The bus costs NT$90 round trip. When you get to Leshan, take a bus or take a taxi to the Big Buddha, which only costs about NT$20, and the entrance fee is NT$70, with a pass.

After that, you can stay in Leshan City. The average business hotel costs around RMB 80, and the conditions are not bad. You can go to Gaobaimen-Park area, where there are more snacks.

In the evening, you can stroll around the city and eat snacks (the snacks in Leshan are very good).

I'll see when you come back the next day.
