May I know which bus to take to Stone Forest and how much is the fare.How long is the journey?

From KM East Bus Station, you can find the direct buses to reach stone forest in about an hour to an hour and a half.
The bus fare is 29RMB per person.

Thanks for the answers.I presume you have been there.Any advise on places,things or events that I should not miss in KM, Dali or Lijiang.

In KM city, apart from STone Forest, you cannot miss Dianchi Lake, Western Hills and World Horticultural Expo Garden.

For Lijiang, never miss Lijiang Old Town (and West Street), Jade Dragon Snow Mountain and Tiger Leaping Gorge. Imprssion Lijiang show is also worth time.

For Dali, I just know the Dali Ancient Town is famous.
