what is the bus route from crowne plaza kunming city centre to stone forest please?

No direct public transportation can take you to the destination from the hotel.
So you are suggested to take a cab to get to East Bus Station first. The fare is about CNY 25. There are several coaches that can take you to Shilin Scenic Area Bus Station. They depart from 07:00 to 19:00 with the interval of 30 to 40 mins. The ticket fare is CNY 27 per person.
