The most popular and best-known choice is Big Bus Tours London. It’s probably the one I’d recommend for a first-time visitor who wants to see the major landmarks with minimal planning.
Why Big Bus stands out:
My pick: If you have one full day, I'd get the 48-hour Essential Ticket if the price difference is reasonable. It includes the hop-on/hop-off buses, Thames cruise and walking tours, giving you more flexibility than trying to cram everything into one day.
If you tell me how many days you have in London, I can also give you the best hop-on/hop-off route and exactly which stops to use for the major sights.
The most popular and widely recognized hop-on, hop-off open-top bus tour services in London are **Big Bus Tours** and **City Sightseeing / Golden Tours** .

If you want the most popular, straightforward choice for a first-time London visit, I’d go with Big Bus Tours London.

While these buses are unbeatable for a low-stress overview or managing jet lag, Central London traffic can crawl . If your goal is purely traveling from point A to point B quickly, regular Transport for London (TfL) red public buses (like the historic Route 11 or 24) or the Underground will beat the tour buses every single time for a fraction of the cost. Use the hop-on, hop-off service for the open-top panoramic experience and the recorded audio commentary, not as an efficient daily transit replacement. [1][2]
If you'd like, let me know:
I can help you decide if a 24-hour pass is enough or if you should bundle it with other attractions like the London Eye.

If you want one hop-on, hop-off service to see the major London landmarks, I’d pick Big Bus Tours London.
It’s probably the best-known and most established choice, with extensive coverage of central London. Its routes pass close to the big sights including Buckingham Palace, Westminster/Big Ben, the London Eye, St Paul’s Cathedral, Tower of London, Tower Bridge, Trafalgar Square and Piccadilly Circus. It also offers tickets that include a Thames River cruise.
For a first visit, I'd get a 1-day Big Bus ticket with the Thames cruise. The cruise is particularly useful because London's landmarks are spread along the river, and it gives you a different perspective without adding much walking.
One caveat: recent 2026 reviews of Big Bus mention crowding and occasional long waits, so I wouldn't rely on it for getting to a time-sensitive attraction reservation.
If you tell me how many days you're spending in London, I can also tell you whether Big Bus, Tootbus, or City Sightseeing is the best value for your specific itinerary.
The most popular and widely recognized hop-on, hop-off bus tour services for seeing major London landmarks are **Big Bus Tours**, **Golden Tours** , and **Tootbus**.[1] Among them, **Big Bus Tours London** is generally considered the largest and most popular global operator, boasting the highest volume of reviews and…

The most popular and best-known choice is Big Bus Tours London.
It’s particularly good for a first visit because its open-top double-decker routes cover the major sights, including:
Big Bus currently operates Red, Blue, and Green routes, with the main Red Route running roughly every 15–20 minutes.
For a tourist who wants to see the major landmarks without figuring out London's transit system, I'd choose Big Bus. Its 48-hour Essential ticket is especially appealing because it includes the hop-on/hop-off bus, a Thames River cruise, and three walking tours.
City Sightseeing is the main alternative and is also a substantial operator, with three routes and 45 stops.
If you tell me how many days you'll be in London (e.g., 1, 2, or 3), I can recommend the best bus ticket and exactly where to hop on/off to see the major sights efficiently.
