By bus, you can take the 1 line to Wenshui Road Station, and then transfer to Shen Chong 1 (note the difference between Nanmen and Chenjia Town).
The advantage of going to the south gate is that it is convenient to transfer to different scenic spots for accommodation. The fare to Shen Chong is 20 pounds.
The advantage of going to Chenjia Town is that it is suitable for a one-day trip to Dongtan and Forest Park, because Chenjia Town is in the easternmost part of Chongming, you can refer to the map, and the fare is 12.
Recommended: Dongping Forest Park (the fare is 70 yuan), Dongtan Wetland (I don't know), Xisha Wetland (free for the time being), Qianwei Village (providing catering accommodation and farmhouse music), Genbao Football Base (it is said that wonton is good), and villagers' hostels everywhere in Chongming are also good scenery. There is also the only Catholic church in Chongming by the port.
Hotel: The most convenient is the motel in the south gate 168, and then you can stay at the farmhouse in Qianwei Village (you'd better contact yourself in advance). There are basically small hotels in the city.
Ps: There are many people on May Day, and there are many people driving. Go on road trip will be a tragedy, believe me.
It is better to drive by yourself. The Yangtze River Bridge used to be Chenjia Town, so just walk along the Chen Hai Highway mentioned above. Of course, there is no car, and it is good to take a boat. Now it seems to run every hour, so there should be no bus congestion. Baoyang Wharf is the distance from Baoyang Station of Line 3. There are Wusong Wharf and Shidongkou Wharf. Since I haven't done this myself, please don't try it easily.
All right, it's almost time. I hope the trip goes smoothly and you have a good mood all the way.
