Did a very broad siteseeing tour of Paris today. Mixture of Metro and walking: we walked 26.17 km. Looked at many of the popular landmarks (not all of them — can’t see Paris in a day), but I think my favourite parts were walking the quieter back streets, away from the crowds.

Wow, that’s a LOT of walking! But definitely the best way to see a city, I think (along with public transport, as you also used 😄). You can get a good general feel of a city pretty quickly that way, even if you don’t have the time to explore it in real depth.
