THE WALK
How it works
Four steps to get going.
01
Choose your mission
Browse the walks we've mapped before you set out.
02
Walk to the Sun
Every mission starts at a landmark. Its size sets the scale for the planets.
03
Scan the GO code
One code does it all. It looks where you are in the walk and guides you to the next stop.
04
Meet each planet
Scan the AR code when you arrive and the planet appears at true scale on the street in front of you. Take the photo, enjoy the scenery then keep walking.
