We need to take a bus to stone forest. I think that Kunming East Bus Station is the correct.

1. Yes, you can take a bus to Shilin from East Bus Station. The trip takes about 1.5 hours.
2. From the south gate of the park, you may walk east for about 200 yards, and turn right. Walk south for about 400 yards to Wuyi Road (Provincial Talent Market) Station. Then, take bus line 237 to East Bus Station.
