This trail connects the towns of Wanggu with Lingjiao (2km, 1h). It is a beautiful path inside the forest, which does not present much difficulty, although at some point it has a bit steep stairs (nothing that children do not do in the park :-).
When you get to the town of Lingjiao, keep left towards the train station, and soon you will pass Cai's House, an abandoned house from 1939, which surprises with its architecture.
Then you will go down a street with interesting drawings and on the left you will find the train station. There is a small shop there in case you need to buy water or snacks.
