Engulfing the Porte de Clignancourt area at the northern edge of the city, this claims to be the largest antiques market in the world. Split into 15 specialty markets, this sprawling mini-city is visited by thousands of visitors each weekend (also open Mon). Although it was once a bargain-hunter’s dream, prices now often rival those of regular antiques dealers. Still, hardcore browsers will get a kick wandering through the serpentine alleyways of this Parisian medina and may turn up a treasure. Note: Beware of pickpockets. Also, to avoid the tatty markets surrounding Les Puces, get off at Métro Garibaldi.
