I have a plan to travel to Jiuzhaigou, Huanglong and Emeishan next year 2014. But I only have a choice to travel there in late March or/and mid-May 2014, though I have seen most of the recommendations that autumn is the best time to visit.
So, would like to get some advises which of the months March and May will give a better sceneries for each of the locations. Any recommendations? trying to make this a worthwhile trip :)
