A double-decker is the cheapest observation deck most cities own. For the price of a normal bus ticket you get a moving grandstand: rooftops, harbour bridges, cathedral spires, laundry lines, back gardens. The catch is that not every double-decker route deserves your afternoon. Some are commuter workhorses that happen to be scenic; some are purpose-built tours with commentary and a steeper price. Knowing the difference saves you money and a wasted seat.
London: Two Routes Worth the Fare
London runs double-deckers the way other cities run taxis, so the smart move is to pick a route rather than a tour. Route 24 (Pimlico to Hampstead Heath) is the classic: Westminster Abbey, the Houses of Parliament, Whitehall, Trafalgar Square, then north through Camden and up the hill to Hampstead. End to end it takes about an hour in light traffic and closer to ninety minutes at rush hour. It runs around the clock, which makes it a decent late-evening ride when the streets empty out.
Route 88 is the better choice if you want Regent Street and Oxford Circus without changing buses, and it finishes near Parliament Hill with its skyline view over the city. Fares are flat, contactless, and cash-free, with a daily cap once you've taken a few journeys. If you're in town in December, ride after dark: the Regent Street and Oxford Street lights look far better from the top deck than from pavement level.
Berlin: Line 100, the Accidental Sightseeing Bus
Berlin's BVG line 100 is the bargain of this list. It runs from Zoologischer Garten through the Tiergarten past the Victory Column, along Unter den Linden, past the Brandenburg Gate and Museum Island, and finishes at Alexanderplatz under the TV Tower. Most departures are double-deckers, and the whole trip takes roughly half an hour without traffic.
You pay a normal city fare — a single ticket or a day ticket, not a tour price. Sit upstairs on the right if you're heading east toward Alexanderplatz, and you'll catch the best angles of the Tiergarten and the government quarter. Spring through early autumn gives you the longest daylight; a December ride past the Christmas market lights is its own reward.
Hong Kong: Two Very Different Kinds of Spectacular
Hong Kong rewards anyone willing to use ordinary buses. KMB route 15 climbs from Central, near the Star Ferry, up to The Peak — about fifty minutes of tight turns, hillside apartments and glimpses down into the harbour. It's a fraction of the price of the tram or a taxi, and the top deck gives you the view the tram can't.
For something entirely different, take Citybus 6, 6X or 260 from Central to Stanley via Repulse Bay: beaches, bays and a long run along the south side of the island. Route 9 from Shau Kei Wan to Shek O is the connoisseur's pick, with a narrow cliffside stretch that double-decker drivers handle with unnerving calm.
October to December is the season to plan around: clear, dry, and cool enough to enjoy an open window. Summer brings humidity and the possibility of typhoons, when services can be suspended at short notice.
Cape Town and Sydney: When the Coast Does the Talking
Cape Town
City Sightseeing Cape Town runs open-top double-deckers on a red city loop and a much longer blue peninsula route that heads south toward Cape Point, stopping near the cableway and — whenever the pass is open — along Chapman's Peak Drive. The peninsula run takes the better part of a day, so treat it as an outing rather than a ride. The dry months from October to April are the safest bet; the summer south-easter can make the open top bracing, and winter and spring sometimes bring whales close enough to spot offshore.
Sydney
Sydney's hop-on hop-off service crosses the Harbour Bridge and connects the city with Bondi, which is the single best reason to take it. The full loop runs a couple of hours with traffic. September to November and March to May give you warm days without the worst of the summer sun — and if you do ride in January, the lower deck is not a defeat.
Hop-On, Hop-Off: New York, Dublin, Belfast
These are tours rather than transport, and you pay accordingly. In New York, the downtown loop covers Times Square, the Empire State Building, the Brooklyn Bridge approaches and the Battery, where you can see the Statue of Liberty from the waterfront. Dublin's service links Trinity College, St Patrick's Cathedral and the Guinness Storehouse with live commentary that is often the highlight. In Belfast, the city tour covers the murals and the shipyard district around Titanic Belfast — the sections most visitors would not otherwise reach on foot. Tickets are usually valid for 24 or 48 hours, so buy one only if you'll genuinely hop off more than twice.
The Comparison at a Glance
- Cheapest and most local: London 24 and 88, Berlin 100, Hong Kong 15 and 6.
- Best for a single unbroken view: Berlin 100 (about 30 minutes) and Sydney's Harbour Bridge crossing.
- Best half-day commitment: Cape Town's peninsula route.
- Best in poor weather: any enclosed double-decker — London, Berlin, Dublin.
- Best season overall: late spring and early autumn almost everywhere; December for lights; October to December in Hong Kong.
Riding Well: A Few Practical Notes
- Ride against the commuter flow. Mid-morning and early afternoon on weekdays, or Sunday mornings, give you empty upper decks and clearer views.
- Take the front seats upstairs if you can, but don't sprint for them — the view from the second row is nearly as good and far less exposed on a wet day.
- In left-hand-traffic cities, the left-hand upstairs seat is usually closest to the buildings; in right-hand-traffic cities, the right. Swap sides on the return leg.
- Keep your ticket or card handy for inspectors, and don't rely on paying with cash — several of these cities are card-only on board.
- Check the operator's site the morning you travel for diversions, roadworks and seasonal timetable changes, especially on coastal routes.
A last piece of advice: don't try to do two of these in one day. The pleasure of a scenic bus route is in the slowing down, the half-heard conversation behind you, and the moment a city suddenly arranges itself below the window. Pick one, get a seat upstairs, and let it run its length.
