Hopefully most of these places are well known enough that you've got a good idea where they are, and perhaps what to do there. But you don't have to be totally rigid in your destination. Think of this simply as a way to break the deadlock of indecision. Use the names in the box as inspiration, maybe researching whereabouts there is to go beforehand, or perhaps simply turning up and wandering around.
Alternatively, as a reader of this blog you might be after something a bit more challenging. Why restrict yourself to the usual tourist spots when the whole of London is available for exploration?
In which case you need this instead, my Random Psychogeography Expedition Generator.
It works the same way - first dice blue, second dice yellow - but the destinations are further flung.
Think of it as having your own random jamjar, but in grid form.
Again, don't feel constrained by the names in the boxes. If it says Croydon, it's OK to deviate to Purley. If it says Muswell Hill and Highgate, it's OK to go to Crouch End. And if you're thinking, OMG I've no idea what there is to do in Harefield or Carshalton or Erith, well, that's the point. I've learned a heck of a lot about London by simply turning up and wandering around, and you could too.
If you'd like a little more choice, use both grids. Roll the dice, and then decide whether you'd like to go to the location in the green table or the location in the pink table.
If you'd like a little less choice, toss a coin first. If you get heads, use the green table, and if you get tails, use the pink table. That could make for a properly random day out.
If today is not the day to go, maybe bookmark this page for later (or remember to click back to March 2018 at a later date).
And if you do ever go, please come back afterwards and tell us what random stuff you found. We'd love to know how you got on.
