The Red Leaf Valley sprawls for a total length of 11km at altitudes between 2,200m - 2,900m above sea-level. The area's dense vegetation coverage is mostly comprised of towering trees in the subalpine dark coniferous forests and conifer-broadleaf forests, as well as swaths of arrow bamboo, red birch and sea buckthorn, which serve as homes to a myriad of national Grade One and Grade Two protected animals like the golden snub-nosed monkeys of Sichuan and the red panda. The water that rushes down the valley turns into a very high and magnificent cascade. During the autumn, the colors of the season dye the forests in distinct layers of red, yellow and green. The blazing crimson leaves flutter around like souls of the snow mountain in all their glory. The best time for red leaves is between October and November.
