Book a parking spot in BSM Pedralbes - Marquès de Mulhacén car park

ZBE Rondes de Barcelona (LEZ or ZTL in some countries) is an area of over 95 km², comprising Barcelona and the municipalities surrounding the ring road, which applies environmental restrictions to vehicle traffic.

From Monday to Friday, between 7:00 am and 8:00 pm, only ecological vehicles and those with the environmental label B or C of the Spanish Traffic Authority -DGT- are allowed to circulate here.
Vehicles registered outside Spain are not classified according to the environmental criteria of the DGT environmental label.

To drive there without being ticketed, all foreign vehicles must register and pay the corresponding tax.
