When you're in Paris, a visit to the Montmartre neighborhood is a must. There are many shops, cafes, and bistros here.
Walk to the top of the Basillica and take a visit inside. It is free to enter but donations are greatly appreciated. No photographs allowed while you are in! But enjoy the beautiful architecture and stained glass windows.
Here is the best place to view the entire of Paris. On a clear day like this the view is breathtaking.
