Geology of Laos
Some of the most extensive limestone cave systems in Asia can be found in Laos.
The limestone forest in Khammouane has the highest concentrations of caves in
Laos.
Vang Vieng, just north of Vientiane is also well-known for karst mountains and
caves.
But the most famous caves in Laos are way up in Houaphan Province's Vieng Xay
district.
These caves served as a base for the Lao Revolutionary Forces during the Second
Indochina War and were transformed imto shelters and bunkers.
