Once you’re inside the walled city, it’s small enough to simply walk around. There are only a few streets on which cars are able to drive (and only if they are small cars). Be aware that the City of San Marino is quite vertical, making it potentially difficult for those with mobility issues to climb the switchback cobblestone streets. However, there are elevators scattered throughout town that allow easier movement up and down the city.
Outside of the capital, walking is not so easy. San Marino is the only country in the world with more vehicles than people, and it shows—sidewalks are inconsistent at best, especially when going between towns. However, there is a shaded stone path, Costa dell’Arnella, between the City of San Marino and Borgo Maggiore.
San Marino public transport comprises 8 local bus lines entirely within San Marino. There is a regular bus service between Rimini (map) and the city of San Marino.
