Approximately 50% of Parisians leave Paris during the months of July and August. Another 30% arrive as tourist. So they say the City is about 20% empty compared to the rest of the year. For the poor souls who do not get to travel to the south of France or other exotic or non-exotic destinations, the City creates artificial beaches along the Seine called Paris-Plages (Paris-Beaches). Every day from 8AM till midnight, the roadways are blocked for activities and some areas are even created to look like actual beaches with sand and palm trees and all ... it's not fooling anyone but I guess it's kind of neat to be sitting on sand under palm trees staring at Notre Dame - a great view if I do say so myself. People sunbathe, relax on the edge of the river, play an abundant amount of different games, and of course lots of eating and drinking.
