One summer night in Paris, I found Tuileries Garden (Jardin des Tuileries) located betwen the Louvre and Place de le Concorde.
During summer, there is a carnival set up with Ferris Wheel, Carousel and other rides. There are food stands art exhibits and a restaurant tent to end the night with a glass of Champagne…or two.
The best view is from Place du Carrousel. Facing away from the Louvre, look down the main path of the Tuileries to the Place de la Concorde with the Egyptian Obelisk and on down the Champs Elysées to the Arc du Triomphe . . . all at the same time!
