We were looking for a way to see Paris that would appeal to our 4-year-old, be practical for our 6-month-old, and still be worth our time as adults. A guidebook recommended the bus tour of Paris. It turned out to be a great tip! We hopped on in front of Notre Dame and toured the city. We got out at the Eiffel Tower and at the Louvre. This was a great way to see the city. Our four-year-old had a fantastic time, the 6-month old was comfortable, and even mom and dad enjoyed the trip!
