Nestled in the remote mountains of Houaphanh Province, near Sam Neua, the Vieng Xai Caves are one of Laos’ most significant historical and cultural landmarks. These vast limestone caves once served as a hidden underground city during the Laotian Civil War (1964-1973), providing refuge for thousands of Pathet Lao soldiers and civilians as they endured heavy bombings by U.S. forces. Today, the caves offer a fascinating glimpse into Laos’ wartime history and the resilience of its people.
Visiting the Vieng Xai Caves is like stepping into a secret world frozen in time. More than 480 caves were used as homes, hospitals, schools, military headquarters, and government offices during the war. The caves were not just shelters—they became an entire underground society, where people lived, worked, and planned for the future of Laos.
Some of the most significant caves you can explore include:
- Kaysone Phomvihane’s Cave – The residence and office of the Pathet Lao leader, featuring a meeting room, living quarters, and a bomb-proof bunker.
- Prince Souphanouvong’s Cave – The home of the “Red Prince” and an important command center.
- Theater Cave – A cultural space where performances and films were shown to boost morale during wartime.
- Hospital Cave – A fully functional underground hospital where wounded soldiers and civilians were treated.
- Market Cave – A communal space where residents could trade food and supplies.
Each cave tells a story of survival and ingenuity, with remnants of wartime life still visible today.
