Train maps (Metro, FGC and Rodalies)
My favourite train map is this one. It literally includes everything running on rails (even Tram lines). In shaded green, you can see Zone 1, meaning Barcelona itself, plus some other stations you can go to without leaving the first zone. Metro is represented with thinner lines, whereas regional services are shown with heavier lines.
If the previous map is too crowded for you, you can try with this one. It only shows Zone 1 (Barcelona), and regional and suburban services are combined into generic gray lines to avoid cluttering, so it’s ideal if you only plan to use Metro.
Attention: nomenclature of train lines is a bit messy. You can be tempted to assume that numbers indicate the “direction”, and the letter in front indicates the type of service, but this is not true. There is no relationship between numbers in different operators. For example, lines L1, T1, S1 and R1 are completely different and will take you to opposite directions. L1 is the Metro line 1 (operated by TMB), S1 is the suburban line 1 (FGC), and R1 is the regional line 1 (operated by Rodalies/RENFE). T1 is the tram line 1. Try to locate them on the map so you can see that they have nothing to do with each other.
Some transfers will take longer than others. For example, transferring at Passeig de Gràcia between L2 and L3 takes ages! This beautiful map (credits to UPF and PTP) includes transferring time between services and also travel time between stops.
Bus maps
The official bus map can be found here, but I find it truly confusing and crowded. Unless you need to take a bus to a remote neighbourhood, I would suggest sticking to the new bus lines. As it has been explained in the Bus webpage, the new bus lines are easier to understand, faster, better equipped and more frequent. You can virtually get anywhere using the new bus lines.
