Vallès Occidental, Administrative division in Barcelona province, Spain
Vallès Occidental is an administrative region in Barcelona province situated between lowlands and mountain ranges including the Sant Llorenç de Munt massif. The territory encompasses around 23 municipalities and connects to Barcelona via multiple transport networks.
The region was created in 1834 as an administrative division through the split of Vallès into two districts based on the legal boundaries of Terrassa and Granollers. This division shaped the boundaries and structure that exist today.
The region is shaped by two main cities, Sabadell and Terrassa, each bringing different architectural styles and industrial traditions to the area. Both places define how the territory looks and feels today.
The region is well connected by public transport, particularly through the Metro del Vallès and several motorways to Barcelona. Visiting requires little planning since access from the city is straightforward.
The area contains several nature reserves and remains an important place for local forestry and green spaces despite its proximity to Barcelona. This balance between development and nature makes the region distinctive.
