Lanzhou Steles Forest (兰州碑林 Lánzhōu Bēilín) is perched on top of the hills on the north side of the Yellow River. Entrance is free, if you bring ID. For some reason this is very important to the people at the gate, who were very reluctant to let us in last time we were there without ID. The steles here are stone tablets carved with poetry and calligraphy (in a variety of styles), related to life in the northwest of China. If you can't read Chinese you probably won't get much out of it. That said, the gardens are pleasant, and it's an impressive building, with a fantastic view of the city on a fine day.
