Time Out says
Colourscape’s colourful tunnels are taking over Clapham Common for the thirtieth year. Celebrate by wrapping yourself in a coloured cape and venturing into the enormous labyrinth of kaleidoscopic tunnels - there’s nearly an acre of space to explore while daylight casts a rainbow glow through its walls. At weekends unusual musical performances will join the mix, really tipping the experience into magical territory.
Opening times: Weekdays 12noon to 1pm (£5 Mon-Thu, £6 Fri), weekends 12noon to 5pm (£11).
