There’s a certain kind of magic to traveling Europe by train, the way vineyards give way to mountains, how one station platform can transport you into a completely different culture. And when you’re traveling as a family, it’s even more special: no airport stress, plenty of legroom, and the thrill of watching the world roll by together. This 14-day itinerary blends the best of France and Spain, from Parisian boulevards to the sun-washed shores of the Costa Brava.
