Will visit Tiger Leaping Gorge June 2013,any advice weather and local itineraries 7-10 days.

Generally, the average temperature then could be about 20C or a little higher. Rain will happen from time to time. So apart from the short-sleeved and long-sleeved shirts as well as a light coat, you have to prepare the rainy coat, too.

I used the agency to have a Kunming visit, including Lijiang and Tiger Leaping Gorge. It is fantastic.
