Jiu Zhai Gou and Huang Long in Sichuan China are the most beautiful places that I had visited. I went during last autumn and there were 4 colors of trees. The trees on the top are in white, trees in the middle are in yellow and orange, trees at the bottom are in green. The lakes are crystal clear and the mountain/tree reflections on the lake are beautiful.

Do visit at my photo album on China (esp Huang Long) to look at beautiful pictures.
