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 closed in 1959, and today only a few hundred hardy souls remain. Take any bus to Potosà and ask to be dropped off at Pulacayo (B$5, 30 minutes) or book a tour. There is a fee of B$10 to enter the village.
Also worth seeing here is the mansion of the 22nd president of Bolivia, Aniceto Arce RuÃz. 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 rail car that bears the bullet holes from the attack.
