Erfurt lies on two federal motorways:
The Erfurt Hauptbahnhof (main train station) is quite large. Numerous ICE and IC trains pass through daily, with direct lines to Berlin, Munich, Leipzig, Dresden and Frankfurt.
The city centre is quite compact so walking is often the best way to explore the city. Regular tram services run all around the city with service intervals of every 10 minutes for most of the day. The tram service is less frequent in the evenings and no trams operate after midnight on weekdays.
Much of Erfurt's charm is found in its narrow streets, many of which are pedestrianized, with their beautiful old houses, its green areas and little bridges across the Gera river and both the Stadtpark and the Nordpark on different sides of the city center.
Check out for any festivals happening on the city, especially on public holidays.
Shops on the Krämerbrücke offer crafts and souvenirs. Around main square, Anger 1 has upmarket shops inside.
Thuringer Bratwurst! Yes, it's where they came from. You can find many stalls grilling this huge world-famous delicacy.
Die Tolle Knolle (which you could translate as "The Amazing Spud") is great for hearty potato casseroles, one of Germany's traditional dishes. On Arnstädter Chaussee 9, just off Langer Brücke.
Erfurt has numerous small bars in the city center. On the Domplatz there is a tapas bar, which is quite delicious. To the north of the Domplatz there are more bars, with one of the more popular bars being Double D's, which has numerous theme nights and drink specials.
Outside of the city-center is the disco Spot, which is quite intense and draws a younger crowd.
