How tight the Paris Catacombs feel 20 meters down
The Paris Catacombs are not a cave you crawl through, but they are a long tunnel 20 m under the city with one way out at the far end. For most people that feels fine after the first few minutes. Below we cover how narrow and low it gets and who the listings advise to stay above ground, followed by what helps if you feel uneasy.
How low and narrow the galleries get
Most of the route is a corridor roughly as wide as a hotel hallway, with a rough limestone ceiling. In many stretches an adult stands upright with room to spare.
In some places the ceiling drops, and a tall visitor bends the head for a few steps. The galleries also narrow between the walls of bones, so passing another group means turning sideways.
A few chambers open out a little around pillars or carved features, and these give you a moment to breathe and look around. They come at intervals, so the tight stretches never last very long.
The spiral staircase at the start is the tightest moment for many people. It turns and turns for 130 steps, and you cannot see the bottom until you reach it.
One way in, one way out
Nervous visitors find this part hardest to accept. The route is one-way, with about 1.5 km (1 mile) from the entrance stairs to the exit stairs, and there is no door halfway along.
If panic sets in, you either walk back against the flow or keep going to the exit. Nobody can lift you out quickly from the middle.
Knowing this in advance helps more than anything else. People who panic underground are often those who expected a museum with side doors and found a tunnel instead.
A guided group takes about 1.5–2 hours, the self-guided ticket about 1 hour. Our walk-through of the route describes each stretch, so you know in advance how far the next turn is.
Cool air and a wet, uneven floor
The air stays at about 14 °C (57 °F) in every season. After a warm street it feels cool at first, then pleasant once you are moving.
Water drips from the ceiling in places and the floor can be wet. The ground is packed earth and stone, uneven in spots, so watching your feet takes some of your attention away from the walls.
The lighting is dim but steady, with lamps along the walls and on the pillars. As far as the listings and visitor photos show, the public route is never in darkness.
Who the listings tell to stay above ground
The tour listings are blunt about this. They say the visit is not suitable for wheelchair users or people with mobility impairments. Several add heart or breathing problems to the list.
Our pick, Memories France, lists claustrophobia itself as a reason not to come. On top of the steps and the lack of a lift, the self-guided ticket also warns off pregnant women.
- Wheelchair users: no lift and 242 steps in total, so the visit is not possible
- Mobility problems or bad knees: the 112 steps up at the end are the test
- Heart or breathing problems: the listings advise against it
- Diagnosed claustrophobia: take the warnings seriously and skip it
- Mild unease in crowds or lifts: many such visitors go and are fine
Why a small group feels calmer
The standard route can hold about 200 visitors at once, and at busy times the galleries fill. Being pressed between strangers in a narrow tunnel is what makes most people uneasy.
A small group with a guide moves at its own pace and stops where there is room. On Memories France's restricted access tour at ~$211, no more than seven people share the guide, who sets the rhythm instead of the crowd behind you.
The catch is honest enough. That same listing says the tour is not for people with claustrophobia, so it suits mild nerves, not a phobia. It also costs more than four times the ticket, as our price breakdown shows.
Seven people, one calm guide
About 2 hours with Memories France, with fast-track entry included. A few rooms behind gates closed to the public are on the route. 4.9 from 530+ reviews on GetYourGuide.
Tips for nervous visitors
Book the first slot of the morning, when the galleries are emptiest. Our guide to quiet times covers which days and hours draw the smallest crowds.
If you would rather go at your own speed, the self-guided ticket lets you walk the route in about an hour without waiting for a group. The trade-off is that nobody is beside you who knows the way and the distance left.
Tell your guide at the start that you feel a little anxious. Guides on these small tours have seen it before, and a quiet word lets them keep you near the front with space around you.
- Eat something and drink water beforehand, since low blood sugar makes nerves worse
- Wear a layer you can open, so you neither shiver nor overheat
- Breathe slowly on the spiral stairs and count the steps down
- Look along the gallery rather than up at the ceiling
- Walk with someone who knows you might want to stop
A good test before booking is the metro. If a crowded train between stations bothers you a little but you cope, the Catacombs usually feel similar. If you avoid the metro altogether, think twice.
Deciding before you pay
Most listings on GetYourGuide offer free cancellation up to 24 hours before, so booking now still leaves you free to change your mind the evening before. Check the terms on your chosen listing, since they vary.
Groups with children should read our family guide as well, since the same narrow passages affect them. For a sense of the place before committing, our history of the old quarries explains what you will be walking through.
