TL;DR
Mount Siguniang (四姑娘山) officially became a UNESCO Global Geopark on April 16, 2026. Known as "Four Girls Mountain" for its four snow-capped peaks, this location offers some of China's most dramatic mountain scenery. Foreign visitors should know: Yaomei Peak (Little Sister) is 6,247.8m, altitude sickness is a real concern, and the best seasons are spring (Apr-Jun) and autumn (Sep-Oct). This guide covers the legendary origin story, geological significance, and three practical hiking routes.
The Legend: How Four Girls Mountain Got Its Name
The Legend of Aba Langyi's Four Daughters
Long ago, a mountain god named Aba Langyi lived in what is now the Xiaojin County of Sichuan. He had four beautiful daughters who were as pure and bright as snow.
A demon named Moduo attempted to seize the beautiful valley where the family lived. When Aba Langyi refused to surrender his daughters, the demon unleashed a terrible flood to drown the land.
To protect the local people from the catastrophic flood, the four daughters transformed themselves into four snow-capped peaks, standing tall and proud to block the raging waters. Their sacrifice saved the valley below.
Local people called the peaks "斯古拉柔达" (Sigula Ruo Da) in the Gyalrong language, meaning "a mountain that shakes the sky." In 1971, during a nationwide geological survey, this name was transliterated into Chinese as "四姑娘" (Four Girls) — and Yaomei Peak, the highest, became known as "Little Sister."
Geological Wonders: Why UNESCO Recognized Siguniang
The UNESCO designation on April 16, 2026, recognizes Siguniang's exceptional geological heritage:
A Geological Timeline
- 350 million years ago: The area was submerged under the ancient Tethys Sea
- 200 million years ago: The Indosinian orogeny dramatically raised the seafloor
- 65 million years ago: The Himalayan orogeny began, pushing the region to its current heights
- Last 100,000 years: Rapid uplift created the dramatic peaks we see today
🌟 What Makes Yaomei Peak Special?
Yaomei Peak is considered one of the world's most difficult summits to climb. Its sharp granite face and unpredictable weather make it more challenging than Mount Everest for many technical climbers. The peak's distinctive pyramid shape is carved by glacial action over thousands of years.
Practical Information for Foreign Visitors
Best Time to Visit
| Season | What to Expect |
|---|---|
| Spring (Apr-Jun) | Wildflowers, mild weather, best for sightseeing |
| Summer (Jul-Aug) | Green valleys, but rainy season |
| Autumn (Sep-Oct) | Golden foliage, clearest skies, peak season |
| Winter (Nov-Mar) | Snow scenery, but cold and icy trails |
Altitude Warning
⚠️ Important: Altitude Sickness
The area ranges from 2,500m to 6,247m. Altitude sickness can affect anyone, regardless of fitness level. Symptoms include headache, nausea, and shortness of breath.
- Arrive 1-2 days early to acclimatize in Chengdu (500m)
- Stay hydrated and avoid alcohol
- Consider medication (consult your doctor before travel)
- Descend immediately if symptoms worsen
Three Hiking Routes Compared
🚶 Shuangqiao Valley (双桥沟) — Easiest
Most accessible valley with a scenic bus that stops at major viewpoints. Perfect for first-time visitors or those with limited time. Highlights include Five Color Lake (五色湖) and Red Cypress Forest (红杉林).
🥾 Changping Valley (长坪沟) — Moderate
The heart of Siguniang. Famous for its pristine forests, streams, and stunning views of Yaomei Peak. The trek to Elephant Trunk Mountain (木骡子) takes about 6-7 hours one way. Overnight camping possible.
🏕️ Haizi Valley (海子沟) — Challenging
Known for its high-altitude glacial lakes (海子). Elevation reaches 3,800m+ — altitude sickness risk is significant here. Popular for backcountry camping and serious hikers only.
How to Get There
From Chengdu:
- By bus: Chengdu's Xipu Bus Station (茶店子客运站) has direct buses to Siguniang Town (日隆镇), ~6-7 hours, approximately ¥120-150
- By private car: ~4 hours via Chengma Highway (蓉昌高速), more comfortable but requires a Chinese speaker or tour arrangement
What to Pack
- Warm layers (temperatures vary widely by elevation and time of day)
- Waterproof jacket (weather changes rapidly)
- Comfortable hiking shoes with good grip
- Sun protection (high altitude = intense UV)
- Water and snacks (limited facilities on trails)
- Passport (required for accommodation registration)
- Cash (ATMs are scarce in the mountains)
🎫 Entrance Fees (2026)
Ticket prices vary by valley. Combined tickets for all three valleys are available. Book accommodations in Siguniang Town (日隆镇) well in advance during peak season (National Day, May Day, autumn).
