Paris has a well-connected public transportation system, including buses and subways. Consider purchasing a Paris Visit Pass, a tourist pass that includes unlimited access to public transportation and discounts on many attractions. The pass starts at 35 euros for two days. Alternatively, Uber and taxis are also available but can be more expensive.
If you have more time, consider visiting the Palace of Versailles, a UNESCO Heritage Site about an hour outside Paris or the Musée d'Orsay, an art museum with an impressive collection of impressionism and post-impressionism. If you have less time, you can skip some of the attractions in the itinerary and spend more time exploring the charming Parisian neighborhoods or enjoy a romantic boat ride on the Seine River.
