Summer can be quite hot, Kunming day time almost comparable to Singapore but nights very cooling. Approaching rainy season now. I like high altitude locations like Shangri-La, sibei shiok to sleep at night.
It's about 12-day trip ( Kunming, Dali, Lijiang & Shangri-La ) but not enough time to cover all the locations I like. Yes, some places really very scenic like Pudacuo National Park in the morning hours. Very serene.
Hint: If you take Scoot and its unearthly flight hours, there's an area between the Arrival and Departure floors at Kunming Changshui Airport where you pay a small fee ( 20 / 25RMB ) to sleep until 7am next morning instead of paying for hotel. Only found out when I go explore their airport while waiting for return flight.
