Now that Macron has backed off on the fuel tax hike, I would think the protests are subsiding but I expect it changes from day to day. Best to do some internet searching before you go. One possibility if you do decide to go and it is still closed is to visit other parts that will be festive like rue des Abbesses and Sacre Couer in Montmartre, the Place de Vosges and rue de Rivoli on the Right Bank and the Boulevard st Germain on the Left,
