Balmy Alley is located off of 24th Street in The Mission. It is parallel to Treat Ave and Harrison Street between 24th & 25th streets.
Take BART to 24th/Mission. Walk EAST (towards Capp Street or Carlos' Bar) for 5 1/2 blocks.
If you're driving- use the map below. Balmy is a small alley with many pedestrians, please park nearby and walk through- it's a much better way to appreciate the murals. (24th Street and small parts of the side streets are the only ones that are metered).
For a guided tour- check out . They offer murals tours every weekend. Well worth it.
