One part of the old rail line that linked Arica with La Paz, Bolivia, has been restored, allowing you to ride a tourist train that runs once a week between Arica and the Lluta Valley town of Poconchile, some 37km to the northeast. The 1950s vintage train cars currently depart Saturdays at 10:30am and arrive back in Arica at 3:30pm, after a one-hour stop in Poconchile.
The train departs from the station in Chinchorro, about 3km northeast of the center. Call ahead or confirm with the tourist office that the train is running. Outside high season (December to mid-March) it tends to run only twice a month.
