Saint-Ouen Flea Markets: OK, so the quality’s not on a par with the Louvre des Antiquaires but that doesn’t mean that a trained eye can’t pick up a bargain or two. Along the way, you’ll find new and vintage clothes, African drums, beaded bags, gaudy mirrors, retro furniture, old videos… It will take at least an hour to wind your way past the stalls (of which there are literally thousands). Choose a sunny day to enjoy this open-air market at its best.
