Finding a parking place around the Red Bull Arena can be tough. It's better to leave your car at one of the park and ride car parks around the city. From there you can take a tram to the stadium. We advise the parking lot on Schonauer Ring. Tram 15 will take you to the stadium in fifteen minutes (get off at Sportforum Süd).
From the centre of Leipzig, you can take trams 3, 4, 7 and 15 to the stadium.
