In Xishuangbanna, the city of Menglun is less than 100 kilometers east of the city of Jinghong. The city haven't got particularly great interest, but you will find a magnificent tropical garden:

There is the famous 'Xishaungbanna Tropical Botanical Garden Chinese Academy Of Sciences'. Admission is 60 yuans per person.

I strongly recommend this visit, the garden is beautiful, you have a pleasant time.

It's very easy to go in the day of Jinghong, in addition to the road is pretty.
