The ride from CDG Airport into Paris is exciting. I think I still have a copy of the route we took if you need it.
Not a very good picture, but it shows our crew unpacking 4 bikes and getting them ready to start our ride into Paris. There are a lot of places where you can work on your bike in the terminal, at least there was at our terminal.
We met this guy on the way to Paris, and he said, "follow me". My wife, two daughters and I did, and he took us to a canal path that led right into Paris. We spent four days in Paris before starting our 2 month ride. What a great way to start a tour
