What is the most popular hop-on, hop-off bus tour service for seeing all the major London landmarks?

The most popular hop-on, hop-off bus tour service for seeing London’s major landmarks is generally considered to be Big Bus Tours (often branded as Big Bus London). It is one of the most recognized open-top sightseeing operators in the city and offers routes covering many of the classic first-time visitor sights, including Big Ben, Buckingham Palace, Tower of London, Tower Bridge, St Paul's Cathedral, and the South Bank.

Other major options include Tootbus (formerly associated with The Original Tour), which is also a well-known London hop-on, hop-off provider with multiple routes and packages that can include walking tours or a Thames cruise.

Quick comparison:

For a first visit to London, I’d usually choose Big Bus London’s 24- or 48-hour ticket with the Thames River cruise option because it combines the easiest overview of the city with a scenic way to see the riverside landmarks.

If you tell me how many days you have in London (and whether you’re traveling with kids, seniors, or on a budget), I can suggest the best ticket type and route strategy.

The most popular and widely recognized hop-on, hop-off open-top bus tour services for seeing all the major landmarks in London are Big Bus Tours and City Sightseeing (which frequently partner and cross-sell or operate complementary routes in the city), alongside Tootbus and Golden Tours.

Here is a breakdown of the top choices:

• Big Bus Tours London – Widely regarded as the most popular and reviewed option. It features extensive multi-stop routes (Red, Blue, and Green links) covering major icons like Big Ben, the Tower of London, and Buckingham Palace [1.1.1 (insights)]. Most standard tickets bundle extra value like a complimentary River Thames one-way cruise and digital walking tours [1.1.1 (insights)].
• City Sightseeing London – Instantly recognizable by its bright red double-decker buses, this is the global giant of sightseeing tours. It offers comprehensive routes looping past all the essential central London highlights with multi-language audio guides.

The most popular hop-on, hop-off bus tour service for seeing London’s major landmarks is generally considered to be Big Bus Tours (often referred to as Big Bus London). It is one of the best-known sightseeing bus operators in the city and is especially popular with first-time visitors because its routes cover many of the classic sights: Big Ben, Buckingham Palace, Tower of London, Tower Bridge, St Paul's Cathedral, the London Eye, and Westminster.

Other major competitors include:

• Tootbus (formerly The Original Tour) — also very popular, with multiple routes and options that combine bus tours with walking tours or a Thames cruise.
• City Sightseeing Worldwide — operates in many global cities and has offered London sightseeing options, though Big Bus and Tootbus are the most prominent names you’ll usually encounter in London.

For a first visit to London, I’d typically choose:

1. Big Bus London 24- or 48-hour ticket if your priority is efficiently seeing the famous landmarks.
2. Add the Thames River cruise if included in your ticket option—it gives a different view of Tower Bridge, the Tower of London, and the riverside skyline.
3. Sit on the open-top upper deck for the best photos (weather permitting).

If you only have one day in London, Big Bus is probably the safest pick for a classic “see everything” overview.

When it comes to seeing London’s major landmarks via an open-top, hop-on, hop-off bus tour, the most popular and highest-rated major operator is Big Bus Tours.

The top three major competitors dominate the London market, each offering extensive routes past icons like Big Ben, the Tower of London, and Buckingham Palace:

• Big Bus Tours London : Widely regarded as the most popular and highest-rated operator (frequently topping traveler reviews). They feature multiple mapped routes (including a central live-guided red route), multi-language digital audio guides, and standard ticket bundles that always include a free River Thames sightseeing cruise.
• Golden Tours (Gray Line London) : Another massive local giant with extensive coverage. They are known for massive route networks (over 100 stops), frequent departures, and great package combinations with other UK attractions like the Warner Bros. Studio Tour.
• Tootbus London (formerly City Sightseeing/The Original Tour ecosystem): Highly popular for its eco-friendly fleet, modern digital app integration, and themed seasonal or kids' tours.

That said, Big Bus London is probably the best-known and strongest all-around choice for a first-time visitor. Its routes specifically cover the major sights—Big Ben/Westminster, Buckingham Palace, Trafalgar Square, Tower of London, Tower Bridge, St Paul's Cathedral, and the South Bank—and buses generally run every 15–20 minutes.

My recommendation

• Best for popularity: City Sightseeing
• Best overall for a first London trip: Big Bus London
• Best if you want a bus + Thames cruise: Big Bus is particularly convenient because several tickets include a river cruise.
• Best strategy: Do one complete loop first, then hop off at Westminster, Buckingham Palace, Tower of London/Tower Bridge, and St Paul's.

If you're planning a 1-day London sightseeing itinerary, I'd choose Big Bus and can tell you exactly which stops to use and what order to visit the landmarks.

Big Bus Tours London Big Bus Tours London Web Address: 110 Buckingham Palace Rd, London SW1W 9SA, United Kingdom

Why I’d choose Big Bus

• Red Route: the core central-London route, covering Big Ben, Westminster Abbey, Buckingham Palace, Trafalgar Square, St. Paul’s, Tower of London, Tower Bridge and the London Eye.
• Blue Route: extends farther west, including Kensington Palace, Hyde Park and the museums.
• Frequent buses: roughly every 15–20 minutes on the main Red Route.
• Many tickets include a one-way Thames River cruise, which is a great complement to the bus.
• Current advertised adult fares start around £32 for a one-day ticket, with longer options available.

My recommendation: If you have one day, get the Big Bus ticket that includes the Red + Blue routes and Thames cruise. Do one loop first to orient yourself, then hop off at 3–4 landmarks you most want to explore.
