If you’re going on a trip to France’s City of Lights and wondering what else you can add to your itinerary, then you should know that one of the best places to visit is the Paris Catacombs! This is one of the most popular tourist attractions in the city and the lines for it often reach outside. By booking through Klook, you can avail a skip-the-line ticket and avoid the hassles of having to wait for your turn to enter and go straight into working your way around the ossuary’s labyrinthine halls! This underground marvel is fascinating and at the same time unsettling because majority of its walls are adorned with the remains of millions of Parisians. Before you enter, borrow an audio guide from the staff so that, as you move along, you can learn about how it was constructed. A visit to this place is a must for any adventurer visiting Paris, especially for those interested in the macabre.
