Time Out says
You’ll find Colourscape’s colourful tunnels taking over Clapham Common once again this September. Guests must choose a coloured cape to don before venturing into the enormous labyrinth to explore nearly an acre of space while daylight casts a rainbow glow through its walls. Weekends see the addition of unusual musical performances, which really tip the experience into magical territory. During the week Colourscape is only open to the public between noon and 1pm, on weekends it is open from noon-5pm. Find out more here.
