Central Paris is very small. There are 20 arrondissements or neighborhoods. With the bus or metro, it's very easy to travel all over Paris in a few minutes. My favorite part of train travel within Paris is the Navigo. This is what we call our MetroCards. But instead of swiping the card like you do in New York City, here, we tap our Navigo card in order to pass through the barrier onto the platform. It's super easy and quick.
