Quick Answer

Chengdu and Chongqing make a varied southwest China trip: Chengdu combines the panda base, teahouses, Sichuan food, and the UNESCO-listed Dujiangyan–Qingcheng property; Chongqing is known for its steep urban terrain and river views. High-speed trains connect the cities, but journey time, departure station, and arrival station vary by service—check the exact date on 12306 before building the transfer day.

Give it 5–6 days for a comfortable version (about 3 in Chengdu, 2 in Chongqing), or 4 days at minimum (2 + 2). Add 1–2 days if you want the Leshan Giant Buddha and Mount Emei side trip from Chengdu.

Spring and autumn are easier seasons for long outdoor days. Summer can bring severe heat in Chongqing; check the forecast and heat warnings, and move steep outdoor walks to cooler hours. If you add Mount Emei, check current access conditions before choosing a date.

Why Pair These Two Cities

They are close, well connected, and deliberately different, so the trip never feels repetitive:

  • Chengdu is the easy-going introduction to Sichuan: pandas, teahouses, Sichuan cuisine at its source, and two of China's great heritage sites (Dujiangyan and Mount Qingcheng) within a short train ride.
  • Chongqing is the spectacle: a city built on cliffs and hillsides where the metro runs through a building, light rail crosses river gorges, and the two-river junction lights up at night.

The rail connection makes the pairing practical, but do not assume a fixed journey time or station pair: both cities have multiple passenger stations, and service patterns change.

How Many Days

  • Minimum (4 days): 2 full days Chengdu + 2 full days Chongqing. Enough for pandas, central Chengdu, and Chongqing's core sights, but tight.
  • Comfortable (5–6 days): 3 Chengdu (add Dujiangyan or Leshan) + 2 Chongqing + buffer.
  • With the mountains (7–8 days): add the Leshan Giant Buddha and Mount Emei side trip, which really wants an overnight near Emei rather than a rushed day trip.

Suggested Route

Days 1–3 — Chengdu

  • Chengdu Panda Base (成都大熊猫繁育研究基地). The signature stop. The official English visitor page lists seasonal morning and afternoon entry windows and requires advance online real-name reservations for most visitors; passports are accepted. Check the booking channel, current price, session, and entry-document instructions for your date before you go. Plan a half-day and choose a morning session if it fits your schedule.
  • Central Chengdu. Kuanzhai Alley (宽窄巷子), People's Park teahouses, Jinli, and Sichuan food. Easy, flat, walkable.
  • Day trip — Dujiangyan + Mount Qingcheng (都江堰-青城山). The irrigation system and Mount Qingcheng are one UNESCO World Heritage property, inscribed in 2000. Check 12306 for a suitable train to the area and leave time for local transfers; the heritage sites are not at the railway station, so do not plan this as a station-to-station half-hour visit.

Days 4–5 — Chongqing

Take the high-speed train over (see below) and switch gears completely.

  • Hongyadong (洪崖洞). A multi-level stilt-house complex near Jiefangbei and the Yangtze–Jialing confluence. It is especially busy in the evening; check current access and crowd-management notices.
  • Yangtze River Cableway (长江索道). A river crossing with city views. The Chongqing government's current guide lists seasonal hours and rail access from Xiaoshizi; check the operator's live notice for disruptions, tickets, and any holiday changes.
  • Ciqikou Ancient Town (磁器口). A historic district in Shapingba with traditional residences, food, and local life. It is farther from central Jiefangbei than the other stops, so group it with nearby stops rather than squeezing it between short central-city visits.
  • Feel the terrain. Chongqing's appeal is its verticality: ride the Liziba monorail (which passes through a residential building), walk the multi-level streets, and see the two-river night skyline from a viewpoint or river cruise.

Optional Days 6–8 — Leshan + Mount Emei

Check 12306 for trains to Leshan or Emeishan and plan the final transfer to each scenic area separately. The Leshan Giant Buddha and Mount Emei are different visits; combining them with the two cities needs more time than a rushed day trip. Before adding Mount Emei's Golden Summit, note that 2026 works have constrained bus and cableway capacity, limited daily Golden Summit tickets to 8,000, and are expected to continue into 2027. Confirm current access, timed entry, and overnight transport before committing to the summit plan.

The Train Between Them

There is no safe universal journey-time or fare figure for this corridor: trains, stops, ticket inventory, and endpoint stations vary by date. Chengdu and Chongqing each have multiple stations, and Chongqing East opened in 2025 alongside Chongqing North and Chongqing West. Search the exact route and date on 12306, then check the full Chinese station name against your hotel and transfer plan. Keep a buffer for crossing either city; a station name containing the city name does not mean it is next to the city center.

Best Season

Spring and autumn are clearly best. The one season to avoid is mid-summer (July–August): the National Climate Center ranks Chongqing at the top of China's hottest summer cities on a heat-index basis, and in the 2022 heat wave a Chongqing station hit 44.5°C, with a July–August mean well above normal. The Sichuan Basin traps heat and humidity, so summer sightseeing — especially Chongqing's vertical, stair-heavy streets — is genuinely punishing. Spring (March–June) and autumn (September–November) give you mild days; note the basin is often cloudy and can be drizzly, so pack a light rain layer.

Common Mistakes

Underestimating Chongqing's terrain

Chongqing is not a walk-in-a-grid city — it is stacked vertically, and "500 meters away" on the map can mean several flights of stairs or a different elevation entirely. Build in extra time, use the metro and cableway liberally, and don't over-pack the days.

Traveling in July–August

Assuming a summer calendar date guarantees comfortable sightseeing. Check the forecast close to departure, plan shade and indoor breaks, and take official heat warnings seriously.

Not reserving the panda base — or arriving midday

Most visitors need an advance online real-name reservation. Check the entry session and the identity-document instructions for your visit date, then plan enough time for the chosen gate window.

Mixing up the stations

With multiple stations in each city, it's easy to book the wrong one and add an hour of cross-town transfer. Match the station to your hotel and confirm it on your ticket.

Fit It Into a Bigger Route

This pair works as a standalone 5–8 day trip or as the southwest leg of a longer itinerary:

  • Add Yunnan: consider a southwest extension into Dali or Lijiang; check current flight and rail connections before fixing the route.
  • Add Zhangjiajie: Chongqing has a rail connection toward Zhangjiajie on the 渝厦 corridor. Check the exact service and station on 12306 before adding it to the itinerary.
  • Slot into a two-week trip: Chengdu already anchors many Beijing–Xi'an–Chengdu–Shanghai routes; adding Chongqing turns the Chengdu stop into a richer southwest section.
  • How to buy China train tickets — booking the Chengdu–Chongqing and side-trip legs on 12306.
  • 14 Days in China — the wider route this southwest loop plugs into.
  • Yunnan (Hidden China) — the most natural onward extension from the southwest.
