Banna and Dali, Lijiang and Lugu Lake.
I suggest flying to Lijiang first. It is more expensive to fly to Kunming. Lijiang, Lugu Lake, Dali. Then go from Dali to Kunming. From Kunming to Banna.
It gets hotter in late May. Just wear a skirt and a short-sleeved coat. Because it will get cold sooner or later. Yunnan has a high altitude, so you should take sun protection all year round. Draw whether it&;s raining or cloudy. Mainly due to strong ultraviolet rays.
