China – Twin Peaks Mt Siguniang (Dafeng + Erfeng)

China – Twin Peaks Mt Siguniang (Dafeng + Erfeng)

SGN Twin Peaks

The Four Sisters Mountain (also known as Siguniang Shan) Scenic Area is situated in Xiaojin County of A’ba Prefecture in Sichuan Province of China. The area is reputed to be the “Queen of Mountains in Sichuan” and “The Oriental Alps” because it offers beautiful landscape and exquisite scenery. The Four Sisters Mountain Scenic Area consists of Mt Siguniang, Mt Balang, and 3 main valleys – Haizi Gou, Changping Gou, Shuangqiao Gou.

Mt Siguniang is rise between Haizi Gou and Changping Gou. Mt Siguniang encompasses four peaks: DaFeng (Big Peak or 1st peak), ErFeng (2nd peak), SanFeng (3rd peak), and Yaomei Feng (4th peak). The highest peak is Yaomei Feng (幺妹峰); literally: "peak of the youngest sister"), also known as the "Queen of Sichuan's peaks" (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. The first ascent of the southwest ridge was made in 2008 by Chad Kellogg and Dylan Johnson. Thereafter a few attempts were made by local Chinese mountaineers, only a few successfully scaled to the top.

The other three lower peaks are regular mountaineering destinations through all seasons. Mt Siguniang DaFeng (四姑娘山大峰 or 大姑娘山; literally: "peak of the oldest sister", 5038 m) is normally considered as a pure trekking peak while ErFeng (四姑娘山二峰 or 二姑娘山; literally: "peak of the second sister", 5276 m) and SanFeng (四姑娘山三峰 or 三姑娘山; literally: "peak of the third sister", 5355 m) are more challenging as it involves basic climbing technique.

About The Climb

We combined both the 1st Peak and 2nd Peak treks into one trip. The two peaks shared the same access point starting from Rilong – Haizi Gou. We will first climb 1st Peak then followed by 2nd Peak of Mt Siguniang. 1st Peak of Mt Siguniang is rated as relatively easy trek, while 2nd Peak is more challenging with steeper rock formation nearer to the top.

Trekking Seasons

The climate in the high mountain region in southwest Sichuan, mainly the Aba Tibetan Autonomous region depends on the altitude. The climate is alpine and even arctic in the highest peaks. In the valleys, the dry season and the rainy season are obvious. May to September is the wet season, and October to April is the dry season.

The best time to climb Mt Siguniang is during the autumn and winter season from September to December. Mid October when the leaves change colour to the autumn hue of red, brown, orange and yellow is the best time to visit.

Experience Required

You should have good trekking background. You will be required to trek above 3000m on most of the days. On summit day, you will trek for long hours to an elevation of above 5000m; summit attempt will start between 3am and 4am using headlamps and can be very cold and windy. Having trekked above 4000m is an advantage. This is a camping trek, we will be sleeping in camping tents at both of the base camps.

Equipment and Gear

You will need thermal base layers, a fleece jacket and a water/wind proof outershell jacket for the trek.  When at the campsite, after sundown and during the summit trek, a down jacket will be required. A good down sleeping bag is also needed.

A packing list will be provided for all our participants. Sleeping bag and sleeping mat are provided. Please refer to our Resource Centre page to read about the layering system to be better prepared and choose the right gear/equipment for your climb.

Grading: 2C

Good cardio-vascular fitness is necessary. There will be several steep rock scrambling slopes to negotiate at closed to 5000m elevation. You should have the ability to trek with personal backpack load of between 5kg and 8kg for up to 12hrs or more on summit day. You will also be descending on scree slope that requires strong endurance fitness.

Training: Regardless of your level of fitness and physical conditions, it is advisable to train prior to embarking on a climb or trek. A training recommendation specific to the climb or trek will be given upon signing up. A good four to five months of training would be a good preparation for the trek. Refer to our Grading chart for an overview on the technical difficulty and fitness required for this trip.
