You see them everywhere. Those bright, cherry-red double-deckers lumbering past Big Ben while tourists snap photos from the open top. It’s the classic postcard image of England. But honestly, if you just hop on the first one you see without a plan, you’re probably going to spend half your afternoon stuck in gridlock near Piccadilly Circus, wondering why you paid £35 to look at the back of a delivery van. A London red bus tour is actually a brilliant way to orient yourself, but only if you know which route to pick and when to actually get off the bus.
London is huge. Navigating the Tube is fine for getting from A to B, but you see absolutely nothing but tiled walls and dark tunnels. Taking the bus lets you actually piece the geography together. You start to realize that Covent Garden is surprisingly close to Leicester Square, and that the "Walkie Talkie" building looms over the Tower of London in a way that feels slightly surreal.
The Reality of the Big Three Operators
When people talk about a London red bus tour, they usually mean the Hop-On Hop-Off (HOHO) services. There are three main players: Big Bus, Tootbus (formerly The Original Tour), and City Sightseeing.
They all follow roughly the same paths. You’ve got the "Red Route" which usually covers the heavy hitters like Westminster Abbey, the London Eye, and St. Paul's Cathedral. Then there’s often a "Blue Route" that wanders out toward Kensington Palace and the museums in South Kensington. Big Bus tends to have the most frequent service, which matters when you’re standing in the rain at a stop near Marble Arch. Tootbus has leaned heavily into the "electric" angle lately, which is a nice touch if you care about the city's air quality—and you should, because sitting behind a diesel engine in London traffic isn't exactly a spa day.
Don’t expect a fast ride.
Seriously.
If you have a dinner reservation in 30 minutes, do not get on a tour bus. These things move at the speed of a tired snail during peak hours. The value isn't in the speed; it's in the vantage point. Being twelve feet up gives you a completely different perspective on the architecture. You’ll notice the stone carvings on the tops of buildings that pedestrians on the sidewalk never see.
Is the Live Guide Worth It?
Most buses now use pre-recorded audio commentary. You plug in those cheap plastic headphones and listen to a voice tell you that "the Great Fire of London started in Pudding Lane in 1666." It’s fine. It’s educational. But if you can find a bus with a live guide—usually more common on the Big Bus "Red" lines—grab it.
A live guide makes a massive difference. They’ll point out where a famous actor lives or mention that the scaffolding on a certain building has been there for three years. They add flavor. They also know when to stop talking and just let you look. Pre-recorded audio is relentless. It doesn't care if you're stuck at a red light for five minutes; it just keeps blabbing.
The Secret "Cheap" Alternative
I’ll be blunt: the official tours are expensive. If you’re a family of four, you’re looking at over £100 easily. If you want the "tour" experience without the price tag, you use the public Transport for London (TfL) buses. Specifically, Route 11 or Route 15.
Route 11 is legendary among locals. It starts near Liverpool Street and winds past St. Paul’s, Fleet Street, the Royal Courts of Justice, Trafalgar Square, and Westminster. It’s basically a London red bus tour for the price of a standard £1.75 fare. You don’t get the open roof, and you don’t get the commentary, but you get the exact same views.
The downside?
Public buses are packed.
You might end up standing next to a guy carrying his groceries instead of sitting comfortably on a leather seat. But if you manage to snag the front seat on the top deck of a Route 11, you’ve won the London lottery.
The Heritage Route 15
If you want the old-school vibe, look for the Heritage Route 15. Most London buses are modern, accessible, and—let's be honest—a bit boxy. But TfL still runs a few of the old "Routemasters" on a short stretch of Route 15. These are the ones with the open platform at the back where you can (theoretically, though not legally) jump on and off while it's moving. They represent a London that barely exists anymore. It’s loud, it’s bumpy, and it’s wonderful.

Timing Your Trip to Avoid the "Traffic Trap"
The biggest mistake people make is starting their tour at 11:00 AM on a Saturday. That is peak chaos. You will spend more time looking at the bumper of a black cab than you will looking at the Tower Bridge.
- Go early. The first buses usually start around 8:30 or 9:00 AM. If you’re on that first bus, the city is quiet, the light is better for photos, and you can actually get through the West End without losing your mind.
- Avoid 3:30 PM to 6:30 PM. This is the "School Run" and "Rush Hour" combined. It is a stationary nightmare.
- Night tours are underrated. Seeing the city illuminated is spectacular. The Houses of Parliament look way more imposing at night. Most companies offer a specific "Night Tour" that isn't hop-on-hop-off, but a solid loop. It’s usually cheaper and way more chill.
What Most People Miss
People get so focused on the "Big 5" sights that they ignore the smaller details. When your London red bus tour passes through the City of London (the financial district), look for the "Dragons." There are silver dragon statues marking the boundaries of the City.
Also, pay attention to the pubs. You’ll pass hundreds of them. Look for The Sherlock Holmes near Charing Cross or The Yeoman Warder near the Tower. The history of London is written in its pub signs as much as its cathedrals.
Weather Realities
It’s London. It will probably rain.
The top decks of the tour buses have a covered section at the front, but if it starts pouring, everyone dives for those seats. If you’re stuck in the open section, you’re going to get soaked. Most companies provide thin plastic ponchos. They are useless against a real British downpour. Bring a proper waterproof jacket.
On the flip side, on the three days of summer London actually gets, the top deck becomes an oven. There is no shade. Wear sunscreen. I’ve seen tourists come off a bus looking like boiled lobsters because they didn't realize how strong the sun is when you're sitting on a slow-moving vehicle for two hours.
Navigating the Hop-Off Part
The "Hop-On Hop-Off" concept sounds great in theory. In practice, it can be a pain. If you hop off at a popular spot like the London Eye, you might find a massive queue when you want to get back on. Sometimes three full buses will pass you before there's space.
My advice?
Pick two or three "must-see" stops to hop off at. Don’t try to do ten.
- Stop 1: The Tower of London. Give yourself at least three hours here. It’s worth every penny.
- Stop 2: Westminster/Big Ben. Get off, walk across the bridge, get your photos, and maybe walk through St. James's Park to Buckingham Palace.
- Stop 3: South Kensington. If you like museums (V&A, Natural History, Science), this is your spot.
If you try to hop off at every single landmark, you’ll spend your whole day waiting at bus stops. That’s a waste of a holiday.

A Note on Accessibility
Modern London buses are surprisingly accessible. They have ramps and dedicated spaces for wheelchairs. However, the vintage Routemasters are a nightmare for anyone with mobility issues. If you are traveling with a stroller or a wheelchair, stick to the main tour operators or the standard TfL fleet. The tour operators are generally very good at assisting, but the top deck is only accessible via a very narrow, winding staircase. If you can’t do stairs, you’re stuck on the bottom deck, which sort of defeats the purpose of the "view."
Expert Strategy for 2026
With the recent changes in London's Low Emission Zone (ULEZ) and the pedestrianization of certain areas around the Strand, bus routes have shifted slightly. Always check the operator's app before you head out. These apps are actually useful—they show you exactly where the buses are in real-time.
Also, check if your tour ticket includes a river cruise. Many of them do.
The Thames Clippers (Uber Boat) or the specific tour boats are a fantastic way to see the city from the water. Taking the bus one way and the boat back is the pro move. It breaks up the day and gives your legs a rest from the constant vibration of the bus.
Essential Kit for Your Tour
- A portable power bank. Using GPS and taking 400 photos of the Shard will kill your battery by lunch.
- Your own headphones. The ones they give you are itchy and sound like they're underwater. Most buses use a standard 3.5mm jack.
- A physical map. Yes, use the app, but having a paper map helps you see the "big picture" of the route when the sun is glaring on your phone screen.
- Water. Buying a bottle of water in Central London can cost as much as a small car.
Actionable Next Steps
To get the most out of your London red bus tour, start by downloading the "Citymapper" app alongside whichever tour operator you choose. Citymapper is far superior to Google Maps for London transit and will help you find the nearest tour stop if you get turned around.
Book your tickets online at least 24 hours in advance to save about 10-15% off the walk-up price. Aim to arrive at the starting point (usually near Victoria or Green Park) by 8:45 AM. Start on the "Red" line to hit the major historic landmarks while your energy is high, then switch to the "Blue" line in the afternoon if you want to see the posh residential areas of West London. If the traffic looks gridlocked on your app, don't be afraid to abandon the bus and walk for a bit—London is a very walkable city, and sometimes the best sights are the ones you find in the alleys between the bus stops.
