Quick answer: For most travellers, Viator is the best all-round site to book tours: the largest catalogue, the deepest verified reviews, a 24-hour free-cancellation rule on most products and 24/7 support. GetYourGuide is the best alternative in Europe, Klook the best for tickets and transport in Asia, and Tiqets the fastest way to buy a plain museum ticket. The rest of this ranking covers the specialists — and when each is worth opening instead.

How We Ranked Them
We scored each platform on five things that actually affect a trip: size and quality of catalogue, review depth (can you tell a good operator from a bad one?), cancellation policy, price transparency (no hidden fees) and support when something goes wrong on the day. We also weighed regional strength, because the best site for Kyoto is not the best site for Kraków. Prices for the same product are usually identical across platforms, so price alone rarely decides it.

Top-Rated Paris Tours & Experiences on Viator
1. Viator — Best Overall
Owned by Tripadvisor, Viator lists 300,000+ experiences in more than 200 countries and pools its reviews with Tripadvisor’s, which is why the Paris tours above each carry thousands of ratings. Most tours are free to cancel up to 24 hours before, there is no booking fee, and the 24/7 support team only handles experiences. Weaknesses: the Rewards credit is modest and excluded on promo-code bookings, and for pure attraction tickets a specialist is sometimes a few euros cheaper. Read Is Viator legit? and Viator vs booking direct.
2. GetYourGuide — Best in Europe
Berlin-based, with a very deep European catalogue, its own “Originals” experiences and a clean full-refund-over-24-hours rule. Reserve-now-pay-later on many tours is a plus for planners. Slightly thinner than Viator outside Europe and the biggest world cities. See Viator vs GetYourGuide.
3. Klook — Best in Asia
Hong Kong-based and unbeatable for Japan Rail passes, Shinkansen tickets, theme parks, airport trains and eSIMs across East and Southeast Asia, with constant promo codes and credits. Its three cancellation tiers need reading, and its guided-tour selection and reviews trail Viator. See Viator vs Klook.
4. Tiqets — Best for Plain Tickets
Amsterdam-based ticket specialist with instant, often venue-issued tickets and self-service rescheduling on many products. Not a tour platform, and cancellation is only possible when the venue allows it. See Viator vs Tiqets.
5. Civitatis — Best for Spain and Latin America
Madrid-based, Spanish-first, with hundreds of free walking tours and strong local coverage from Seville to Santiago de Chile. English-language depth is smaller. See Viator vs Civitatis.
6. Headout — Best Last-Minute
A curated, mobile-first platform excellent for same-day tickets and shows in major cities, and strong in Dubai. Cancellation terms are stricter and refunds depend on supplier approval. See Viator vs Headout.
7. Airbnb Experiences — Best for Intimate Activities
Relaunched in 2025 with a curated set of hosts: cooking, crafts, photography walks in tiny groups. Not for day trips or anything needing transport or tickets. See Viator vs Airbnb Experiences.
8. Trip.com — Best for China
The activities arm of a huge online travel agency, with unmatched inventory in mainland China and Hong Kong and useful bundling with flights and rail. Thin outside East Asia. See Viator vs Trip.com.
9. Musement — Best with a TUI Holiday
TUI’s activity platform, born in Milan, good for official Italian museum tickets and resort excursions coordinated with TUI hotels. Smaller catalogue and fewer reviews elsewhere. See Viator vs Musement.
10. Expedia Things to Do — Best for Package Bookers
Handy if you already have a flight-and-hotel package and want One Key rewards on a transfer or theme-park ticket. Limited tour selection and thin reviews. See Viator vs Expedia.
Which Site Should You Use?
Book guided tours and day trips on Viator. Buy plain tickets on Tiqets (Europe) or Klook (Asia) if they are cheaper, and fall back to a guided tour on Viator or GetYourGuide when the official ticket is sold out. Use Civitatis if you want Spanish-language guides, Headout for tonight’s show, and Airbnb Experiences for one memorable evening with a local. And remember that Tripadvisor’s own experiences pages sell Viator inventory — see Viator vs Tripadvisor. Destination picks: Paris, Tokyo, New York City.
Frequently Asked Questions
What is the most reliable site to book tours?
Viator. It has the largest catalogue, verified reviews combined with Tripadvisor, a 24-hour free-cancellation rule on most tours and 24/7 support. GetYourGuide is an equally reliable alternative, especially in Europe.
Which tour site is cheapest?
For the same product, prices are usually identical across platforms because the operator sets them. Savings come from promo codes (Klook, Headout) or from choosing a plain ticket over a guided visit when a guide isn’t needed.
Is it better to book tours in advance or on arrival?
For popular attractions and peak-season day trips, book in advance — the best tours sell out days or weeks ahead. Most platforms let you cancel free up to 24 hours before, so booking early costs nothing extra.
Are tour booking sites safe to use?
The ten platforms above are established companies that take payment securely, hold it until after the activity and offer refunds if the operator cancels. Always check the individual listing’s reviews and cancellation policy.
Do I need more than one tour booking site?
Often, yes. A common combination is Viator for guided tours, plus Tiqets or Klook for tickets depending on the region.
Which site has the best cancellation policy?
Viator and GetYourGuide are the simplest: free cancellation up to 24 hours before on most products. Airbnb Experiences and Civitatis are similar. Klook, Headout and Tiqets vary by listing.
