Dressing for the Catacombs requires planning for the unique underground environment. Because the tunnels are 20 meters deep, the weather inside does not change. Your comfort depends on bringing the right layers and footwear.
Is it cold inside the Paris Catacombs?
Yes, the temperature remains a constant 14°C (57°F) year-round.
The tunnels also have high humidity. You should bring a light sweater or jacket. Even if it is hot above ground in July, you will feel chilly during the one-hour tour. The cool air hits immediately after you descend the 131 entry steps.
What kind of shoes should I wear?
Wear flat, comfortable walking shoes or boots.
The floor is made of uneven dirt and stone. Ground surfaces can be wet and slippery due to the high humidity. You must climb down 131 steps to enter and climb up 112 narrow spiral steps to exit. High heels or dress shoes make the 1.5-kilometer walk difficult and dangerous.
Is there an official dress code for the Paris Catacombs?
There is no formal dress code, but strict bag rules affect your outfit.
You cannot bring suitcases, large bags, or motorcycle helmets inside. Your bag must measure under 40x30x20 cm. If you wear a small backpack, you must wear it on your front or carry it in your hand. This prevents you from bumping into the fragile bone walls.
Do I need weather gear for the Paris Catacombs?
You might need a raincoat or umbrella for the entrance line.
Part of your wait may take place outdoors before you scan your digital ticket. Check the Paris weather forecast before you go. Large umbrellas are banned inside, so bring a small, collapsible umbrella that fits inside your small bag.
What else should I pack for the tour?
Bring a water bottle and a fully charged power bank.
You can drink water while waiting in the outdoor line. However, eating and drinking are strictly prohibited inside the tunnels. A power bank helps keep your phone charged, as taking photos in the dark underground drains batteries quickly.
