The city centre is compact and walkable — the main sights are within 20 minutes on foot of the Hauptbahnhof. The Stadtbus network covers the suburbs. For the Palatinate Forest, a car is the most practical option, though regional trains reach Neustadt an der Weinstrasse (for the wine villages) and bus services connect the main forest settlements.
The American military presence means the city has a large English-speaking population and signs in English are common. Uber operates in Kaiserslautern alongside regular taxis.
