How we checked licences. In France, a company that sells travel packages or organised tours must be registered with Atout France, the national tourism agency, and print its IM registration number. We looked for it on each operator's own website; several Catacombs operators are American or Italian companies selling into Paris and publish their home-country registrations instead. 1 of 6 publish one — shown above. Catacombes de Paris (official), LivTours, ExperienceFirst, The Tour Guy, Walks (WalksDevour): real, reviewed operators that don't list a number publicly; we mark them unverified rather than omit them. We excluded aggregators and booking portals, which are not operators.
Left out. Walking-tour companies that rank well on Google Maps for Paris but run no Catacombs tour were left out, as were resellers and combo sellers that do not run their own guided visits. Two tour companies with Catacombs pages were not listed because their own sites could not be read to confirm prices.
Disclosure. Direct prices and ratings are from operators' own sites and public review platforms (checked October 27, 2026). Online prices, ratings and review counts are GetYourGuide's, captured October 27, 2026; booking through those links may earn us a commission at no extra cost to you, and it never changes the order. Always confirm current price, schedule and what's included with the operator before booking. Machine-readable version (JSON)
