenic area has cafes and rest areas. Try Sichuan snacks like dandan noodles or spicy hotpot near the entrance.

Why Feisha Weir Should Be on Your Chengdu Itinerary

Even if you’re not a history buff, Feisha Weir offers a unique blend of nature, culture, and engineering. It’s less crowded than other Dujiangyan spots, making it perfect for quiet reflection. Plus, the hike to Erwang Temple rewards you with panoramic views of the entire valley. For a taste of ancient China’s wisdom and a chance to see history still working today, Feisha Weir is a must-see—trust me, you won’t find anything like it elsewhere!
