Where can I find a tour group from Changchun to Changbai Mountain? I hope everyone can help me.

There is a direct train to Changbai Mountain in Changchun, K7388/K7389 Changchun-Baihe 14:33-05:48 15 hours 15 minutes, hard sleeper 5310. If you are not in a hurry after getting off the bus, you can find a hotel in Erdao Town, next to the railway station. Hotels can generally contact the mountains. If you don't join the group, the one-way fare to the mountain is generally around 30 yuan. Just buy a ticket at the mountain gate. I can't remember around 200 yuan, including big tickets+environmental protection bus+peak stop bus (cheetah, Mercedes-Benz bread, GMC). In short, there is no extra money to go up the mountain.

You can also take the train to Yanji and sign up for a tour. There are many travel agencies.
