Editorial Policy
This page explains how Paris Underground Tours chooses information and bookable options. We are an independent guide, not an official attraction or tour operator.
Last updated · October 2026
We publish practical guidance for travellers planning underground and archaeological visits in Paris. We aim to make choices clearer, but booking, entry, availability and refunds are handled by the provider you book with.
How we check facts
We use attraction and operator information for visitor rules, access and what a visit includes. We use transport authorities for travel information. For bookable activities, we use the booking partner’s own product data.
- Attraction or operator information takes priority for site access, rules and closures.
- Transport authority information takes priority for routes and service changes.
- Product listings take priority for the details of that specific ticket or tour.
If information conflicts or is unclear, we avoid making a firm claim. You should check the listing before booking.
How we choose and order products
We select options that help travellers compare entry, guided formats, access areas, combinations and feedback. We may place a clear standard option first, followed by alternatives with different inclusions or formats.
Commission does not decide the order. Affiliate income never buys a better placement, a stronger description or a more favourable recommendation.
Prices, ratings and reviews
Prices, ratings and review counts are starting points, not promises. They can change with dates, availability, currency, options and new traveller feedback.
We use reviews to spot repeated strengths or problems, such as meeting-point clarity or guide quality. We do not treat one review as proof, and we do not present selected quotes as the full picture.
Affiliate links and bookings
Some links go to GetYourGuide. If you book through one, Paris Underground Tours may earn a commission at no extra cost to you.
We do not sell tickets, take payment, process bookings or control availability. For a booking change, cancellation, refund or supplier question, contact GetYourGuide through your booking confirmation.
Corrections and updates
We correct clear errors when we find them. If a detail is time-sensitive, uncertain or no longer supported, we may change or remove it while we check it.
This policy is provided for transparency. It does not replace the booking provider’s terms, which govern any purchase. Your consumer rights may depend on your location and the seller’s terms.
