Red Sequoia Forest Siguniang Mountain: Glacier Views & Autumn Foliage

At the head of Shuangqiao Valley in Mount Siguniang (Four Girls Mountain) Scenic Area, the Red Sequoia Forest (Hongshanlin) stands as the grand finale of one of Sichuan’s most dramatic alpine routes. Reaching this spot at 3,840 meters (12,598 feet) requires no hiking—a sightseeing bus drops you directly at the forest edge.

From there, a network of wooden boardwalks leads you into a world where ancient trees meet hanging glaciers and jagged peaks. The main draw is the endemic Sichuan Red Sequoia (Larix mastersiana), a living fossil that turns a fiery red in autumn, earning the forest its nickname “Flame of the Plateau.” This article covers why you should go, when to skip, who it suits best, and how to plan a safe visit at altitude.

Why Visit Red Sequoia Forest

Red Sequoia Forest offers three experiences that few other Sichuan highland attractions combine: easy access to primeval forest, unobstructed glacier views, and a dramatic seasonal color change. Because the sightseeing bus terminates here, even travelers with limited time can immerse themselves in a high-altitude forest without a demanding trek. The site also carries cultural significance—local Jiarong Tibetans regard the trees as sacred, and you’ll find prayer flags and Mani stones woven into the landscape.

Who Should Go

• Autumn foliage enthusiasts – October to early November is peak color.
• Photographers – contrasts of red forest, white peaks, and blue skies.
• Families with children – short, flat boardwalks; no strenuous climbing.
• High-altitude first-timers – bus access reduces physical strain; still, monitor altitude sickness.

Who Should Skip

• Travelers intolerant of altitudes above 3,500m – symptoms can appear quickly.
• Those seeking solitude – the bus drop-off area can be crowded midday.
• Winter visitors without snow gear – trails may be icy; views are more monochrome.

Practical Information

Altitude and Safety

At 3,840 meters, the forest sits at the highest point serviced by the Shuangqiao Valley sightseeing bus. This is a genuine highland environment. Common symptoms include headache, dizziness, and shortness of breath. Recommendations:

• Ascend gradually from lower elevations (e.g., overnight in 2,500–3,000m towns like Wolong or Rilong).
• Walk slowly on the boardwalks. No running.
• Carry portable oxygen if you are prone to altitude sickness.
• Stay hydrated. Avoid alcohol the night before.
• If symptoms worsen, descend immediately (the bus returns frequently).

Access and Effort

The forest requires no hiking to reach. From the Shuangqiao Valley entrance, take the scenic area’s internal bus to the final stop. The ride takes roughly 40 minutes and passes other viewpoints. Once at the forest, wooden boardwalks extend for about 2–3 kilometers (estimated) through the trees. Plan for 2–3 hours including bus travel and walking.

Best Seasons

• Summer (June–August): Lush green forest; meltwater waterfalls visible from glaciers. Pleasant temperatures but afternoon thunderstorm risk.
• Autumn (October–November): Peak color in mid-to-late October to early November. Needles turn gold and red. Chilly mornings, bright afternoons.
• Winter (December–March): Snow-covered; trees are bare. Stark beauty, but boardwalks can be slippery. Very cold.
• Spring (April–May): Less dramatic; snowmelt, early green shoots.

The Sichuan Red Sequoia – A Living Fossil

The forest’s defining tree is the Sichuan Red Sequoia (Larix mastersiana), a conifer endemic to the mountains of western Sichuan and a national grade II protected plant. Unlike common larches, this species has reddish-brown bark and grows straight upright. It is considered a “living fossil” from the Quaternary glaciation—its ancestors date back millions of years.

The trees form a dense stand covering hundreds of acres, with some individuals over a century old. The boardwalk winds past thick moss, fallen needles, and occasional clearings where you can see the full height of the trees against the peaks.

Because the forest is at the base of a natural amphitheater of cliffs, the microclimate stays cool and moist, supporting a rich understory of shrubs and wildflowers in summer. The air is noticeably fresh—locals call it a “natural oxygen bar,” though scientific measurements of negative oxygen ions are not verified. Regardless, the stillness and scent of pine and damp earth create a calming environment.

Glaciers and Mountain Views

From the forest floor, you look up at the Jade Hare Peak (Yutu Feng) and Hunter Peak (Lieren Feng). These are the highest peaks in the Siguniang massif that are visible from this angle. Hanging glaciers cling to the north- and east-facing cliffs.

In summer, meltwater cascades in thin white streaks, joining the stream that runs along the valley floor. The contrast between the warm reddish forest and the cold blue-white ice is one of the area’s most photographed scenes.

No glacier trekking is possible from the forest. The view is purely scenic. For closer glacier access, you would need a multi-day trek into the high basins, which requires permits and guides.

Cultural Context

The Jiarong Tibetan people who live in the surrounding villages consider the Red Sequoia Forest a sacred site. According to local legend, four goddesses (the “four girls” of the mountain) threw fire seeds to protect the valley from demons, and those seeds sprouted into the red sequoias. Whether or not you subscribe to the myth, you will see evidence of reverence: prayer flags strung between trees, Mani stone piles, and occasional remnants of smoke from wei sang (purification incense burning).

Visitors should treat these objects with respect. Do not move or climb on Mani stones. Photography of prayer flags is generally fine, but avoid intrusive close-ups of individuals performing rituals.

Photography Tips

Red Sequoia Forest is a photographer’s destination, especially in autumn. Key advice:

• Morning light (before 10 a.m.) hits the peaks and forest with warm, angled rays. Shadows are long and texture pops.
• Autumn colors peak around October 25–November 5, but vary by year. Check recent visitor reports.
• Wide-angle lens for forest + glacier composition.
• Polarizing filter to reduce glare on glacier ice and enhance red tones.
• Tripod useful in low-light boardwalk sections, but be aware of crowds.
• Avoid midday overhead sun flattens colors and creates harsh shadows.

For winter photography, bring warm gloves and a lens cloth—moisture from breath can fog glass.

Is It Worth Visiting Outside Autumn?

Yes, but with caveats. In summer, the forest is a cool green retreat with wildflowers at the edges. The glacier views are still dramatic.

However, the signature “Flame of the Plateau” effect is absent. If you are in Siguniang for climbing or trekking, a stop at the forest is convenient since it’s the bus terminus. Winter offers a serene, almost monochrome landscape—lovely for those who enjoy stark beauty, but the trees are bare and trails may be icy.

Frequently Asked Questions

What is the altitude of the Red Sequoia Forest?
Approximately 3,840 meters (12,598 feet) above sea level. This is the highest stop on the Shuangqiao Valley bus route.

Do I need to hike to get there?
No. The scenic area’s sightseeing bus drives directly to the forest, which is the last stop. From the bus drop-off, wooden boardwalks lead into the forest.

What is the best time to see the red leaves?
Typically mid-to-late October to early November, when the sequoia needles turn golden and red. Exact timing varies by year.

Is there a risk of altitude sickness?
Yes. At 3,840 meters, the air is thinner than at lower valley points. Walk slowly, avoid running, and consider portable oxygen if you are not acclimatized.

Can I see glaciers from here?
Yes. The forest sits at the base of Jade Hare Peak and Hunter Peak, where hanging glaciers are visible. In summer, meltwater waterfalls are also present.

Do I need a permit?
No special permit is required beyond the standard Siguniang Mountain scenic area ticket. However, travel to Aba prefecture may require a foreigner travel permit (Sichuan border area rules); check with your tour operator.

How long should I spend here?
Most visitors allocate 2–3 hours, including bus rides and walking the boardwalks.

Is it crowded?
Midday in autumn and summer holidays can be busy. Early morning or late afternoon offer more solitude.

Plan Your Visit

Red Sequoia Forest is part of the Shuangqiao Valley scenic area, which is the most accessible of Siguniang’s three valleys (Changping and Haizi require more hiking). The valley entrance is in Rilong town, about 4 hours by car from Chengdu. The best strategy is to stay overnight in Rilong to acclimate to altitude (around 3,200m). The next morning, take the first bus to enjoy the forest before the crowds.

What to bring: Warm layers (temperatures drop rapidly), sunscreen, sunglasses, rain jacket (afternoons can bring showers), water, snacks, and any altitude medication you use.

What not to bring: Heavy backpacks are unnecessary—boardwalks are easy. Drones are not allowed inside the scenic area (unless special permit; check current rules).
