With crystal blue lakes, roaring waterfalls, lush green forests and snow-covered mountains, Jiuzhaigou is well known as a natural wonderland. Against this stunning backdrop, colorful Tibetan folk customs help create a truly exotic destination. Huanglong Park is famous for its multi-colored ponds of various shapes and sizes. These beautiful reflecting ponds are adorned in dreamlike hues of blue, green, yellow and brown. The colors are a result of natural minerals in the water and reflection of sunlight.
