Dunedin’s street art scene isn’t hidden, it’s woven into the city’s heart. The official Dunedin Street Art Trail features over 50 murals, sprawling from the Octagon and Bath Street out to the Warehouse Precinct and Exchange area 

You can pick up a free interactive trail map at the i-SITE Visitor Centre in the Octagon, or view an online version via DunedinNZ’s site
Alternatively, the app Street Art Cities lists Dunedin too, with GPS enabled walking routes (long ~4.1 km, short ~2.6 km)
Grab a coffee and go for a wander!
