Biking Around the Ile de France
Paris has more history in one block than most other cities have in the entire metro area -- but don't limit yourself to the center. Instead, meander through the entire Ile de France region, where not only Paris, but also cities like Versailles are located. To experience the full breadth of the area, which is a mixture of medieval, baroque and modern historical landmarks, book a bike tour of the city, which costs as little as $40 a day per person.
