Graffiti Alley is exactly what it sounds like - about 90% of this alley way is covered in legit and classic graffiti style art. This isn't a spot for those looking for murals and walls found in other cities - ie. Wynwood Walls (Miami) or Clarion Alley (San Fran) but there's still plenty of beautifully colorful art to enjoy.
The walk will take you about 30 minutes or so... and don't forget to wander down the side streets coming off the alley - there's some great art work on those little streets too.
