Barcelona is well connected by road to the rest of Catalonia, Spain and the south of France, thanks to a network of motorways and main routes that make it easy to reach. The Ronda de Dalt and the Ronda del Litoral form the main ring roads, distributing traffic and linking the different neighbourhoods.
Once in the city, however, getting around is geared towards walking, public transport and other more sustainable options. Private car use is regulated, on-street parking is limited, and it is worth bearing in mind the Low Emission Zone, which restricts access for certain vehicles depending on their emissions.
For that reason, arriving by car can be useful in some cases, but once here Barcelona is generally easier to navigate using other forms of transport.
