At night, Paris lights up. Its nickname 'City of Lights' then makes sense. You will be delighted passing under the magnificent bridges Alexandre III, Pont Neuf or Pont des Arts, you may differently watch the emblematic Notre Dame, Orsay Museum, Conciergerie, City Hall and of course the Eiffel Tower. The dinner cruise on the Seine is a unique experience.
It is totally worth it. The food was delicious. The service was impeccable. The views were stunning.
