About This Trail

The Changping–Bipeng Traverse (长穿毕) is one of China's 'Ten Classic Trekking Routes,' a 37km point-to-point journey through the Mount Siguniang massif in western Sichuan. Over three days, the route transitions from ancient conifer forests and turquoise streams to vast alpine meadows carpeted with rhododendrons, culminating in a pre-dawn ascent of the 4,668m Kaza Pass (叉子沟垭口) where 360° panoramic views reveal the four peaks of Siguniang — including the 6,250m 'Queen of Sichuan's Peaks' (幺妹峰). The descent into Bipeng Valley reveals glacial lakes and, in autumn, some of China's most spectacular fall foliage. The route's staircase-like elevation gain (3,200m → 3,760m → 3,900m → 4,668m) provides natural acclimatization, making it the 'graduation test' for aspiring high-altitude trekkers.

Trail Highlights

  • Kaza Pass at 4,668m — 360° views of the four Siguniang peaks and sea of clouds
  • Direct view of the 6,250m Yaomei Feng ('Queen of Sichuan's Peaks') from Mulezi Camp
  • Dead Tree Beach — skeletal trunks standing in emerald pools with snow peak reflections
  • Staircase acclimatization design — natural altitude progression over 3 days
  • Bipeng Valley's glacial lakes and legendary autumn foliage (Sep-Oct)
  • UNESCO World Heritage — part of the Sichuan Giant Panda Sanctuaries

Difficulty

Moderate to challenging. Days 1-2 are gentle to moderate (5-8 hours, gradual elevation gain on good trails). Day 3 is the crux: a pre-dawn start at 2-3 AM, 800m steep ascent on loose scree to the 4,668m pass, followed by a hazardous 1,000m descent on loose rock. The pass is the most dangerous section — crampons essential if snow is present. Pack animals cannot cross the pass on Day 3, so you must carry your own pack (12kg limit) or hire a porter (¥300-350/bag). Altitude sickness is a real risk above 4,000m.

Recommended Itineraries

Classic 3-Day Traverse

⏱ 3 days / 2 nights
+

The standard Changping–Bipeng Traverse — the route that earned its place among China's top ten treks.

4-Day with Acclimatization (Recommended for Foreigners)

⏱ 4 days / 3 nights
+

Add a night in Siguniang Town (3,200m) for altitude acclimatization before starting the traverse — strongly recommended for those coming from sea level.

Changping Valley Round Trip (No Pass Crossing)

⏱ 2 days / 1 night
+

Hike into Changping Valley to Mulezi Camp and return the same way — avoids the challenging pass crossing. Ideal when the traverse is closed or for those not ready for the 4,668m pass.

Detailed Gear List

  • Waterproof hiking boots with ankle support and good grip — stream crossings, mud, and loose scree on the pass
  • 4-season tent and sleeping bag rated to -10°C — night temperatures at 3,900m can drop below freezing even in summer
  • Insulated sleeping pad (R-value 4+) — cold ground at 3,760-3,900m
  • Crampons/microspikes — MANDATORY April-June; pass snow can be deep and icy
  • Gore-Tex hard shell jacket — weather above 4,000m changes in minutes from sun to blizzard
  • Trekking poles — essential for the steep pass ascent and dangerous scree descent
  • SPF50+ sunscreen, UV-blocking sunglasses, and wide-brim hat — extreme UV at 4,000m+
  • Headlamp with spare batteries — 2-3 AM departure on Day 3; some sections have no natural light
  • Waterproof stuff sacks and pack cover — rain is common in the afternoons
  • Diamox (acetazolamide) — consult your doctor before the trip for altitude sickness prevention
  • Warm layers: fleece mid-layer + down jacket — pass temperature can be near 0°C with wind chill
  • Power bank — cold drains batteries fast; no charging at camps

Best Season

🗓

Best: May-June (rhododendron bloom, snow-melt streams, possible residual snow on pass requiring crampons) and September-October (clear skies, spectacular fall foliage in Bipeng Valley, golden meadows). July-August is the rainy season — heavy rain, landslides, leeches, and cloud-obscured peaks make it the least desirable time. Winter (November-April): the traverse is CLOSED — the scenic area prohibits overnight outdoor activities. The outdoor season runs approximately April 10 to October 31 each year.

Safety Notes

  • ⚠️ Altitude sickness is the primary risk — spend at least one night at 3,200m (Siguniang Town) before starting; if symptoms (severe headache, nausea, dizziness) persist, descend immediately — this is the only effective treatment
  • ⚠️ Kaza Pass is the most dangerous section — loose scree on steep slopes, sudden weather changes from clear to blizzard, and risk of hypothermia from long waits at altitude
  • ⚠️ Day 3 pack animals cannot cross the pass — you must carry your own gear (12kg limit) or hire a porter (¥300-350/bag, book in advance)
  • ⚠️ Mobile signal is essentially zero on 90% of the route — download offline maps and inform contacts of your planned exit time
  • ⚠️ Reverse traversal (Bipeng → Changping) is PROHIBITED and extremely dangerous — a hiker died in October 2025 attempting a reverse traverse; violators face ¥100-5,000 fines and lifetime bans
  • ⚠️ Start the pass crossing early (2-3 AM) — afternoon weather deteriorates rapidly; late starters risk getting caught in storms at 4,668m
  • ⚠️ Emergency evacuation is extremely limited — helicopter rescue is rarely available; evacuation by horse or stretcher may take 24+ hours
  • ⚠️ Strictly no open fires — use only gas canister stoves at designated campsites

Book 1-2 weeks ahead in peak season (Sep-Oct, May-Jun). NOTE: As of July 2026, the full traverse route has NOT fully reopened — confirm with Siguniang Mountain Management (400-688-6250) or a reliable agency before booking.

💳

🚌

Getting There

Chengdu → Siguniang Town: Bus from Chadianzi Station (4-5h, ¥95-120), shared car (3.5-4h, ¥120-150/person), or self-drive via Rongchang Expressway → Yingxiu → Wolong → Balang Mountain tunnel. NOTE: Balang Mountain tunnel may have ice restrictions in winter; holidays often cause Chengdu-Yingxiu congestion. From Bipeng Valley exit: Lixian → Chengdu by bus or private car (3-4h). Since this is a point-to-point trek, arrange vehicle transfer or use commercial group transport.

🏨

Accommodation

Siguniang Town (3,200m): numerous guesthouses ¥120-450/night; some offer oxygen equipment and mountain-view terraces. Mulezi Camp (3,760m): wooden shelter with hot water, pit toilets, small shop — bring your own tent or use commercial group camping setup. Chazigouwei Camp (3,900m): basic wooden shelter, pit toilets only, no hot water guarantee. Cold and basic — sleeping bag essential. Post-trek: Lixian town hotels from ¥150/night.

🗣️

Language

Local guides speak almost ZERO English — this is the single biggest barrier for foreign trekkers. Contact us to arrange an English-speaking group leader for your trek, or bring a translation app with offline Chinese-English capability. Useful phrases: 垭口 (yà kǒu) = mountain pass; 向导 (xiàng dǎo) = guide; 高反 (gāo fǎn) = altitude sickness; 背夫 (bèi fū) = porter; 木骡子 (mù lí zi) = Mulezi camp

📶

Connectivity

Mobile signal at Mulezi Camp (weak) and Chazigouwei shelter (very weak). ZERO signal on 90% of the trail and at the pass. No WiFi at camps. Download all offline maps (Gaode/Amap recommended) and inform contacts of your 3-day itinerary before departure. Satellite communicators (Garmin inReach) are advisable — available for rent from Chengdu outdoor shops.

🚨

Emergency

Siguniang Town Health Center: 0837-2791120. Rilong Town Hospital: limited high-altitude capability. Nearest major hospital: Chengdu (3.5-4h away). Ambulance: 120, but response to remote trail locations takes hours. Helicopter rescue: extremely limited and expensive. Your guide should carry emergency communication. Altitude sickness: descend immediately if symptoms worsen — Diamox can help prevent but not cure AMS.

💡 Insider Tip: If the full traverse is closed (as of July 2026 it has not fully reopened), the round-trip to Mulezi Camp is an excellent alternative — you get 80% of the scenery with 20% of the difficulty. The sunrise 'Golden Mountain' light on Yaomei Feng from Mulezi is one of China's most photographed mountain moments. And whatever you do, NEVER attempt a reverse traverse — it's not just illegal, it's genuinely life-threatening.

The pass at dawn was transcendent — the four peaks glowing gold above a sea of clouds. Day 3 is brutal but the reward is unmatched. This is the trek that made me fall in love with China's mountains.

★★★★☆

Beautiful but underestimated the pass. Started at 2 AM in snow, reached the top by 7 AM. The descent on loose scree was scarier than the climb. Crampons were absolutely essential — several people turned back without them.
