What to look for on site
The underground direction is fixed and the exit is separate from the entrance. Check official restrictions and physical requirements before booking, particularly if stairs are difficult for you.
How should I prepare for the Catacombs' underground route?
Choose a time slot allowing for the wait before descending. Give the underground route an unhurried visit. The official page lists 131 steps down, 112 up and an average temperature of 14°C. Consider these requirements before booking.
Are the duration and budget guaranteed?
The suggested duration of 1 h 30 is planning guidance, excluding travel and unpredictable waiting. Budget categories are editorial indications, not ticket prices. Free entry can have exceptions for exhibitions and activities; confirm the exact visit with the provider.
Sources may use French. Confirm opening hours, ticket inclusions, reservations and temporary restrictions for your exact date. For accessibility, check the entire journey from transport to entrance and facilities with the provider.
