This route is simply spilt between two central London locations -
Trafalgar Square and (near by) Waterloo Place. Apart from the stroll
around the two locations to solve the clues, there is a very short
walk down Pall Mall from one square to the other.
To make this more of a challenge if there is a group of people
participating in competition with each other, you can be strict in
allowing just 90 minutes to complete this route. That means
approx. 40 minutes for each of the two locations and allows 10
minutes to walk from one to the other.
Of course, once the route is completed, there are plenty of pubs,
restaurants, cafes etc close by, in which to meet up afterwards and
compare scores.
