Erhai Lake, Dali: Cycling the Corridor and Choosing a Shore

Erhai is best seen in two halves. The west shore, between the lake and Cangshan, has a car-free ecological corridor for cycling past fields and Bai villages, and you can ride out from the old town in the morning. The east shore is steeper and rockier, with Shuanglang and its lakeside guesthouses, and it is better reached by car with a night's stay. Doing the whole ring in one day is possible in a car but leaves no time to stop. If you have a single day, pick one shore. The lake is Yunnan's second-largest freshwater lake, about 250 square kilometres, 42.6 kilometres long and up to about 9 wide. It averages 10.5 metres deep and reaches about 20.9 metres at its deepest, and it drains west through the Xi'er River. The full trip plan is in the Dali travel guide.

The corridor and why the old lake road is gone

If you read about Erhai in older blogs, you will find a lakeside road lined with cafes and guesthouses. Much of that has gone. From 2018, as part of a clean-up of the lake, buildings inside the protection line were cleared and more than 1,800 households were moved back from the shore. The old ring road was replaced by the Erhai Ecological Corridor: 129 kilometres of wetland buffer, cycle track and footpath right around the lake. It is made up of 46 kilometres on the west shore, 69 on the east and 14 at the north and south ends.

Under Dali city's corridor rules, private cars, pets and unapproved commercial e-bikes are barred from the core sections. The west shore from Yangnanxi up to where the corridor meets the Dali–Lijiang road is one of them. Licensed battery sightseeing carts run along parts of it for a per-kilometre fare. Cars use the parallel public roads a little inland. In 2024 the corridor recorded more than 21 million visits, so the most popular stretches near the old town are busy at weekends.

The west shore by bike

This is the classic Erhai day: Cangshan on one side, water on the other, and villages, wheat or rice fields and small wetland parks in between. The full west section runs about 46 kilometres from Yangnanxi in the south to Taoyuan pier in the north. You do not need all of it.

• Caicun to the Panxi "S-bend" (about 9 kilometres). Caicun is the lakeside village directly east of the old town and the usual starting point. The S-shaped curve of track at Panxi is the most photographed stretch.
• Caicun to Haishe Park (about 26 kilometres). A longer half day running north along the shore toward the Xizhou area. You can stop for Xizhou itself if you leave the corridor and go a short way inland.
• Yangnanxi to Caicun (about 12 kilometres). The southern stretch, the first to open, and a little quieter.

Ride out and back, or ride one way and take a taxi from a village road back to the old town. Rent from the marked outlets so you can return the bike where you took it. Check the battery range, brakes and helmet before you leave. Lake wind and steady pedalling drain both batteries and legs faster than the map suggests. Bikes are allowed only on the cycle track, not on boardwalks, wetland or grass.

The east shore by car

The east side is drier and hillier, with headlands, inlets and small fishing villages. Shuanglang is the main stop, about an hour by car from the old town, and Wase lies further south along the same shore. Boats to Nanzhao Isle of Customs leave from the Shuanglang pier. Sunrise is the reason to sleep here: the sun comes up over the eastern hills behind you and lights Cangshan across the water.

You can drive the east shore in an afternoon with a hired car and driver, but the overnight is what makes it worthwhile. Shuanglang's lanes are narrow, so park outside the village and walk in with a small bag.

Which shore, if you only have one day

• Choose the west shore for cycling, Bai villages and paddies, an easy start from the old town, and a possible add-on of Xizhou.
• Choose the east shore for cliffs and inlets, the guesthouse night and sunrise, and if you are happy to spend part of the day in a car.

With two lake days, do the west shore by bike on the first, and drive to Shuanglang on the second for the night.

Light, wind and weather

Winter and early spring, the dry season, give the clearest view of the Cangshan wall across the water, but the wind is strongest then, especially at the Xiaguan end. Summer brings haze, afternoon showers and greener fields. Sunrise is best from the east shore looking west at the mountain. Late afternoon from the west-shore fields gives warm light across open water. Wherever you are, UV at nearly 2,000 metres is intense, and there is little shade on the corridor. Take a hat, sunscreen, water and a windproof layer.

Being a good visitor

• Stay on the marked track and paths. The wetland buffer exists to filter runoff before it reaches the lake.
• Do not swim, fish or camp where signs prohibit it, which is most of the shore.
• Pull fully off the track before stopping for photographs, because riders come through fast.
• Drones are restricted along crowded stretches and villages. Check the signs.
• If a corridor steward asks you to dismount or turn round, do it.

Frequently asked questions

Can I cycle all the way round Erhai?

In theory the corridor runs right round the lake, about 129 kilometres, but most visitors ride sections of the west shore and use a car for the east. A full ring by bike is a long, hard day.

Are cars allowed on the Erhai corridor?

No. Private cars are barred from the corridor. They use the public roads that run parallel a little inland.

Where should I start cycling?

Caicun, east of Dali Old Town, is the usual starting point, with the Panxi S-bend about 9 kilometres north.

Should I stay a night by the lake?

If Erhai is a priority, yes. A night in Shuanglang gives you sunset and sunrise without day-tripper crowds.
