The Dazhi River — a canal dug by hand

Forty kilometres of canal dug largely by hand in the 1970s, a rocket monument, salt-field geometry, and the best watermelons in the Yangtze delta.

The Dazhi canal in Pudong, cut across the coastal flats in the 1970s

The Dazhi River is not natural. It is a straight canal cut across Pudong in the late 1970s, largely by hand, to drain and irrigate the coastal flats.

That makes it the youngest landscape on this list by a wide margin — and the route along it is about farming, salt, and a district that was countryside within living memory.

It is also the easiest of the ten to reach, because Line 16 runs the length of it.

What the route passes

The Pujia mansion and the Huinan watchtower, the Jiaxiu bridge, the Dazhi River culture hall, and the estuary where the canal meets the sea. Further inland: Tangjia’an, Zhaoqiao village in Datuan and the Xi family house.

And at Laogang, the monument to China’s first experimental sounding rocket — which is exactly the kind of thing you find in coastal Pudong and nowhere else.

Salt, melons and field pattern

The geometry here is not natural either. The zaogang salt pans — rectangular evaporation beds laid out in a grid — still dictate how the fields are divided, centuries after the salt industry left.

This is 8424 watermelon country and Nanhui honey peach country. In season, the roadside is the point of the trip.

Length and pace

The published line is about 40 km; a 37 km, seven-hour version is the one the survey teams walked. Bike it if you want the whole thing — the towpath is flat and almost entirely straight.

Line 16 puts you at Huinan for the inland end and Lingang Avenue for the sea end.

Getting there without a car

The honest part

This is one of the city’s official countryside routes, not a ShanghaiWalk route. Distances are as published.

FAQ

Questions

Everything on this site is written and re-checked on the ground. When something changes, this page changes.

Why is there a rocket monument?

Laogang was a launch site in the 1960s; China’s first experimental sounding rocket went up from there. The monument marks it.

Is the towpath continuous?

Largely, yes, and it is dead flat. Expect occasional detours where work is going on — this is a working waterway.

Best time of year?

Late spring to early summer for melons and peaches. The canal itself is featureless and hot in midsummer.

Can I finish at the sea?

Yes — the estuary end is reachable from Lingang Avenue on Line 16, which makes a one-way walk genuinely practical.
