When it heats up in Paris point yourself in the direction of the Eiffel Tower and head for the grassy banks along the Fountain of Warsaw, a long basin with twelve fountains spewing water 12 meters high at appointed hours. Most dramatic are twenty powerful water cannons able to shoot water fifty meters, a great photo op. Just know when to expect the pumping jets of water. The entire site was originally the Palais du Trocadero, part of the Exposition Universelle in 1878.
