Villazón is a town in southern Bolivia, on the border with Argentina.
The town is a busy trading hub, with large quantities of goods flowing north.
It is also a heavily used transit hub for tourists passing into Bolivia.
A train line connects Villazón with Tupiza, Uyuni and Oruro.
Two train services, the Expreso del Sur and slightly cheaper Wara Wara del Sur, each run twice a week.
