In Chengdu, the quintessential experience begins with visiting the Chengdu Research Base of Giant Panda Breeding to see giant and red pandas, followed by a relaxing afternoon at People's Park to soak in the local teahouse culture at Heming Teahouse. You can explore the city's rich history and traditional architecture at Wuhou Temple, Jinli Ancient Street, and the Wide and Narrow Alleys, or visit the Wenshu Yuan Monastery for a peaceful retreat. Food enthusiasts should not miss authentic Sichuan hotpot and street snacks like Zhong dumplings, and for entertainment, a Sichuan Opera show featuring face-changing acts is highly recommended. In Chongqing, known as the "cyberpunk" city, highlights include witnessing the Liziba monorail pass through a residential building, riding the Yangtze River Cableway for stunning city views, and exploring the illuminated stilt-house architecture of Hongya Cave at night. You can also wander through Ciqikou Ancient Town for a glimpse of old Chongqing, visit the Three Gorges Museum to learn about the region's history, and indulge in the city's legendary, fiery hotpot. For those with more time, day trips to the Leshan Giant Buddha from Chengdu or the UNESCO-listed Dazu Rock Carvings and Wulong Karst from Chongqing offer spectacular cultural and natural scenery.
