El Tren del Fin del Mundo Travel Guide

($25 one way, plus $5 park entrance; tel 02901/431600) is one of Ushuaia's most publicized attractions, and can be used as a rather gimmicky means of entering or leaving the national park. It is the most southern of the world's railways, but offers nothing like the same experience as Argentina's other tourist railways. What it lacks is a sense of authenticity - the feeling that you may not be on anything other than a tourist toy train - and the price reflects the high investment outlay of the project rather than real value for money. Still, steam enthusiasts and youngsters will enjoy the 4.5-kilometre, forty-minute trip, which passes through woodland, meadows spiked with the stumps of logged trees and reconstructions of Yámana dwellings by the Río Pipo. Avoid going on cool, rainy days, as you won't see much, what with the mountains being in cloud, condensation on the windows, and the steam from the locomotive. The main station is 8km west of Ushuaia on the road to the national park (buses leave Ushuaia's Muelle Turístico; 4 daily; $4 return), and the other is just inside the national park's boundaries. In high season, there are at least four departures a day from each.
