Getting there & away
Buses leave from the corner of Maipú and Juana Fadul in Ushuaia several times daily from 9am to 6pm, returning approximately every hour between 8am and 8pm. Depending on your destination, a round-trip fare runs ARS$30 to AR$40, and you need not return the same day. Private tour buses cost AR$90 for a round-trip. Taxi fares shared between groups can be the same price as bus tickets.
The most touristy and, beyond jogging, the slowest way to the park, El Tren del Fin de Mundo (02901-431600; www.trendelfindemundo.com.ar; one way/round-trip AR$65/70, plus park entrance fee) originally carted prisoners to work camps. It departs (sans convicts) from the Estación del Fin de Mundo, 8km west of Ushuaia (taxis AR$25 one way), three or four times daily in summer and once or twice in winter. The one-hour, scenic, narrow-gauge train ride comes with historical explanations in English and Spanish. Reserve in January and February, when cruise-ship tours take over. If you are not a train fanatic, take it one way and return via minibus.
Hitchhiking to the park is feasible, but many cars will already be full.
