Compared to Italy, transport in Germany is quite expensive, even tickets for regional trains. Therefore, an extensive carsharing network has developed with which university cities are well connected.
For those who prefer to take the train, however, it is worth buying the "BahnCard", the discount card issued by the German railways. Thanks to a special offer, the "BahnCard" for students is much cheaper than the standard one. The "BahnCard 25" costs 39€/year and offers a 25% discount on all domestic trains. The "BahnCard 50" costs just 69€/year and offers a 50% discount on domestic trains and 25% discount on cross-border trains.
Students in Munich often contact the South Tyrolean travel agencies that offer day trips to Munich.
An alternative is also Flixbus which offers bus trips throughout Europe.
