What's the best way to see the Valparaíso street art

[ZackZuchini]

Should I just wander around on my own or is a guided tour better for finding the really unique pieces

A tour is helpful for context and hidden spots, but you can totally wander on your own on Cerro Alegre and Cerro Concepción. Just use the ascensores to get around.
