Most visitors to San Francisco visit The Golden Gate Bridge or China Town, but if you are not familiar with the city’s great wall murals, you might miss them altogether. To help you discover some great street art, there’s a nice little app that’s been put together by 1:AM Gallery (named after the 1st Amendment).

The content is user-generated and each photo can take you to their exact location using the geo tags. You can even browse by location – just open the map and view works within walking distance. I especially like the feature for directions that can take you to the highest rated murals.

There’s also some murals, stencils, and graffiti from cities like Washington D.C. and London as well. If you are an urban explorer you can share your favorite murals and street art with others to view.
