Paris, Banks of the Seine
From the UNESCO description: “From the Louvre to the Eiffel Tower, from the Place de la Concorde to the Grand and Petit Palais, the evolution of Paris and its history can be seen from the River Seine. The Cathedral of Notre-Dame and the Sainte Chapelle are architectural masterpieces while Haussmann’s wide squares and boulevards influenced late 19th- and 20th-century town planning the world over.”
If you go: I usually forgo organized walking tours but on this trip, we took one through Sight Seeker’s Delight and really enjoyed it. It was a small, manageable group of 11. We were all Americans except for our guide and her friend. Our guide, Hanna, an Australian actress studying mime in Paris, was energetic, knowledgeable and entertaining. The tour took about four hours and included a stop for lunch. A cheaper alternative (the walking tour cost us 40 euro each) would be to buy any number of guide books and plan your own walk at your own pace. Another great way to see the sights on the Seine is to buy a fare on the Batobus, a ferry which loops through Paris on the Seine and allows you to get off and on at any number of stops along the way. We did the Batobus on our third day and it was a welcome change of pace from all the walking.
