Maisons-Laffitte--an affluent commune of Paris--ended up being the perfect destination for a day trip outside of Paris; barely 20 minutes from the Arc de Triomphe! It's main attractions are the 17th-century Château de Maisons-Laffitte and horse racing track. We were thrilled to stumble upon both, in addition to ample green spaces, a traveling antique show, a tag sale at a British church, and beer, fries, and tartines at Le Cosy. I really need to go to la banlieue more often. Up next: Saint-Germain-en-Laye. Maybe, eventually, Giverny, too.
