HiddenCity offer various treasure hunt style tours of various cities, including a number around central London. The idea is that you book online giving the emails and mobile numbers of team captains and then, within 28 days, follow the simple instructions to begin your hunt.
We had two teams, one captained by the best man (me) and one containing the groom. All the clues are sent by text message and so HiddenCity know exactly when you started and when you finish, so there can be a winner.
All of us in both teams were Londoners, but we did the 'Hidden Places, Open Spaces' hunt and were taken to some really interesting places that none of us had been to before.
Helpfully we were taken to a place (I won't name it because it's an answer to one of the clues) where there were toilets, and the hunt ends up at a family-friendly bar.
In all it took each team about two hours to complete.
In case you're wondering, of course the groom's team won.
