Looking for a truly Parisian way to celebrate Halloween? Consider the Catacombs for a spectacularly spooky option. And not just for kids. At the start of the 83-step descent—20 meters below the city, under the metro and the sewer systems—a sign warns: “Tour could make a strong impression on children and people of a nervous disposition.” (Not to mention the lack of toilets along the 1.7km hike through the tunnels.) Be prepared for face-to-face encounters with skulls and artful arrangements of shinbones and femurs.

The network of subterranean tunnels and rooms is located in what were Roman-era limestone quarries. Near the end of the 18th century, as churchyard cemeteries overflowed epidemics and disease overran the city, the quarries were discretely converted into a mass tomb.

Meet the Parisians

If the bones of six to seven million Parisians lining the walls don’t make you shiver, the temperature may (long sleeves are recommended). Under the drips from the moist and humid air, the path is narrow, uneven, and often slippery. Gaping holes in the walls allow you to peek at the tunnels barred to the public (See Feature). A flashlight can be helpful, particularly with young children, because while the paths are lit, there are deep shadows in some places.

Make sure to get a picture at the entrance as flash photography is not allowed in the tunnels. Bringing back souvenirs is forbidden: there is a 60 € fine for the removal of bones!

Open Tuesday to Sunday 10am to 4pm. Adults 7€, students 3.50€ (free under 14).
