How do I go to Xishan Park from downtown Kunming

As I have no idea of your exact location, I can just give you a general suggestion:
take local bus no. 94 at Haigeng Park and get off at the terminal station - Gao Yao. Then you will be at the foot of the West Hill (Xishan).

If you’re around Cuihu Park, take bus 54 to Mianshan Che Chang Stop, and take taxi to the park, the taxi fee is 50CNY.
If you’re near the Medical Examination Center, You can take bus 73 from Desheng Bridge Stop to Dianchi College Stop, and then reach there by taxi; the taxi fare is about CNY60.
Besides, you can just take taxi from the city center, it cost about CNY70.
Since your specific location is unknown, I can only tell you so much. Wish you good luck!

Thank you very much! We will be staying at the Banyan Tree Hotel. I believe it is in the old town. I think we can get the rest from the hotel staff. Thanks again.
