Even though markets are a year-round occurrence in France, they become so much more vibrant and enjoyable when the weather improves.
The Richard Lenoir Market, located in my favorite arrondissement, le 11ième, is known as the largest outdoor market in Paris, and has essentially everything you could want - food, flowers, furniture, clothes and even sea urchins (seriously, check out my photos below for proof.)
It's also a great place to snag some cheap jewelry (as demonstrated by my previous post discussing my slight obsession with rings.)
