Western Sichuan Loop Travel Guide 2026: Small Circuit, Big Circuit & How to Actually Do It
Western Sichuan is China's most concentrated dose of Tibet — four days of driving from Chengdu buys you 7,500-meter snow peaks, thousand-year-old watchtower villages, grassland monasteries and the "photographer's corridor" of Xinduqiao, without Tibet's permits. This guide covers the two classic loops: the 5-day Small Circuit (Siguniang, Danba, Moshi Park, Tagong, Xinduqiao) and the 9-11 day Big Circuit adding Litang and Daocheng Yading. It also answers the questions that decide everything for foreign travelers: why you cannot legally drive yourself (IDPs are invalid in China — the charter-with-driver alternative explained), why Seda's Larung Gar is currently closed to foreign passport holders (and what to see instead), how the new Zheduoshan Tunnel changed the route, and the altitude-staircase logic that keeps altitude sickness manageable.

Why Western Sichuan Is China's Best Road Trip
Tibet-level landscapes without Tibet-level paperwork — the densest scenic driving in Asia
Western Sichuan (川西) is the eastern edge of the Tibetan Plateau, and it delivers nearly everything travelers imagine about Tibet — snow peaks over 7,000 meters, grasslands dotted with yaks and monasteries, red-robed monks, prayer flags strung across passes — with two decisive advantages: no Tibet Travel Permit (foreigners travel freely with just a passport) and a five-hour drive from a major international hub with Sichuan food at both ends. The scenic density is unmatched: on the Small Circuit alone, a single day's drive crosses a 5,000-meter-class mountain, a geological "alien planet" stone forest, and a grassland temple.
No Permits, No Guides Required
Unlike Tibet, foreigners need no travel permit, no arranged tour and no mandatory guide for the western Sichuan loops. A passport buys entry at every stop on both circuits — with one significant exception (Seda), covered separately below.
The Altitude Staircase
The route climbs gently: Chengdu (500 m) → Siguniang town (3,200 m) → Danba (1,800 m, sleep low) → Xinduqiao (3,300 m) → Litang (4,000 m). The natural up-down rhythm is acclimatization built into the road — far kinder than flying into Lhasa.
2026 Is the Best Year Yet
The Zheduoshan Tunnel is open (no more crossing the 4,298 m pass), G350 Panda Avenue and S434 are fully paved, and the G227 to Litang lifted traffic controls in June. Sedans now run the Small Circuit comfortably — unthinkable a few years ago.
Four Seasons of Photography
July-August greens the grasslands with wildflowers; late October turns Xinduqiao's poplar corridor gold; winter delivers the clearest snow-peak views of the year. The loop rewards every season differently — and re-visits.
Small or Big? First-timers with 4-6 days: the Small Circuit — it concentrates snow peaks, Tibetan villages and grasslands with gentle altitude. Travelers with 9-11 days who want the full plateau pilgrimage: the Big Circuit, adding Litang (4,000 m, "the city in the sky") and Daocheng Yading's three sacred peaks. Both start and end in Chengdu, and both can be done with a chartered car and driver — the recommended way for foreign visitors.
The Small Circuit: 5 Days, 880 km, Zero Regrets
Chengdu → Siguniang → Danba → Moshi Park → Tagong → Xinduqiao → Kangding → Chengdu
The Small Circuit (小环线) is the classic western Sichuan loop: roughly 880-1,100 km of fully paved road, doable in a regular sedan, packing four completely different landscapes into five days. The 2026 route logic has one new rule — the Zheduoshan Tunnel bypasses the old 4,298 m pass — and one proven rhythm: start each driving day before 6:30 AM, finish driving by 16:00, and let the afternoons belong to the views.
Chengdu → Siguniang Town
G350 Panda Avenue via Yingxiu and Wolong (175 km, ~3 h plus stops). Pause at Balang Mountain's viewpoints; photograph the four sisters from Maobiliang (free). Afternoon: Shuangqiao Valley by sightseeing bus (ticket ¥80 + shuttle ¥70) — zero hiking, full snow-mountain immersion. Sleep at 3,200 m — mild altitude, first acclimatization night.
Siguniang → Danba
Descend to the Dadu River valley (3 h). Danba sits at 1,800 m — the loop's "sleep low" night, ideal for recovery. Afternoon: Jiaju Tibetan Village (¥50) — hundreds of white-walled watchtower houses stacked across the hillside, one of China's officially "most beautiful villages." Stay in a village guesthouse (¥80/person with carved wooden interiors) or town hotel.
Danba → Moshi Park → Tagong → Xinduqiao
The single most varied driving day: morning at Moshi Park's grey-black mylonite stone forest (¥60 + optional ¥20 shuttle — "alien planet" geology), midday across Tagong Grassland (cleanliness fee ~¥15-35; Tagong Temple ¥20; the golden Muya Chorten free outside), sunset option at Yuzixi viewpoint (cleanliness fee ¥30-50) for the 360-degree Gongga panorama. Sleep Xinduqiao at 3,300 m.
Xinduqiao → Kangding
Morning light along the Ten-Mile Corridor (free — poplars, streams, Tibetan houses, the reason this town is called the "photographer's corridor"). Drive S434 past Honghaizi (free lake) and Mugecuo scenic area; cross via the new Zheduoshan Tunnel (no more 4,298 m pass) or detour the old pass for photos. Sleep Kangding (2,560 m) — hot springs and city comforts.
Kangding → Chengdu
Return via the Yakang Expressway (3-3.5 h), optionally pairing with the Dujiangyan panda base or Wolong on the way in. Budget-conscious travelers: the same loop compresses to 4 days by merging Days 1-2; luxury travelers add a second Xinduqiao day for photography at dawn and dusk.
Small Circuit budget (per person, 4 sharing a chartered car): ¥1,200-1,900 excluding flights — car ¥800-1,200/day split four ways, hotels ¥150-400/night, tickets under ¥350 total, meals ¥60-100/day. Peak-season (July-September) hotel prices rise 25-35%; book one month ahead.
The Big Circuit: 9-11 Days to Litang & Yading
Everything in the Small Circuit plus the "sky city," sacred peaks and the world's highest town
The Big Circuit (大环线) extends the loop south and west along the G318 — China's fabled "highway above the clouds" — adding Litang (4,014 m, the highest town in the world by some measures), the Daocheng Yading park with its three 6,000-meter sacred peaks, and optionally the Xinlong or Ganzi highland routes. Total distance reaches 1,700+ km; altitude averages above 3,500 m for days at a time; and the reward is the deepest immersion into Kham Tibetan culture available without a Tibet permit.
Chengdu → Siguniang → Danba → Xinduqiao
Run the Small Circuit's first half as your acclimatization phase (see above for details). The critical difference: pace slower. Three nights of progressive sleeping altitude (3,200 → 1,800 → 3,300 m) pre-loads your body for the 4,000+ m week ahead.
Xinduqiao → Litang → Daocheng
Cross the G318's famous high passes (Jianziwan's hairpins, Kazila at 4,718 m). Litang (4,014 m): the Litang Chode Monastery, the Letong Ancient Town thousand-household village (¥100 combined ticket) and the grassland where the 7th Dalai Lama was born. Continue to Daocheng (3,750 m) or press on to Shangri-La Town (2,900 m — the smart, lower sleep).
Daocheng Yading — Two Days
Day one: the short line (Chonggu Monastery → Pearl Lake, ~4 h, gentle). Day two: the long line at dawn (Luorong Pasture → Milk Lake → Five-Color Lake, 6-8 h to 4,700 m) — the most demanding mainstream hike in Chinese tourism and the Big Circuit's crowning day. Park entry ¥146 (peak) + mandatory bus ¥120; check the 2026 free-entry window (Aug 1-Oct 31) before booking.
Return Legs
Retrace via Litang or loop north through Ganzi and Maerkang (adds Seda-adjacent grasslands and the Guozhuang watchtower country); overnight Xinduqiao or Kangding; final day back to Chengdu. Or skip the drive out: Daocheng Yading Airport (4,411 m — the world's highest civil airport) flies to Chengdu in 65 minutes.
Driving Rules for Foreigners: The Legal Reality
Why your IDP doesn't work here — and the two documents that do
This is the part most guidebooks bury, and it matters more in western Sichuan than anywhere else in China. The rule: International Driving Permits and foreign licenses are not valid in mainland China. China never signed the 1949 Geneva or 1968 Vienna road conventions, so an IDP confers zero driving rights — driving on one is legally unlicensed driving, voiding your insurance and risking fines, vehicle impoundment and detention. No exceptions for any nationality.
| Option | What It Is | Validity | Practical Verdict for Western Sichuan |
|---|---|---|---|
| Foreign license + IDP | Not recognized in mainland China | None | Illegal to drive on — do not attempt |
| Temporary Driving Permit | Issued at Vehicle Administration Offices in Chengdu; needs passport, visa, home license + certified translation, photo | Up to 90 days (tourist visa) | Legal, but 1-5 business days + a ¥560 certified translation — viable for long trips |
| Full Chinese license | Theory test (100 questions, pass 90) for license-holders | 6 years | For residents only |
| Charter car with driver | 7-seat van + professional driver through a licensed operator | Per trip | The standard choice — and the one this guide recommends |
Why charter beats self-drive here specifically: beyond the license hurdle, western Sichuan roads involve 4,000 m passes, monsoon-season rockfall zones, yak right-of-way, police checkpoints and signal dead zones. A local driver who runs the loop weekly handles all of this while you watch the scenery — and the car carries the commercial insurance that covers it. If you do obtain a Temporary Permit and self-drive: SUV (¥350-700/day), chains aboard even in summer, refuel below one-third tank, offline maps, and never drive the cliff roads after rain.
Chartering a Car with Driver: How It Works
Costs, vehicle classes, what to verify, and the questions that separate good operators from bad
The Numbers (2026)
Standard 7-seat business van (Buick GL8 class) with driver: ¥800-1,200/day including fuel and driver's board — split four to six ways, ¥150-300/person/day. Premium SUV with driver runs ¥1,000-1,500/day. Prices peak 25-35% in July-September and Golden Week.
What to Verify Before Paying
Three documents: the vehicle's road transport permit (道路运输证), carrier liability insurance (承运人责任险), and the driver's highland driving experience. Legitimate operators produce all three on request. Also confirm whether tickets, hotels and meals are included or separate — "all-inclusive" quotes vary wildly in what they include.
The Driver Bonus
Good loop drivers are half-guides: they know which bend hides the Gongga view, which teahouse in Litang serves the real butter tea, where the yaks cross at dusk, and how to read the monsoon clouds. They also handle police checkpoint registration — a real convenience for foreign passport holders.
Booking Channels
International platforms (Trip.com, Klook, GetYourGuide) list vetted charter products with English support — the safest route for first-time visitors. Direct Chinese platforms (Ctrip domestic, Fliggy) offer more choice at lower prices but demand Chinese-language negotiation. Custom travel designers (like us) build the full itinerary around your pace and interests.
Seda's Larung Gar: The 2026 Reality for Foreign Visitors
The red-house monastery is currently mainland-ID-only — here's the honest picture and the alternatives
Seda's Larung Gar (色达五明佛学院) — the vast red-roofed monastery city spilling over a mountain valley, one of the most photographed places in Tibet — requires honest treatment in any 2026 guide: entry is currently restricted to holders of mainland Chinese resident ID cards. Foreign passport holders, including Hong Kong, Macau and Taiwan travelers, cannot book through the official "Larung Valley Entry Reservation" mini-program or enter through any local-assisted channel. The policy has no announced end date.
The System for Chinese ID Holders
Daily cap ~3,000 visitors; reservations open at 18:00 for the day three days ahead via WeChat mini-program; ¥200 refundable deposit; 90-minute visit limit; shuttle ¥30 round trip from Luoruo Town. Tickets vanish within minutes in peak season — even locals set 17:55 alarms.
What Foreigners Can Still Do
The surrounding Seda county is fully open: Donggar Monastery (free, with interiors worth half a day), the Jinma Grassland (free), the Gesar Culture and Art Center (free), and Wengda Tibetan village (free). The drive itself — high plateau grasslands with herds and nomad camps — remains one of the region's great roads. What you cannot do is enter the Larung valley itself.
The Planning Verdict
If Seda was your primary goal: check current policy with your operator before committing (rules have shifted before), and design the itinerary so its removal costs nothing — the Dege/Ganzi/Manigango route offers monastery-and-landscape intensity of similar depth. If Seda is closed, redirect those two days to Yading's long line and the Litang grasslands.
Ignore anyone selling "local guide takes you in" schemes. All reporting in 2026 confirms no back channel exists for foreign ID holders, and attempts simply strand you at the checkpoint. The honest operators will tell you this upfront — treat it as a credibility test when choosing your travel company.
The Altitude Plan: Sleeping Logic for the Loops
Where you sleep matters more than where you drive — design the nights, and the days take care of themselves
| Night Stop | Altitude | Role in the Acclimatization Plan |
|---|---|---|
| Chengdu | 500 m | Sea-level baseline; last hotpot, full oxygen |
| Siguniang town | 3,200 m | First altitude night — mild, valley-protected |
| Danba | 1,800 m | The recovery night — sleep low while your body builds red cells |
| Xinduqiao | 3,300 m | Consolidation night; hotels with oxygen available |
| Litang | 4,014 m | The test — only sleep here if the week went smoothly |
| Shangri-La Town (Daocheng) | 2,900 m | The smart base for Yading — sleep low, hike high |
| Kangding | 2,560 m | Descent night with hot springs and city comforts |
The three rules that prevent 90% of altitude sickness here: ascend gradually (the loops do this naturally — never skip the Danba low night to "save time"); hydrate relentlessly (3-4 liters daily; the plateau air steals water invisibly); and never sleep more than 500 m above the previous night when past 3,000 m. Diamox 125 mg twice daily starting the night before ascent is the evidence-backed pharmacological option — consult your doctor before the trip. Mild headache on day one is normal adaptation, not a crisis; worsening symptoms at rest mean descend.
2026 Road Update: What Changed This Year
Tunnels, paving and controls — the current state of every major road
Zheduoshan Tunnel: Open
The biggest single upgrade: traffic now bores through the mountain instead of crossing the 4,298 m Zheduoshan pass — safer, faster, weather-proof. The old pass road remains open for photographers willing to add an hour for the classic switchback view.
Fully Paved Trunk Roads
G350 Panda Avenue, S434, S248 and the G318/G227 trunk network are now completely asphalt — a normal two-wheel-drive sedan handles the standard Small Circuit without stress. Verified by multiple 2026 test runs.
G227 Litang-Yading Controls Lifted
The Liya road's construction controls ended June 8, 2026 — the pavement to the Daocheng Yading direction is complete and unrestricted. The Big Circuit's southern leg is now the smoothest it has ever been.
Monsoon-Season Caution (Jun-Aug)
Every summer, cliff-side segments see rockfall and occasional landslides; the Lixiao road and Genie south line stay off-limits to regular vehicles. Rule of thumb: stick to numbered trunk roads (G318, G350, S434), finish driving by 16:00 in the rain season, and never take unpaved "shortcuts" a map app suggests.
The Key Stops: What Each One Actually Delivers
A rapid-fire guide to the loops' essential waypoints
Siguniang Mountain
Four peaks, three valleys (see our dedicated snow mountain guide). Shuangqiao Valley is the bus-and-viewpoint option; Changping adds trekking; Maobiliang gives the free panorama. The 2026 three-valley combo ticket runs ¥150.
Danba & Jiaju Village
Watchtower-and-whitewash architecture stacked up valley walls; Jiaju's ¥50 entry includes the viewpoint road. Add the Zhonglu and Badi villages for thinner crowds, and the Suopo watchtower cluster for the oldest towers.
Moshi Park
Grey-black mylonite stone forest that looks photoshopped — "the most alien landscape within driving distance of a major city." ¥60 + ¥20 shuttle; enter from the back gate to skip queues. One to two hours suffices.
Tagong Grassland & Temple
Grassland cleanliness fee ~¥15-35, Tagong Temple ¥20 (the "little Jokhang"), the golden Muya Chorten free to photograph. Yaks, monks and the Yala sacred peak in one frame — the Kham postcard.
Xinduqiao
The "photographer's corridor": 15 km of poplars, streams and Tibetan houses along the G248, free and endlessly shootable. Golden hour here — and the Yuzixi star-gazing platforms nearby — justify the town's hotel boom.
Litang
At 4,014 m, the "city in the sky": Litang Chode Monastery, Letong Ancient Town's thousand-household village (¥100 combined), and the birthplace grassland of the 7th Dalai Lama. Arrive acclimatized; move slowly; the light is extraordinary.
Ticket Summary: What Everything Costs (2026)
Every stop on both loops, priced and prioritized
| Site | Entry | Extras | Worth It? |
|---|---|---|---|
| Siguniang Shuangqiao Valley | ¥80 | Shuttle ¥70 mandatory | Essential — snow peaks without hiking |
| Siguniang 3-valley combo | ¥150 | Valid to Dec 31, 2026 | Best value if visiting two+ valleys |
| Jiaju Tibetan Village (Danba) | ¥50 | Viewpoint road included | Essential — architecture + culture |
| Moshi Park | ¥60 | Shuttle ¥20 optional | Worth it — unique geology |
| Tagong Grassland | ~¥15-35 fee | Temple ¥20 | Essential — the Kham postcard |
| Yuzixi viewpoint | ¥30-50 fee | Sunset/star platform | Worth it for photographers |
| Xinduqiao corridor | Free | — | Essential — costs nothing |
| Honghaizi lake (S434) | Free | — | Quick stop en route |
| Litang Letong Town | ¥100 | Combined ticket | Worth it with a guide's context |
| Daocheng Yading (peak) | ¥146 | Bus ¥120; cart ¥80 | The Big Circuit's pinnacle |
Booking rules: reserve 3-5 days ahead on official mini-programs for Siguniang and Yading (peak season sells out); most other stops sell on-site or at the gate with a passport. The Ganzi "Begonia Card" (¥317) grants lifetime entry to 14 regional sights — worthwhile only for repeat visitors. Students and 60+ travelers carry discounts nearly everywhere with ID.
When to Drive the Loops: Season by Season
Each season changes the loops' personality — pick the one matching your photos
| Season | Landscape | Conditions | Verdict |
|---|---|---|---|
| Spring (Mar-May) | Azaleas on the passes, snow still on the peaks | Cold nights, occasional late snow at altitude | Quiet, crisp, half-empty roads |
| Summer (Jul-Aug) | Green grasslands, wildflowers, full rivers | Monsoon afternoons; rockfall risk on cliff roads | Peak season — book ahead, drive mornings |
| Autumn (Sep-Oct) | Xinduqiao poplars gold, crystal visibility | Stable, cool, perfect light | The photographer's season — and the busiest |
| Winter (Nov-Feb) | Snow-draped everything, unmatched clarity | Icy passes, chains required, short days | For experienced parties only — sublime rewards |
The sweet spots: mid-June (green season before the July crowds) and mid-to-late October (peak foliage after the Golden Week exodus). Either delivers the loops' best version with manageable company on the roads.
Packing for the Loops: The All-Seasons Kit
One bag that handles 25°C valleys and -10°C passes in the same day
The Layer System
Base layer (synthetic, never cotton), fleece mid-layer, windproof shell, and a light down jacket even in July — passes run 15°C colder than valleys, and Yading's 4,700 m lakes sit near freezing year-round. The 15°C+ day-night swing is the loop's only constant.
Sun & Health
SPF50+ sunscreen, UV sunglasses, lip balm, wide-brim hat — at 4,000 m you receive roughly 40% more UV than at sea level. Personal meds, Diamox if prescribed, motion-sickness tablets (the passes switchback relentlessly), and 3-4 L water daily.
The Road Kit
Offline maps downloaded (signal dies on the passes), power bank (cold kills batteries), thermos (free hot water everywhere), snacks, and small bills for grassland fees and temple offerings. If self-driving: chains, torch, and the one-third-tank refuel rule.
Cultural Extras
Shoulder-covering layer for monastery visits (scarves work), slip-on shoes for temple interiors, and modest shorts-free options for Litang's monastic settings. A small gift budget for the craft workshops in Danba's villages supports the communities hosting you.
Where to Sleep: The Hotel Logic
Altitude, oxygen and hot water — the three questions for every booking
The Standards Ladder
Siguniang town and Xinduqiao now offer genuine comfort: oxygen-enriched rooms, heated floors and reliable hot water in the ¥300-600 range. Danba's village guesthouses (¥80-150) trade polish for authenticity — carved wooden interiors and host-family dinners. Litang's best remain functional at 4,000 m; manage expectations accordingly.
The Oxygen Question
Ask every hotel above 3,000 m two things: does the room have oxygen (either piped or concentrator rental, ¥50-100/night)? and does the hot water run at 21:00 peak? The answers separate the plateau-ready hotels from the ones that merely photograph well.
Booking Timing
One month ahead for July-September and October foliage season (when prices climb 25-35%); one week suffices off-season. Xinduqiao's best photography-adjacent hotels sell out first; Shangri-La Town (Daocheng) base hotels near the park gate go next. Cancel-flexible rates are worth the small premium in monsoon season.
10 Pro Tips for the Loops
The 6:30 Rule
Depart by 6:30 AM on driving days: you dodge tour-bus convoys, catch mirror-still morning light, and bank hours against the monsoon's afternoon tantrums. Every veteran loop driver lives by this.
Never Skip Danba's Low Night
The 1,800 m sleep is not a scheduling accident — it is acclimatization gold. Travelers who "optimize" it away meet Litang's 4,014 m with unready lungs. The staircase works only if you climb every step.
Refuel at One-Third
Highland fuel stations space out 100+ km and close early in places. The rule is mechanical: needle at one-third, next station, fill. Renting? Return trips add mountain consumption no city formula predicts.
Back Gate at Moshi Park
Enter from the rear entrance and walk the loop forward: you skip the front-gate shuttle queue and meet the stone forest with morning backlight instead of noon crowds. Locals consider this basic knowledge.
The Yuzixi Sunset Bet
The ¥30-50 viewpoint fee buys a 360-degree Gongga panorama at golden hour — but only when clouds cooperate. Hedge: check the sky at 15:00, commit by 16:00, and bring the down jacket; the summit wind is winter-grade even in August.
Checkpoint Prep for Foreigners
Keep your passport reachable on drives — checkpoints log foreign travelers, and drivers handle registration faster with documents in hand. A phone photo of your passport's bio page is a useful backup, never a substitute.
Yading's Cart Math
The ¥80 electric cart from Chonggu to Luorong saves 7 km each way — nearly two hours of walking you'll want for the Milk Lake climb above. Take it up, walk the scenic descent if energy allows.
Ask Hotels About 2026 Free Windows
Regional promotions shift year to year — Yading's Aug 1-Oct 31 free-entry window and the Siguniang combo are 2026 examples. Booking platforms don't always surface them; hotels and operators know the current calendar.
Butter Tea Strategy
Accept the first cup in any Tibetan home or monastery guesthouse — it is hospitality, salt-loaded, and genuinely warms a 4,000 m afternoon. Refill etiquette mirrors tea culture everywhere; a smile covers any language gap.
Fly Out of Daocheng
If ten days is tight, drive the loop one way and fly back: Daocheng Yading Airport (4,411 m) reaches Chengdu in 65 minutes, converting two driving days into one flight — and skipping repeated altitude exposure on the return.
Frequently Asked Questions
Can foreigners drive the western Sichuan loops themselves?
Not with a foreign license or IDP — neither is valid in mainland China under any circumstances. Legal self-driving requires a Temporary Driving Permit (obtainable in Chengdu with your passport, home license, certified translation and 1-5 business days) or a full Chinese license. Most foreign travelers instead charter a 7-seat van with a professional driver (¥800-1,200/day split across the group) — safer on the passes and legally simpler.
Do I need a permit for western Sichuan as a foreigner?
No — for the loops themselves. Western Sichuan requires no Tibet Travel Permit, no Alien's Travel Permit and no mandatory guide: your passport is sufficient everywhere described in this guide. The one exception is Seda's Larung Gar monastery, currently restricted to mainland Chinese ID holders; the rest of Seda county remains open to foreigners.
Small Circuit or Big Circuit — which should I choose?
Four to six days or first plateau trip: the Small Circuit — Siguniang, Danba, Moshi Park, Tagong, Xinduqiao, Kangding in a compact, lower-altitude, sedan-friendly loop. Nine to eleven days with acclimatization time and a hunger for the full Kham experience: the Big Circuit, adding Litang's sky-city and Yading's sacred-peak trekking. Both share the Chengdu start and the same infrastructure boom.
When is the best time of year for the loops?
Mid-June and mid-to-late October are the sweet spots: peak landscapes without peak crowds. July-August delivers greenest grasslands but monsoon afternoons; September-early October offers the clearest air and gold foliage (plus National Day crowds); winter brings sublime clarity but icy passes requiring chains and experience.
How bad is altitude sickness on these routes?
Manageable by design — the loops' sleeping altitudes form a natural staircase (3,200 → 1,800 → 3,300 → 4,000 m) that acclimatizes you progressively. Follow three rules: never skip the Danba low night, hydrate 3-4 liters daily, and don't sleep more than 500 m above the previous night past 3,000 m. Diamox 125 mg twice daily (consult your doctor) halves the risk in clinical trials. Worsening symptoms at rest: descend.
Is the Zheduoshan pass still worth crossing?
The 2026-opened tunnel now carries through traffic under the mountain — faster and weather-proof. The old 4,298 m pass road remains open as a scenic option: add an hour for the classic switchback photography and prayer-flag views. Most travelers tunnel in, photograph on the Xinduqiao side, and save the pass for a clear morning.
What is the budget for the loops?
Small Circuit: ¥1,200-1,900 per person (4 sharing a chartered van) excluding flights — covering car, fuel, hotels, tickets under ¥350 total, and meals. Big Circuit: roughly double for the extended days, with Yading's tickets and the Litang-Daocheng leg adding the difference. Peak-season hotel rates rise 25-35%; booking a month ahead holds prices down.
Can I visit Seda's Larung Gar as a foreigner in 2026?
No. Entry is currently limited to mainland Chinese resident ID holders, with no booking channel or guided workaround for foreign passports — including Hong Kong, Macau and Taiwan travelers. The surrounding Seda county (Donggar Monastery, Jinma Grassland, Gesar Center) remains open and free. Verify current policy with your operator before planning around it.
