In less than two weeks my Chinese visa will expire and I'm considering taking one of the ferries to South Korea.
I don't care about which part of China it leaves from, there are several choices. I will buy the cheapest one-way ticket, I don't care if it means sleeping in a shared cabin, or even just getting a seat. Whatever is cheapest is fine. I also don't care where in Korea it lands, how long it takes, etc.
Wikivoyage has a bit of info on China to Korea and Korea to China, but I haven't been able to find something with all the prices so I can choose the cheapest. These are the places I can find which have ferries departing to South Korea, all to Incheon:
- Dalian, Liaoning
- Dandong, Liaoning
- Lianyungang, Shandong
- Qingdao, Shandong
- Rizhao, Shandong
- Rongcheng, Shandong
- Weihai, Shandong
UPDATE I just found an excellent map of ferry routes by chance Googling, but I don't know anything about it and it doesn't include prices.
