Parklands walk is a former railway track that became a popular path for joggers and dog walkers. It runs from near Highgate Station (entrance off of Holmesdale Road) to Finsbury Park.
From Old Street station you can walk down Great Eastern Street towards Brick Lane, ducking down Rivington Street, Curtain Road and Redchurch Street en route. Check out the walls by Village Underground
The bottom of Trellick Tower is probably the best. It’s a relatively large space with high walls, where you can check out work by talented writers such as Vibes and Roids.
If you live or work in Cardiff you can get a free unlimited pass. Just get a photo and council tax bill and pop to the ticket office :)
