To save some money traveling by train in Bavaria, get a Bayern-Ticket. Get a few folks together and take advantage of the 29€ ride all day pass – good up to 5 travelers. Don’t know 4 other people? That’s fine just hang out by the ticket machines and ask folks. Seriously! Regular fare is 30€ or so, this way it’s only 6€. that’s for the local not the express trains. Express is about 50€ and saves only 30 minutes or so from Nürnberg to München. But for 10% of the cost it’s definitely worth it!
