Barcelona is a compact city, easy to get around on foot or by public transport. If you are driving, it is worth bearing in mind that traffic is regulated, with pedestrian priority zones and streets with restricted access.
On-street parking is limited and regulated through green and blue zones. There is also an extensive network of underground car parks, both public and private, especially in the city centre.
The city operates a Low Emission Zone (ZBE), which restricts access for vehicles based on their emissions, particularly on weekdays. It is recommended to check in advance whether a vehicle is allowed to circulate and to register it if necessary: zberegistre.ambmobilitat.cat
In general, private cars are only useful in specific situations; for travel within the city centre and for everyday journeys, public transport, cycling and walking are more practical, agile and sustainable options.
