The region spanning Sichuan, Chongqing, Yunnan, Guizhou, and the accessible portions of Tibet Autonomous Region covers approximately 1.36 million square kilometers with transportation infrastructure that varies from high-speed rail corridors to unpaved mountain roads requiring permits. Chengdu Shuangliu International Airport and Chengdu Tianfu International Airport, which opened June 2021, together handle over 74 million annual passengers, while Kunming Changshui International Airport serves as the primary hub for Yunnan with capacity for 38 million passengers. Chongqing Jiangbei International Airport processed 44.7 million passengers in 2019, making it the ninth-busiest airport in China. Guiyang Longdongbao International Airport and Lhasa Gonggar Airport, located 62 kilometers from Lhasa at 3,600 meters elevation, complete the major air access points. Domestic flights connect these hubs to secondary cities including Lijiang, Dali, Shangri-La, Jiuzhaigou Huanglong Airport at 3,448 meters elevation, Xichang, Kangding, Panzhihua, Zunyi, Nyingchi at 2,949 meters, and Shigatse. Jiuzhaigou Huanglong Airport sits 88 kilometers from Jiuzhaigou Valley with shuttle buses requiring 90 minutes, while altitude sickness affects some passengers immediately upon arrival due to the rapid ascent from sea-level departure cities.
The Chengdu-Chongqing high-speed rail operates at 350 kilometers per hour with travel time of 62 minutes covering 308 kilometers between the two cities. The Chengdu-Kunming railway, completed in 1970 through the Hengduan Mountains, required 427 tunnels and 991 bridges over its 1,090-kilometer route, with construction fatalities exceeding 2,000 workers. The newer Chengdu-Guiyang high-speed line opened December 2019, reducing travel time to 2.5 hours for the 650-kilometer distance. The Chengdu-Dujiangyan intercity railway reaches the irrigation system in 30 minutes, while the Chengdu Metro network extends to 558 kilometers across 13 lines as of 2023, with Line 10 connecting Shuangliu Airport to the city center in 50 minutes. Chongqing Metro spans 432 kilometers across 10 lines, including Line 2 which crosses the Yangtze River on the Dongshuimen Bridge. Kunming Metro operates 6 lines totaling 228 kilometers, with expansion continuing. The Guiyang-Guangzhou high-speed rail passes through karst terrain requiring 238 tunnels over 857 kilometers. The Qinghai-Tibet Railway reaches Lhasa at 3,656 meters after crossing the Tanggula Pass at 5,072 meters, the highest railway point globally, with pressurized passenger cars and supplemental oxygen available due to reduced atmospheric pressure at 58% of sea level.
Travel between Chengdu and Jiuzhaigou Valley requires either the Jiuhuang Airport route or a 450-kilometer road journey taking 8-10 hours via National Highway 213 and Provincial Highway 301. Tourist buses depart Chengdu's Chadianzi Bus Station and Xinnanmen Bus Station daily, with tickets costing 150-170 yuan one-way. The road ascends from 500 meters in Chengdu to over 3,000 meters at multiple passes, with the route prone to closure from June through September during the monsoon season due to landslides. The November 2017 earthquake measuring 7.0 magnitude destroyed portions of the road, requiring reconstruction completed in 2019. Private car rentals require Chinese driver licenses, which foreign nationals cannot obtain as tourists, limiting self-drive options to those with residence permits. Hiring drivers with vehicles costs 600-1,200 yuan per day depending on vehicle type and distance, with multi-day plateau trips commanding higher rates due to altitude risk and road conditions.
Chengdu to Kangding spans 320 kilometers along National Highway 318, the overland route to Lhasa that continues 2,142 kilometers from Chengdu to the Tibetan capital. The road crosses the Erlang Mountain Tunnel at 2,182 meters length, cutting the previous pass route that frequently closed in winter. Kangding sits at 2,560 meters where the Sichuan Basin meets the Tibetan Plateau, serving as the gateway to western Sichuan's Tibetan regions. From Kangding, roads branch to Tagong Grassland 110 kilometers northwest, Danba County 180 kilometers north featuring Tibetan stone watchtowers, and Litang County 285 kilometers west at 4,014 meters elevation, one of the world's highest towns. The Chengdu-Litang route via Kangding requires two days with overnight stops, as covering 650 kilometers of mountain switchbacks in one day increases altitude sickness risk from ascending too rapidly. Buses from Chengdu's Xinnanmen Station to Kangding depart twice daily at 06:30 and 10:00, taking 6-7 hours and costing 130 yuan. Continuing to Litang requires changing buses in Kangding, with the second leg taking 7-8 hours over unpaved sections above 4,000 meters.
The Sichuan-Tibet Highway's northern route (National Highway 317) and southern route (National Highway 318) both originate in Chengdu, diverging after Kangding. The southern route through Litang, Batang, and Markam covers 2,142 kilometers to Lhasa over terrain reaching 5,130 meters at Mila Mountain Pass. The northern route via Danba, Ganzi, Dege, and Chamdo extends 2,412 kilometers with higher average elevations and more remote sections. Both routes remain partially unpaved, with the southern route seeing heavier truck traffic supplying goods to Tibet. Landslides close sections during summer monsoons from June through August, while winter snow from November through March blocks high passes sometimes for weeks. The Tibet Entry Permit, required for all non-Chinese nationals entering Tibet Autonomous Region, prohibits individual travel, mandating tour groups with registered guides and pre-arranged transport. The permit system extends to certain areas of western Sichuan including Yading Nature Reserve and areas west of Litang, where Public Security Bureau checkpoints verify documentation. Permits cannot be obtained by individuals and must be arranged through registered travel agencies, with processing taking 15-20 days and approval not guaranteed.
Chongqing's urban transport includes the Yangtze River cableway spanning 1,166 meters between Yuzhong District and Nan'an District, carrying 40 passengers per cabin across the river in 4 minutes. The city's monorail Line 2 runs through residential buildings at the Liziba Station, where the track passes through the sixth through eighth floors of a 19-story apartment block built simultaneously with the transit line in 2004. Chongqing's Chaotianmen Port serves as a departure point for Yangtze River cruises downstream through the Three Gorges to Yichang in Hubei Province, though this route exits the southwest region. City buses charge 2 yuan flat fare, while the metro uses distance-based pricing from 2 to 10 yuan. Taxis start at 8 yuan for the first 3 kilometers, with GPS tracking standard and payment through WeChat Pay or Alipay more common than cash since 2018.
Kunming serves as the hub for reaching Dali, Lijiang, and Shangri-La in northwestern Yunnan. The Kunming-Dali high-speed rail opened July 2018, covering 330 kilometers in 2 hours compared to the previous 6-hour conventional train. Dali Railway Station sits 15 kilometers east of Dali Old Town, requiring public bus 8 or 崇圣寺三塔专线 (Three Pagodas Line) for 25 minutes to reach the ancient city. Dali to Lijiang extends another 160 kilometers via the Dali-Lijiang Railway completed January 2019, reducing travel time to 90 minutes from the previous 3-hour bus journey on Provincial Highway 221. Lijiang Railway Station lies 7 kilometers south of Lijiang Old Town, with bus 18 and tourist shuttle buses connecting in 20 minutes. Shangri-La, formerly Zhongdian, requires a 4-hour bus ride from Lijiang covering 180 kilometers on National Highway 214 as no rail connection exists. The road climbs from Lijiang's 2,400 meters to Shangri-La's 3,280 meters through the Haba Snow Mountain range, with sharp curves and precipitous drops where barrier installations remain incomplete on older sections.
Lijiang Old Town prohibits motor vehicles in the core UNESCO area, with pedestrian-only cobblestone streets covering 3.8 square kilometers. Electric carts transport luggage to guesthouses within the ancient city, charging 20-30 yuan depending on distance from entry points. Bicycles can be rented outside the old town perimeter for 20-40 yuan per day, though the surrounding modern city's hills make cycling strenuous. Dali Old Town similarly restricts vehicle access within the ancient walls, with its 1.5-kilometer north-south axis walkable in 20 minutes. Erhai Lake, located 2 kilometers east of Dali Old Town, measures 41.5 kilometers long and 3-9 kilometers wide, with a perimeter road of 115 kilometers popular for electric scooter rentals at 60-100 yuan per day. The lake sits at 1,972 meters elevation with its western shore backed by Cangshan Mountain's 19 peaks ranging from 3,500 to 4,122 meters at Malong Peak. Cycling the lake perimeter requires experienced riders 6-8 hours, while electric scooters complete the circuit in 4-5 hours with battery range sufficient for 80-100 kilometers per charge.
Provincial highways in Guizhou connect Guiyang to Anshun, where Huangguoshu Waterfall drops 77.8 meters over a 101-meter-wide curtain during peak flow in June through August. The waterfall lies 45 kilometers southwest of Anshun, accessible by dedicated tourist buses departing from Guiyang's Golden Sunshine Bus Station and Anshun's East Bus Station. The journey takes 90 minutes from Anshun and 2.5 hours from Guiyang via expressway. The Stone Forest near Kunming covers 350 square kilometers of karst limestone formations reaching 30 meters height, located 78 kilometers southeast of the city with direct buses from Kunming East Bus Station requiring 90 minutes and costing 34 yuan. Within the Stone Forest scenic area, electric carts transport visitors between the major formations, as walking the full circuit covers 8 kilometers over uneven terrain.
Lugu Lake straddles the Sichuan-Yunnan border at 2,685 meters elevation, measuring 48.45 square kilometers with maximum depth of 93.5 meters. Access from Lijiang requires 200 kilometers over mountain roads taking 4-5 hours, with buses departing Lijiang Bus Station at 08:30 and 09:30 daily, costing 70 yuan. The road crosses the Jinsha River, the upper portion of the Yangtze, and ascends through 18 switchbacks with minimal guardrails on outer curves. From Xichang in southern Sichuan, the distance to Lugu Lake measures 250 kilometers requiring 6-7 hours due to unpaved sections in the final 40 kilometers. Once at Lugu Lake, the perimeter road of 50 kilometers can be driven in 2 hours, though most visitors rent electric scooters or bicycles to explore at slower pace. The Mosuo ethnic minority, with a population around 40,000 primarily concentrated around Lugu Lake, practices matrilineal kinship systems, and visitors hire dugout canoes to reach villages on the lake's islands and far shores.
The road from Chengdu to Yading Nature Reserve in Daocheng County spans 800 kilometers requiring two days, typically with overnight stops in Kangding or Xinduqiao at 3,300 meters. Daocheng Yading Airport, at 4,411 meters the world's highest civilian airport, opened September 2013, reducing access time to 65 minutes flight plus 120-kilometer ground transfer to the reserve entrance. The airport's elevation causes operational limits, with load restrictions reducing passenger capacity on departing flights due to reduced air density affecting lift. From the reserve entrance at 2,900 meters, shuttle buses transport visitors 34 kilometers to Zhaguanbeng at 3,700 meters, then another 7 kilometers to Chonggu Temple at 3,880 meters, the base for viewing the three sacred peaks: Chenrezig at 5,958 meters, Jambeyang at 5,958 meters, and Chenadorje at 5,958 meters. Horses can be hired from Chonggu Temple to Luorong Pasture at 4,150 meters for 305 yuan round-trip covering 5 kilometers, while the final approach to Milk Lake at 4,600 meters requires hiking 5 kilometers over loose scree with no animal transport permitted.
Siguniang Mountain National Park, 220 kilometers northwest of Chengdu, requires 4-5 hours by bus from Chadianzi Bus Station, costing 65 yuan. The four peaks range from 5,025 to 6,250 meters at Yaomei Peak, the highest mountain in Sichuan Province. The park entrance at 3,200 meters provides shuttle buses to three valleys: Changping Valley extending 29 kilometers, Haizi Valley covering 19.2 kilometers, and Shuangqiao Valley spanning 34.8 kilometers. Shuangqiao Valley allows vehicle access along a paved road with 34 scenic viewpoints, while Changping and Haizi valleys require hiking or hiring horses at 200-400 yuan for 4-6 hour excursions. Overnight camping within the valleys requires permits obtained at the park entrance, with designated campsites at elevations between 3,400 and 4,200 meters where nighttime temperatures drop below freezing from October through April.
Urban transport in Lhasa includes public buses charging 1 yuan flat fare and taxis starting at 10 yuan for 3 kilometers. The city sits at 3,656 meters where altitude affects visitors within hours of arrival, with supplemental oxygen available at hotels and pharmacies. Potala Palace, rising 117 meters above Marpo Ri hill to a total elevation of 3,767 meters, limits daily visitors to 2,300 through a timed reservation system requiring advance booking. The walk from the palace base to the summit covers 1.2 kilometers over stairs and ramps, taking most visitors 45-60 minutes with rest stops for altitude adjustment. Sera Monastery lies 5 kilometers north of central Lhasa, accessible by bus 24 in 25 minutes, while Drepung Monastery sits 8 kilometers west, requiring bus 301 for 35 minutes. Both monasteries restrict photography in assembly halls and charge separate fees for chapel access beyond the 50 yuan entrance.
Travel between Lhasa and Shigatse, the second-largest city in Tibet at 3,836 meters elevation, covers 280 kilometers via the Lhasa-Shigatse Railway completed August 2014 in 2 hours 50 minutes, or by road in 4-5 hours on National Highway 318. Shigatse serves as the base for visiting Tashilhunpo Monastery, founded 1447, and for accessing Everest Base Camp on the Tibetan side. The road from Shigatse to Everest Base Camp spans 340 kilometers requiring 7-8 hours, crossing the Gyatso La pass at 5,248 meters with views of four peaks above 8,000 meters: Everest, Lhotse, Makalu, and Cho Oyu. Base camp sits at 5,200 meters, accessible only with Tibet Travel Permit plus additional Alien Travel Permit and Military Permit arranged through registered tour operators, with independent travel prohibited and checkpoints verifying group status at multiple points.
Buses in smaller cities across the southwest typically charge 1-2 yuan flat fare with routes concentrated in urban cores, leaving rural destinations dependent on infrequent rural buses or private transport. Ride-hailing apps including Didi Chuxing operate in Chengdu, Chongqing, Kunming, and Guiyang but have limited coverage in smaller cities and no service in rural areas or high-altitude regions. Motorcycle taxis, locally called 摩的 (módi), operate informally in county towns and rural areas at negotiated fares usually 5-15 yuan for trips within town, though they lack insurance coverage and safety equipment. Shared vans depart from bus stations when full rather than on fixed schedules, serving routes where passenger volume does not support regular bus service, particularly in mountainous areas where roads connect villages separated by only 20-30 kilometers but requiring 90 minutes travel time over switchbacks.
