Joining a truly fascinating 18-point tour is the only way to see Vieng Xai's seven most important war-shelter cave complexes, set in beautiful gardens backed by fabulous karst scenery. A local guide unlocks each site while, an audioguide gives a wealth of first-hand background information and historical context. The Kaysone Phomvihane Cave still has its air-circulation pump in working order and is the most memorable of the caves.
Tours leave at 9am, 11am, 1pm and 4pm from the caves office.
