10 a.m. - Get Hopping

If you want to hit a flea market where things are hopping, head to Porte de Montreuil. You can find everything – from car-parts to second-hand clothes – at this vast market, one of the oldest and largest in Paris. The mountains of tat may not be pretty, but sifting through the piles may unearth a treasure: in 1991, a punter reputedly bought a painting here that later turned out to be a Van Gogh worth over 2 million Euro! Go early on a Monday morning before all the good stuff is snatched up.
