Colourscape is celebrating its 25th birthday at 2014's event on Clapham Common, which makes this year an even more special chance to visit its colourful tunnels in what must be the closest thing to being swallowed by a scene from 'Yellow Submarine'. Guests must choose a coloured cape 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. This year's commission, 'Pied Piper' (September 21, 1pm-5pm), will involve a journey through the maze in the company of a children's choir, with guests invited to join in the action as it unfolds. Off-site performance, 'Music of the Spheres', takes place inside a giant inflatable ball on the common's Long Pond (September 18, 7.30pm).
Naturally children will have a whale of a time, and weekdays are devoted mainly to colour and music workshops, with public access only available between noon and 1pm.
