The famous Champs Élysées as seen from Arc de Triomphe. This avenue is often called the most beautiful avenue in the world. Every evening that we were in Paris, we ended up at Champs Élysées. It's a marvellous place for walking, day and night. It's 2 km long, running from the Place de la Concorde to Arc de Triomphe, with shops and cafés on both sides.
