There's a plethora of walls dripping with skilfully applied spray paint on show in these two-hour tours that start in the city centre and end in Stokes Croft. Banksy artworks feature strongly but other highlights of the city's great graffiti offering are covered too. Afterwards they run hour-long Stencil Art Spray Sessions (£12.50, Saturday and Sunday 1.45pm) where you 'get your hands on the cans', producing artworks to take home.
