Paris in Summer

If you are staying in Paris for the summer (or visiting) 
you can have a Seine-side holiday replete with sand, 
beach chairs, misting fountains, volleyball, and more.  
Essentially, it is a beach vacation for the Parisians 
who do not leave during the grandes vacances  
and for the city's visitors.  

The dates for 2014 are July 20th through August 20th.  
Perhaps I am mistaken but these appear to be barges of sand!
