Along the quais

The Seine River runs right through the center of Paris, and long stretches of it are lined with pedestrian walkways.  During the day those walkways are much less congested than the sidewalks at street level, except for the occasional group of people queuing for a tour boat.  At night when the weather is nice, the banks are full of picnickers.

The city has recently renovated stretches of both river banks, adding cafés, picnic tables, floating gardens, and even a skateboard ramp.  My favorite path is along the left bank and runs from the Jardin des Plantes toward the center of the city.  It is our preferred spot for picnics, and we've spent many evenings taking that path to Île Saint-Louis for some Berthillon ice cream.
