It is the second most populous urban area in the region of Macedonia after Thessaloniki. The close distance between the two cities (68 km), has been beneficial for Katerini's development over recent years.

It is served by Intercity, Proastiakos (suburban train) and local trains on the main Athens-Thessaloniki railway line and there is a comprehensive regional and national bus service with its hub in the city.
A popular tourist destination in northern Greece, Katerini is close to the sea (7 km) and to several archaeological sites of great interest such as the ancient city of Dion (5th century BC, 17 km away), ancient Leivithra (27 km away), ancient Pydna (16 km away) and the Castle of Platamon.
