Themed hub
Five legitimate panda-viewing sites — three research bases (high probability of sightings) and two reserves (effort + lower probability + better scenery). All in Sichuan.
Research bases vs reserves
Pandas live wild in roughly the western edge of Sichuan and adjacent slivers of Shaanxi and Gansu — bamboo-forest highlands above 1,500m. Total wild population is around 1,800; another 600 or so live in captivity, mostly in Sichuan. Outside this region they exist only on loan to zoos, including the handful of pandas China has loaned to other countries since the 1970s on a continually-renewable basis.
For visitors there's a real choice: research base or reserve. Research bases (Chengdu Base, Bifengxia, Dujiangyan) are zoos in scientific dress — large landscaped enclosures, near-certain panda sightings, structured visitor flow, half-day commitment. Reserves (Wolong, the Sichuan Sanctuaries broadly) are protected wild habitat with limited access — guided hikes, small probability of a wild sighting, larger time and physical commitment, more legitimate "I saw a panda in its natural setting" credibility.
For a first visit, the Chengdu Research Base is the canonical answer. Arrive by 8 a.m. opening; pandas are most active at feeding time (around 8.30–10.30) and sleep through most of the afternoon. The base is 30 minutes from Chengdu's centre by metro. Ticketing is online-only via Sichuan Tourism's WeChat mini-program; foreign passports work but the booking flow is in Mandarin.
For a second-tier option that gives more, Dujiangyan Panda Base is paired with the 2,300-year-old Dujiangyan irrigation system (UNESCO listed) — together they make a strong full-day itinerary out of Chengdu. The Volunteer Programme at Dujiangyan is the only place where paying foreign visitors get hands-on time with pandas under staff supervision; book directly with the base.
Research base · Chengdu
The flagship panda-viewing facility — 30 minutes north of Chengdu's centre. Multiple enclosures across landscaped grounds. Visiting time: 3–4 hours. Arrive by 8 a.m. opening for active feeding behaviour; pandas sleep most of the afternoon.
Volunteer base · Dujiangyan
Smaller, calmer than the Chengdu base. The 'Panda Volunteer Programme' (8 a.m.–4 p.m. day for paying foreign volunteers) is run from here — under-the-supervision-of-staff cleaning, feeding, observation. Combine with the Dujiangyan irrigation system UNESCO site.
Reserve / sanctuary · Wenchuan, Aba Prefecture
The original wild panda research reserve — about 3 hours' drive from Chengdu up onto the Tibetan-Plateau edge. The 2008 Wenchuan earthquake destroyed the original Wolong Centre; Shenshuping (within the reserve, near Gengda) is the rebuilt successor. Reserve hiking requires a guide. Detail page coming.
Research base · Ya'an
About 2.5 hours southwest of Chengdu. Larger forested enclosures than the Chengdu base. Less polished and less crowded; the buses through the reserve are part of the experience. Detail page coming.
Reserve / sanctuary · Across western Sichuan
UNESCO World Heritage Site (2006). Spans seven nature reserves and nine scenic parks across western Sichuan — the world's largest contiguous panda habitat. The umbrella designation; individual reserves (Wolong, Mount Siguniang, Bifengxia) are visited separately.
