The Paris Catacombs are former stone quarries located beneath Denfert-Rochereau Square, housing the bones of approximately 6 million people since the 18th century; in the 2-kilometer section open to visitors, bones are arranged in geometric patterns.
The Paris Catacombs are part of an ancient quarry network extending 20 meters deep beneath the city. At the end of the 18th century, when city cemeteries were moved, bones were brought here. Today, the remains of over 6 million Parisians are stacked in orderly rows. Skulls and bones are arranged to form patterns, crosses, and heart shapes in some sections; this arrangement was made in the 19th century.
The tour takes about an hour, passing through narrow and dimly lit tunnels. The ground is gravelly, and the ceiling is low in some sections. Comfortable shoes are important. Visitors note that the included audio guide explains the city's history well, enriching the experience significantly. For those traveling alone, the dim light might be a bit eerie; some comments suggest that going in a group is more comfortable.
The site closed for renovation in November 2025 and reopened on April 8, 2026, with a renewed arrangement. Some visitors write that its new state has lost its old texture and that the price has also increased. It gets crowded at the entrance, so it is necessary to purchase a timed ticket.

Guide's Note
When to Visit?
While Paris streets are hot and crowded in summer, the underground remains consistently cool. Visitors therefore particularly recommend summer tours. To reduce queuing, it's smart to get a timed ticket for the first hours of the day. Demand is higher on weekends and school holidays.
How to Get There?
The entrance is at Denfert-Rochereau square. Metro lines 4 and 6 reach here directly, and RER B is also an option. It takes approximately 25 minutes from the Eiffel Tower. Metro services start at 5:30 AM every day; check night hours for your return.
How Much Time to Allocate?
The time spent inside the tunnels is approximately one hour. This does not include waiting in line and gathering outside. If you have a timed ticket, this duration is shortened. It can easily be fitted into a half-day Paris itinerary.
Things to Consider
The ground is gravelly, and the ceiling is low in some passages; do not choose high heels or non-breathable soles. Lighting is dim, so it may not be suitable for those with heart conditions or claustrophobia. Some visitors note that taking selfies in the area where the bones are located is considered disrespectful. It is important to remember that this is a memorial cemetery.
Photo Spots
The sections where bones are arranged to form crosses, hearts, and geometric patterns are the most photographed parts. Since the light is low, flashless shooting or the night mode of a phone camera yields better results. Tripods and large equipment are generally not allowed.
Things to Know
The site closed for renovation in November 2025 and reopened on April 8, 2026, with a new arrangement. Some former visitors write that the new arrangement creates a different atmosphere from its previous state and that prices have also increased. Remember that the entrance fee can quickly increase the total cost for families; budget in advance for large groups.
How to Add to Your Itinerary?
Denfert-Rochereau is close to Montparnasse and Luxembourg Gardens. It's a logical plan to combine a Catacombs visit in the afternoon, followed by city views from the Montparnasse Tower. Dedicating morning hours to sunnier and open-air venues and placing the underground visit in the middle of the day also works for those looking to cool down.
