The Àrea Metropolitana de Barcelona is set on the central Catalan Coast and around the capital. The metropolitan area can be divided into two zones:
* The boundary zone forming the conurbation with the city of Barcelona itself. Bordered by the Mediterranean Sea and the Serra de Collserola, the towns in this zone are Badalona, Hospitalet de Llobregat, Santa Coloma de Gramenet and Cornellà de Llobregat. Here the boundaries between municipalities are set by streets, avenues or the Llobregat and Besòs rivers.
* The adjacent metropolitan zone, made up of several towns surrounded by predominantly residential suburban areas with detached, semi-detached and terraced housing, industrial estates, parkland and woods, such as Sant Vicenç dels Horts, Sant Cugat del Vallès and Cerdanyola del Vallès.
