Once again, bots simply can’t grasp concepts like “underrated,” “unique” or “unusual,” probably because these require originality and, by definition, they can’t do that.
Some of the recommendations from GuideGeek include places like the Paris Catacombs and Père Lachaise Cemetery — two of the city’s most popular tourist attractions. We guess exploring catacombs could be unusual since not many cities have something similar but they’re a standard part of a Paris trip.
One cool recommendation was to tour the Paris sewers, which, yes, are open to the public. You can recreate the pivotal scene from Les Mis by walking around them. Don’t worry, you (probably) won’t get any sewage on you.
