Baihe is a city in Jilin Province.
The Yanleyuan Restaurant, opposite the train station, has good food, serves local specialities such as mushrooms and rare fungus, and the restaurant-owner is the man to see for arranging any activities within the local area.
A alternative is to ask around the little family restaurants by the station. Many of them have rooms where you can stay for as little as ¥10 per person. The restaurant owners would appreciate it if you keep a low profile, as the PSB disapproves of foreigners using this option. .
The train is the best way to leave the Changbaishan region, although there is supposedly a bus that leaves every morning at 6.30am for Jilin (7hr; ¥41) and then on to Changchun (12hr; ¥49).
