is there a train or bus from changchun to Vladivostok ?

As I know, there is no direct train between these two places. You can take a tourist bus instead. In local Passenger’s Coach Center, you can take the long-distance bus to the city directly, and you are suggested to book the tickets in advance. The whole ride is about 16.5 hours.

Yeah, there is no direct train. You can take a train to Suifenhe first in 14.5h and then transfer to a cross-border coach to your destination. I suggest you prepare all traveling documents (visa and passport) in advance.

thanks, for the answer, do u know how much is the fare ofthe tourist bus to Vladisvostok, thanks

The fare is about CNY535 fpr independent tours (including Visa fare), and CNY335 for group tourists.
