Maresme is located along the Catalan Mediterranean coast and bordered, at the west, by Serralada Litoral (Catalonia's coastal mountains), which separates it from the region of Vallès Oriental. The east side of Maresme borders with Selva and the west with Barcelonès comarques. Maresme is very well connected with Barcelona and its surroundings thanks to C-32 Barcelona-Palafolls highway, N-II main road and Barcelona-Maçanet railway line.
