Changping–Bipeng Traverse

4 days across Mt Siguniang — autumn larches, mirror lakes, the 4,668 m pass

Duration 4 days
Difficulty moderate
Max altitude 4,668 m
Best season May – Jul · Sep – Oct

Mount Siguniang (四姑娘山 / Skara Tagphu) is a 6,250 m massif west of Chengdu — four pyramidal peaks rising over a Tibetan plateau edge. The classic 4-day traverse threads two of its valleys: Changping (the autumn-larch + Tibetan-stupa valley on the south side) and Bipeng (the alpine-lake + reflection valley on the north). The 4,668 m Muluozi Pass (also spelled Mu Luozi or Mu Niu Tzu) connects them. Permit-mandatory, guide-led, and one of the most photogenic moderate treks in Sichuan.

The experience

  • Chengdu → Rilong (the Siguniang gateway town) on Day 1 — ~4 hrs drive
  • Days 2-3 trekChangping Valley → Muluozi Pass (4,668 m) → Bipeng Valley descent — 2 nights camping at ~3,800 m and ~3,500 m
  • Pack-horse support for camping gear; you carry day-pack only
  • Permit-mandatory and licensed Tibetan guide bundled into the trip price — non-negotiable for foreign trekkers
  • Day 4 exit via the Wenchuan corridor → return to Chengdu by late afternoon

Why the traverse, not a one-valley hike

  • Changping Valley alone (south side) is a popular day-hike + camping option — accessible from Rilong, well-marked, suitable for any reasonably fit walker. Bipeng Valley alone (north side) has a famous Friday morning shuttle-bus boardwalk that lets day visitors cover the iconic mirror-lake viewpoints. Both are good. Neither is the trip.
  • The traverse links them. You walk up Changping's autumn-larch corridor past the Tibetan stupa, climb to the Muluozi Pass between them, drop into Bipeng's alpine lakes — and end with a sense of crossing one mountain rather than visiting two scenic spots.
  • Difficulty is moderateno technical climbing, but Day 3 is a 1,000 m gain to a 4,668 m pass, and the descent into Bipeng is long on knees. Strong recreational hikers handle it comfortably with proper acclimatisation.

Day 1 — Chengdu → Rilong (3,200 m)

  • Morning departure from Chengdu — private vehicle climbs west on the G4217 expressway, then up the Min River valley toward Lixian and on to Rilong, the Siguniang gateway town (~4 hrs with photo stops).
  • Afternoon at Rilonggear check at the trekking outfitter, permit collection with the licensed Tibetan guide, easy ridge walk to the Shuangqiao Valley viewpoint for first sight of the four-sisters peaks at sunset.
  • Tibetan-style boutique inn for the night. Early dinner, dry-pack the next morning's day-pack, alarm set for 06:30.

Day 2 — Changping Valley to high camp

  • Morning entry to Changping Valley via the park shuttle. Trek-in past the Lama Temple ruins, the Tibetan stupa at the valley mouth, and the autumn-larch boardwalk — ~12 km, ~6-7 hrs walking, gentle gradient up to ~3,800 m.
  • Camp at the valley head meadow. Pack-horses arrive by mid-afternoon with the camping gear; you've been carrying day-pack only.
  • Late-afternoon light on the Muluozi Pass headwall — your route up tomorrow. Camp dinner (Sichuan-style hot stew adapted for altitude), tent reset, alarm 05:30 for the pass-day start.

Day 3 — Muluozi Pass (4,668 m) → Bipeng descent

  • The trip's big day. 05:30 alarm, 06:30 departure. Headlamps until first light. ~1,000 m gain to the Muluozi Pass (4,668 m) — rocky scree-slope ramp, no technical sections but sustained altitude.
  • Top of the pass by mid-morningprayer flags, the views back across Changping and forward into Bipeng. Roughly 30 minutes for photos and a hot drink, then the long descent.
  • Descent into Bipeng~6 hours, ~1,100 m drop through alpine meadow, then into the larch and rhododendron belt. Two main viewpoints en route — Panyang Lake and the Bipeng upper mirror lake.
  • Camp at the Bipeng valley head meadow (~3,500 m). Hot meal, hot drinks, deeply earned sleep.

Day 4 — Bipeng Valley exit → Chengdu

  • Slow morning at the camp — Bipeng's morning mist over the mirror lake is the trip's quiet farewell shot.
  • Trek out via the Bipeng park boardwalk to the valley entrance — ~10 km, gentle downhill, ~4 hrs walking.
  • Park shuttle to the road head; transfer south via the Wenchuan corridor back to Chengdu (~3.5 hrs).
  • Drop-off at your Chengdu hotel by late afternoon. We recommend a buffer night in Chengdu before any onward flights — knees need rest, jet-lag and altitude don't combine well on the same travel day.

Practical details
  • Fitnessmoderate to challenging. Comfortable with 6-7 hrs of hiking per day for three consecutive days; Day 3 is the hardest single day (1,000 m gain to 4,668 m, then 1,100 m descent).
  • Altitudesleeps at 3,200 m → 3,800 m → 3,500 m. The pass tops at 4,668 m for ~30 mins. Acclimatisation: we strongly recommend a Chengdu arrival night (sea-level) but add a Wolong Panda Centre detour at 2,000 m on the Day 1 drive if your group includes anyone altitude-sensitive.
  • Permit + guidemandatory and non-negotiable for foreign trekkers. We arrange both 4+ weeks ahead. The licensed Tibetan guide handles route-finding, weather decisions, and emergency call-out protocols.
  • Best windowslate May to early July (rhododendron bloom + snowmelt + wildflowers); late September to early October (autumn larch + clear post-monsoon skies). Avoid late October onwards (snow accumulating on the pass; Bipeng overnight trekking closes by mid-November) and July-August monsoon (heavy mud + leech risk in the forest sections).
  • Group size4-8 trekkers. Pack-horse handlers + permit logistics scale up cleanly within that range.
  • Pricingfrom AUD $2,400 pp twin-share for the standalone 4-day module — includes Tibetan guide, permit, pack-horse support, camping gear, all meals on trek + Rilong hotel + Chengdu transfers. Excludes international flights, AMS-evac insurance (mandatory).
Common questions

Before you book

01 How is this different from your existing Siguniang & Bipeng Valley itinerary?

The itinerary (`/itinerary/siguniang-bipeng-valley-tour/`) is a 4-day private DRIVING tour — you sleep in lodges at Rilong + the Bipeng entrance, day-walk into each valley on the park boardwalks, and don't cross the pass. It's the right choice for travellers who want the scenery without the camping or the high-altitude effort. This traverse is the full multi-day TREK with two nights under canvas and a 4,668 m pass crossing. Different product, different audience — the itinerary suits ~60% of travellers; this traverse suits the other 40%.

02 How hard is the pass day really?

Day 3 is the trip's hardest single day, but it's not technical. 1,000 m gain on a rocky scree-ramp to 4,668 m, then 1,100 m descent into Bipeng. Total ~12-14 hrs from breakfast to dinner with breaks. Most strong recreational hikers (people comfortable with 7+ hr days in mountainous terrain) handle it fine if they're acclimatised. The biggest enemy is altitude underestimation — the pass is the height of Mt Blanc's base; come prepared.

03 What about the season — can I do it in winter?

No. Overnight trekking + camping in Changping and Bipeng closes from mid-November to late April by park regulation — snow accumulation on the pass + temperatures dropping below -20°C at night make it unsafe. The park is open to day visitors year-round but the traverse specifically requires the May-October window. May-June for wildflowers, late September to early October for autumn colour.

04 Can we combine this with pandas or West Sichuan?

Yes. Standard combinations: (a) 1-day Wolong Panda Centre add-on on the Day 1 drive (acclimatisation bonus at 2,000 m + a kid-friendly stop); (b) extend into the West Sichuan Tour on Day 4 — drop off at Litang or Daocheng instead of returning to Chengdu, continue into the Tibetan plateau for another 5-7 days; (c) end with a Chengdu food-day before flying out (we run the Chongqing & Chengdu itinerary for this). Talk to us about combinations.
