What's the best way to travel from Harbin to Changbai Mountain with some friends? Where is the most convenient place to get off at An, Dunhua and Yanji? I want to see both the north slope and the west slope. I am a pick-up driver in Changbai Mountain, and I can provide accommodation and car rental. You can book hotels on various slopes, and you can save money by taking the train to Dunhua. When the bus from 27 yuan and Dunhua to Fusong crosses Songjiang, get off and go to Xipo first, and get 2 10 tickets to the destination. If I see Tianchi on the west slope, I can skip Tianchi and transfer to an off-road vehicle on the north slope. Everyone is in 80 yuan. The next day, I will rent a car or take a train to the north slope. After swimming the north slope, I returned to Harbin from Baihe via Dunhua. 2. You can also visit the north slope first, take a bus from Dunhua to Baihe 3 1 yuan, take a car from Baihe for more than 20 minutes to the north slope, take a train to Songjiang at night, take a hard seat for 8 yuan, and take a car for half an hour to the west slope the next day, or rent a car directly from the north slope down to Songjiang. The cold water spring near the entrance of the north slope and the Changbai Mountain Museum in the valley floating stone forest are all worth seeing. One ticket for 40 yuan and one ticket for 370 yuan on the North Slope.
