Trilogy Tour Wuling Mountain, Baiheliang Museum and 816 Project

Highlights

Inclusions

Itinerary

1. Pick up from hotel and be on the road for 1.5 hours to get our first site.

   1.5 h

2. The White Crane Ridge Underwater Museum is the world’s first and only in-situ underwater heritage museum – a place where you stand 40 meters below the Yangtze River and gaze through portholes at stone carvings over 1,200 years old. Once a natural ridge that appeared only during dry seasons, it collected 170 inscriptions from Tang Dynasty scholars and officials, including ancient poetry, calligraphy, and the earliest known records of Yangtze river levels. When the Three Gorges Dam permanently submerged the ridge, China built an underwater steel shell to protect it in place. Visitors take a submerged escalator and a tunnel down to observation windows, where history floats silently outside the glass – no diving suit required.

   1 hAdmission included

3. The 816 Nuclear Project is a decommissioned underground plutonium production facility carved entirely into a mountain in Chongqing – the largest man-made cave system in the world, hidden from public knowledge for nearly 40 years. Over 20,000 soldiers and engineers worked in absolute secrecy during the Cold War, digging 18 massive concrete-lined halls and over 12 miles of tunnels deep inside Wuling Mountain. Visitors today walk through the reactor hall that was designed to house a 150-megawatt nuclear reactor, stand inside the giant computer room that never received its final equipment, and feel the cold wind blowing through blast-proof doors weighing over 30 tons. It is a haunting monument to wartime paranoia, abandoned ambition, and the engineering extremes of 20th-century China – a secret underground city that never went critical, now open to the light.

   1.5 hAdmission included

4. The Wuling Mountain Great Rift Valley is a raw, narrow slash through the limestone heart of Chongqing's eastern highlands – a place where stone walls rise hundreds of meters on both sides and the sky becomes a thin white line overhead. A wooden walkway bolts directly onto vertical cliffs, leading visitors through ancient fissures carved by underground rivers over millions of years. You pass through the "Heavenly Gate," cross a swaying bridge between two peaks, and listen to water dripping from moss-covered rocks in near-silence. Unlike the man-made secrets of the 816 Nuclear Project or the submerged history of White Crane Ridge, this is nature's own hidden corridor – cool, damp, and dramatically untouched. No elevators, no portholes, just a deep crack in the earth waiting to be followed.

   4 hAdmission included

5. After visiting all three sites, we will drive back to your hotel.

   1.5 h

About Chongqing

Chongqing is a vast hilly city where the Yangtze meets the Jialing in south-west China, known for fiery hot pot, steep streets and a skyline lit at night.

Chongqing spreads across steep hills at the meeting of the Yangtze and Jialing rivers, so its roads climb and drop, cable cars cross the water, and a monorail line passes through a residential tower. It is one of China's four municipalities under direct central control, and it served as the Nationalist government's capital during the Second World War. Hongyadong, a cliffside complex built in the style of the region's stilted houses, is lit up at night.
