Discover more about Viengxay caves

The Viengxay Caves, also known as the “Hidden City”, represent a network of almost 500 caves in the Houaphanh Province of Laos. During the Second Indochina War (1964-1973), these limestone karsts served as a refuge for more than 20,000 civilians and Pathet Lao soldiers from American bombardment. The caves weren't just bomb shelters; they were transformed into a functional underground city, complete with residences, hospitals, schools, government offices, a theater, and even a clothing factory. Today, the Viengxay Caves stand as a historical and cultural landmark, offering visitors a unique insight into Laos's wartime past and the resilience of its people. Exploring the caves is like stepping back in time, with preserved living spaces, kitchens, and bomb shelters that offer a glimpse into daily life during the war. Key caves to explore include Kaysone Phomvihane's Cave, the former residence and office of the Pathet Lao leader, and Prince Souphanouvong's Cave, which served as an important command center. The Xanglot Cave, once a central area for rallies and meetings, and the Artillery Cave, a military installation, are also worth visiting. The Viengxay Caves Visitor Centre provides tourist information and displays about the history of the conflict. Audio tours in both English and Lao are available, enhancing the visitor experience.
