World’s first underwater heritage museum: Baiheliang Underwater Museum preserves 1,200-year-old stone hydrological inscriptions at their original site 40 meters beneath the Yangtze River. Visitors descend via a dedicated escalator to an enclosed underwater corridor to admire the “underwater forest of steles” up close, experiencing a unique blend of ancient hydrological wisdom, historical calligraphy and modern heritage protection engineering.

World’s largest man-made cave nuclear project: The 816 Project is a once top-secret Cold War engineering marvel hidden entirely inside a mountain. With 20 kilometers of tunnels and a 79-meter-high reactor hall, this monumental Third Front Construction site showcases China’s national defense engineering achievements and the extraordinary dedication of tens of thousands of anonymous workers, delivering a deeply impactful and educational experience.

Dual themes of culture and industrial history: The itinerary combines two distinctive Fuling landmarks, perfectly balancing cultural heritage exploration with industrial history and national defense education. It offers both the poetic depth of Yangtze River civilization and the solemn weight of modern engineering history, creating a rich and unique travel experience.

Efficient same-day round trip: Departing and returning to downtown Chongqing within a single day with no overnight stay required, the tour covers two one-of-a-kind attractions in a compact schedule, ideal for travelers interested in history, engineering and culture.

Flexible private experience: Travel with an exclusive guide and private vehicle throughout the trip. You can freely adjust your visiting pace at each site, with professional commentary to help you fully understand the historical background and engineering significance of both attractions.
