What are the lowest Tootbus hop-on hop-off bus tour prices in Paris?

The cheapest hop-on hop-off bus tour in Paris depends less on the sticker price than on where you buy the ticket, who is travelling with you and what the pass actually includes. Tootbus‘s Paris Discovery pass is the lowest adult fare verifiable right now at €36.75 online on its official site, while Foxity displays cheaper-looking fares (from around €20) based on independent data dating from April 2024 that should be revalidated before booking. So the cheapest operator for a solo adult online may not be the cheapest for a family buying at the stop.

Quick answer: the cheapest hop-on hop-off bus tour in Paris right now

The three main operators currently display these base fares for adults: Foxity lists a fixed panoramic City Tour at around €20 and a hop-on hop-off formula at €24 (independent Paris guide, April 2024 — note that Foxity’s core product is a fixed ~2-hour panoramic loop, with the hop-on hop-off pass as a separate formula); Tootbus displays its Paris Discovery hop-on hop-off pass at €49.00, reduced to €36.75 (-25%) in online booking on its official site (adult fare, 1-3 day pass, checked at the time of writing); Big Bus Paris‘ 24-hour adult fares start from €41 on weekdays and €45 on weekends, according to a 2026 travel guide.

One rule changes everything: the displayed price is not the real price. Depending on your booking channel, your group profile and what the ticket covers, the cheapest operator can change — sometimes the ranking flips entirely.

How much each figure can be trusted varies: the Tootbus fare is an official price checked on the operator’s own booking site at the time of writing, the Big Bus fares come from an independent 2026 guide, and the Foxity fares rest on independent data from April 2024 flagged for revalidation. Official fares, when available, take precedence over independent guides — and any dated third-party figure should be rechecked on the operator’s official site before booking.

Sticker price vs real price: how online booking changes the ranking

The gap between the displayed price and the price actually paid is best documented with Tootbus. Its official site shows the Paris Discovery pass at €49.00, discounted to €36.75 online — a 25% reduction — with 5 free walking tours included (adult fare, 1-3 day pass, checked at the time of writing). That single data point, taken from Tootbus’s own booking page, shows the mechanism at work: an operator whose sticker price looks mid-range can become the lowest adult fare once the online channel is used.

Whether Tootbus’s 25% online reduction is permanent or a time-limited promotion cannot be confirmed from the fare itself — check the booking conditions on its official site before assuming the discounted rate will still apply on your travel date. The same logic applies to the other operators: Foxity and Big Bus may apply their own online-versus-on-site price differences, so the only reliable comparison is between the online fares of each operator at the moment you book, not between the brochure prices shown at the kerb.

Cheapest by traveller profile: solo, couple and family cost comparison

The cheapest operator depends on your group composition, because child policies and online adult discounts pull the ranking in opposite directions. For adults booking online, Tootbus’s €36.75 discounted fare is currently the lowest verified hop-on hop-off adult price among the three operators. For families, Foxity’s child ticket rate changes the calculation: children up to 12 years old pay €7, with one reduced-fare child per paying adult (April 2024 data, to revalidate) — children are not free, but the supplement is small.

Combining these verified elements into an indicative cost matrix (this synthesis is the article’s own analysis, built from the sourced facts above):

Read as a decision grid, the pattern is clear: for a couple or solo adult booking online, the ranking depends mainly on whether Foxity’s cheaper fare buys you the product you actually want (see the fixed-tour vs pass distinction below). For a family with children under 12, Foxity’s €7 child supplement gives it a lower verified total than two Tootbus adults online — provided the 2024 child rate still holds. Child policies for Tootbus and Big Bus were not verifiable in the sources used here, so check them on each official site before deciding.

What’s actually included: comparing value per ticket, not just price

When fares are a few euros apart, what the ticket includes should decide the comparison. Tootbus’s Paris Discovery pass includes, according to its official site, 5 free guided walking tours, a multilingual audioguide, a real-time bus tracking app, free wifi on board, an electric fleet, wheelchair access and open-top decks. Big Bus’s inclusion list could not be documented at the same level of detail from the sources used here, except on accessibility and animals: wheelchair and stroller access on Paris’s hop-on-hop-off options is generally provided via ramps on buses and boats, and dogs on leads are allowed on both Tootbus and Big Bus Paris (small dogs on laps), according to a May 2026 independent travel guide. Foxity’s included services should be confirmed directly on its official site.

Reasoning in cost per included service rather than base price: at €36.75 online, a Tootbus pass that bundles five walking tours with the bus loop costs less per activity than a cheaper fare with no extras. This value-per-inclusion reasoning is the article’s own analysis — the inclusion lists themselves remain attributed to each operator’s official site or to the independent guide cited.

Before you compare prices (and how to pay the lowest)

The « cheapest » option is not the same product depending on three distinctions you should settle before comparing any fare:

• Bus vs river shuttle. Batobus river shuttle fares are about €23 for a 1-day adult pass and €27 for 2 days, with reduced child fares for ages 4-11 and free access for under-4s, according to the Paris tourist office site. Batobus is a boat shuttle on the Seine, not a hop-on hop-off bus — a lower price here does not answer the bus question, it answers a different one.
• Fixed panoramic tour vs full hop-on hop-off pass. The gap between Foxity’s ~€20 City Tour and its €24 HOHO formula is explained by the product itself: the fixed tour lasts about two hours without the option to get off and re-board, while the pass allows unlimited boarding. A cheaper fixed ticket is not the cheapest hop-on hop-off option — it is a cheaper way to see Paris from a bus, full stop.
• 1 day vs multi-day. Tootbus’s pass covers 1 to 3 days within the same fare; Big Bus sells a 24-hour ticket as its base product. If you plan to spread your sightseeing over several days, compare the multi-day structure of each pass rather than the cheapest single-day ticket.

To pay the lowest real price for the product you actually want, four habits make the difference:

1. Book online rather than at the stop — the Tootbus example above (€49.00 displayed, €36.75 online) shows how much the channel alone can change the fare.
2. Check the child conditions for your operator and your children’s ages before buying, since family totals can reverse the ranking.
3. Match the pass duration to your real usage: a multi-day pass only pays off if you genuinely spread visits over the validity window.
4. Confirm what the ticket covers — a lower fare with a narrower perimeter (fixed tour, shorter validity, fewer inclusions) can be the wrong cheap ticket.

Once you know which product you need, the same price-discipline logic applies to the rest of the trip — for instance, when and how to book your hotel follows a similar channel-and-timing reasoning.
