Paris has a very efficient public transportation system, including a metro and buses that operate throughout the city. A single ticket costs €1.90, and a pack of 10 tickets, known as a carnet, costs €14.90. Taxis, Ubers, and bike rentals are also available. It's important to remember that peak travel times, such as rush hour, can significantly increase travel time.
If you have more time, consider visiting the Palace of Fontainebleau, which is known for its ornate interiors and serene gardens. If you have less time, skip Montmartre and spend more time at the Eiffel Tower and the Louvre Museum. To avoid crowds, visit popular attractions early in the morning or late in the evening.
