Home to a diverse mix of celebrities, old-school French families, and a melting pot of Europeans from across the continent, Nice is unlike any other place in France I've ever visited. From its glittering beach clubs to its beautiful old town and quiet residential neighborhoods, it has a real, authentic culture all its own. While there, I kind of dubbed it the French San Diego: beachy, relaxed, full of history, and littered with yachts. It serves as the perfect starting or ending point for a trip to the French Riviera or even Provence thanks to the availability of train lines and flights within both France and abroad. Here's how to spend the perfect three days in the jewel of the south.
