Many times during my travels I have mentioned the benefits of taking one of the ‘hop-on, hop-off’ bus tours offered in almost every major city. If visiting Paris I highly recommend taking a tour. It is a large city with so much to see and the various bus tours will take you past every major site in every neighborhood giving you the opportunity to hop-off and on whenever the urge strikes you.
The bus tours have narration which can be extremely informative and entertaining. Not only do you get a birds eye view of everything, you learn about it as you are seeing it too.
