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 of the beautiful mountain landscape and exquisite snow peaks 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 stands between Haizi Gou and Changping Gou. Mt Siguniang encompasses four peaks: DaFeng (Big Peak or 1st peak / 5038m), ErFeng (2nd peak / 5276 m), SanFeng (3rd peak / 5355m) and Yaomei Feng (4th peak / 6250m).

Yaomei Feng (幺妹峰); literally: "peak of the youngest sister", also known as the "Queen of Sichuan's peaks" (蜀山皇后). is the second highest mountain in Sichuan Province. The first ascent of Yaomei Feng was in 1981 by a Japanese team via the east ridge. Very few people attempt to climb Yaomei Feng and even fewer have succeed. The first ascent of Yaomei Feng from the southwest ridge was in 2008 by Chad Kellogg and Dylan Johnson. Thereafter a few attempts were made by local Chinese mountaineers with only a handful of them successfully scaled to the top.

The other three lower peaks DaFeng, ErFeng and SanFeng 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") and ErFeng (四姑娘山二峰 or 二姑娘山. Literally "peak of the second sister") are trekking peaks. ErFeng is more challenging and tougher than DaFeng with steeper rock formation nearer to the top. SanFeng (四姑娘山三峰 or 三姑娘山. Literally "peak of the third sister") has a fixed rope section near the peak and require rock scrambling for the summit section.

About The Climb

We combined both the Dafeng and Erfeng into a twin peaks itinerary. The two peaks shares the same access point in Haizi Gou. The first climb is Dafeng, followed by Erfeng. The trek to Dafeng Base Camp (4200m), through Haizi Gou, is a straight forward gradual ascent of around 6-8 hours. For better acclimatization, there is an acclimatization day at Dafeng Base Camp. The summit route is on rocky terrain and can be covered in ice and snow. After the summit (around 7-8 hours round trip) and a meal at Dafeng Base Camp, we will pack up to traverse across (1-2 hours) to Erfeng Base Camp. Erfeng's summit terrain is similar to Defeng's but steeper and more challenging. After Erfeng summit (around 7-8 hours round trip), descent to Erfeng Base Camp to rest and recover for the night. The last day of the trek, we descend through Haizi Gou to Rilong.

Trekking Seasons

The climate in Mt Siguniang area can be drastically different in the high peaks and valleys. In the high peaks the climate is constantly alpine and even arctic all year round. In the valleys, the dry season and the rainy season are obvious. April to September is the wet season. October to March is the dry season.

From April to May the rain dump massive amount of snow in the mountains creating knee deep soft snow terrain  that is difficult to walk on near the peaks. From June to August, which is also summer, the intensity of the sun melts the snow as quickly as they are being dumped by the rain. The rainy season also means gloomy and cloudy sky that obstruct the otherwise beautiful scenery.

The best time to climb Mt Siguniang is in autumn and winter from September to January. 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 above 4000m trekking experience. Rilong is located at 3160m. You will be trekking from 3160m to above 5000m and climbing two 5000m peaks in a short duration. The average personal backpack load you will be carrying during the trek is around 5-6kg.  While the approach trek is on easy mud & dirt trail, the summit trails for both Dafeng and Erfeng are rocky and can be covered in ice and snow. Erfeng summit trail is steeper and more challenging than Dafeng's. You will also be sleeping at above 4000m at both DaFeng's and Erfeng's base camps.

Equipment and Gear

You will need thermal base layers, a fleece jacket and an outer shell jacket. When at the base camp, after sundown and during the summit trek, a down jacket will help keep you warm. A down sleeping bag is also needed and provided.

A packing list will be provided to all our participants. Please refer to our Resource Centre page to learn about the layering system and choose the right gear/equipment for your trek.

Training: Regardless of your level of fitness and physical conditions, it is advisable to train prior to embarking on a trekking or mountain climbing trip.

Pure cardiovascular fitness is NOT enough.

Focus your training effort in the following areas, assuming that you are in good health and injury-free:

  1. Climbing conditioning – stairs and load training.
  2. Cardio training - Jogging/running and interval training like CrossFit or HIIT.
  3. Strength training for the lower body, shoulder, back and core
  4.  Flexibility training - eg: Yoga and stretching exercises

A good four months of training would be a good preparation for this trek.

A recommended training guide specific to the trek or climb will be given to you upon signing up.

Refer to our Grading chart for an overview on the technical difficulty and fitness required for this trek.
