At this virtual ghost town, brilliantly colored rocks rise beside the road and a mineral-rich stream reveals streaks of blue, yellow, red and green. The silver mines north of the village finally closed in 1959, and today only a few hundred hardy souls remain. There are several kilometers of mine tunnels to explore.
Also worth seeing here is the mill that spins llama wool into cloth, and the mansion of the 22nd President of Bolivia, Aniceto Arce Ruíz. Nearby is a collection of decaying steam locomotives that were originally imported to transport ore. They include Bolivia's first steam engine, El Chiripa, and the train that was robbed by legendary bandits Butch Cassidy and the Sundance Kid, including a wooden railcar that bears the bullet holes from the attack.
