Your next stop will be the Catacombs of Paris, but make sure you buy tickets online to avoid the 3 hour long waiting time. The tour takes about an hour and isn’t for those who get easily frightened by the sight of thousands of real human bones. Once you are finished take the train to one of the Laduree’s shops or restaurants and indulge in the world’s best macarons. These sugary delights come in more flavors than you could possibly dream of coming up with. Thanks to Pinterest and Instagram macarons have become very popular among dessert lovers.
