From Munich: Salzburg Day Trip by Train

Visit the hometown of Wolfgang Amadeus Mozart on a full-day tour from Munich. Travel by train and in the imperial city, visit his place of birth (optional), his residence, the streets he walked, and the cafés he drank in.
Salzburg is also one of the most popular set-jetting destinations in the world for one simple reason, “The Sound of Music.” Visit sites you will remember from the silver screen such as the beautiful Mirabelle Gardens where Julie Andrews and the children were filmed singing “Do-Re-Mi.”

An expert guide will take you on a train ride from Munich to Austria. You will be provided with a map and get a 1.5-hour orientation tour through the major sites. 
Explore one of the finest preserved medieval old towns in Europe, crisscrossed with romantic winding shopping streets and venerable market places adorned with outstanding architectural monuments of the later baroque era.
See piazzas and fountains, the stunning Domkirche Cathedral, pleasure gardens, palaces, and churches, monasteries and catacombs, and confectionaries and patisseries. You will also go to the oldest restaurant on the continent.

You will then have 3 hours to explore the city for yourself, before meeting up for the return journey.
During your free time, you can visit the breathtaking 900-year-old fortress Festung Hohensalzburg, the magnificent edifice that dominates the city's skyline, itself framed by the spectacular encirclement of mountains stretching into the horizon.
