urban walks
I have walked in London, Paris, Rome, Geneva, Lausanne Florence and other cities for many hours at a time. I would often walk in London until I got too tired to continue, and then I would catch the tube back to somewhere I knew, and then I’d walk some more.
I did the same in Rome and Paris. When you take the tube, or the Metro in Paris or Rome then it’s easy not to know how close places are. If you walk though. you do. That’s because you generate a mental map of the places you walk to and from. You don’t get that on the tube.
