Mt Siguniang（Chinese: 四姑娘山; literally "Four Girls Mountain or Four Sisters Mountain"; Tibetan name:Skubla）is the highest peak of Qionglai Mountains in Western China.It is located in the bordering area of Xiaojin County and Wenchuan County in Ngawa Tibetan and Qiang Autonomous Prefecture, Sichuan Province.
Mt Siguniang encompasses 4 peaks: DaFeng（Big Peak or 1st peak）, ErFeng(2nd peak), SanFeng（3rd Peak）, and Yaomei Feng (4th Peak). The highest peak is Yaomei Feng（Chinese: 幺妹峰; literally "peak of the youngest sister"）, also known as the ‘Queen of Sichuan’s peaks’（Chinese: 蜀山皇后）, standing at 6250 meters. It is also the second highest mountain in Sichuan Province. The first ascent was in 1981 by a Japanese team via the east ridge.Very few people attempt to climb this and very few of them succeed after that!
Mt Siguniang DaFeng (Chinese: 四姑娘山大峰or大姑娘山; literally "peak of the oldest sister"，5,025m) is normally considered a pure trekking peak while ErFeng (Chinese: 四姑娘山二峰or二姑娘山; literally "peak of the second sister"，5,276m) and SanFeng (Chinese: 四姑娘山三峰or三姑娘山; literally "peak of the third sister"，5,664m)is more challenging as it involves basic climbing technique.

Mt Siguniang National Park was identified as a UNESCO Heritage Site as part of Sichuan Giant Panda Sanctuaries in 2006. The park comprises Mt Siguniang and the surrounding three valleys, namely Changping Valley (Chinese: 长坪沟), Haizi Valley (Chinese: 海子沟) and Shuangqiao Valley (Chinese: 双桥沟), covering an area of 2,000sq km.
