11 Bus Route

The 11 bus is absolutely great if you want to do a bit of sightseeing but not pay upwards of £20 for the pleasure.
Get on at Liverpool Street, and sit on the top deck, preferably at the front.
You’ll go past, in order:
The Bank of England
St Paul’s Cathedral
The Royal Courts of Justice
Somerset House
A lot of theatres and The Waldorf on Aldwych (if you turn your head to the right after Somerset House!)
Trafalgar Square
Horse Guards Parade
Downing Street
Big Ben
Westminster Abbey
I’d then recommend getting off at the New Scotland Yard stop and walking up Buckingham Gate to go and have a look at Buckingham Palace.
OR stay on and get off at Victoria Station if you’re heading anywhere on the train or want to get a tube.
OR stay on and you’ll go to Chelsea, via Sloane Square station and the Kings Road.
It’s brilliant, and very low priced!

Um London zu erkunden, bevor man sich die Füsse platt läuft, ist der 11er Doppeldecker Bus eine lohnende Alternative zu den Sightseeing-​Bussen. Der Preis für eine Tageskarte für Bus und U-​Bahn (7,30 Pfund) ist auch durchaus angemessen.
Ich bin von Victoria Station über Trafalgar Square, vorbei u.a. an Westminster Abbay und St. Pauls Kathedral bis Bahnhof Liverpool Street gefahren. Von dort aus habe ich mich dann zu Fuß Richtung Themse gemacht, habe die dortigen Sehenswürdigkeiten (u.a. Tower bridge) erkundet und bin dann noch weiter mit der Underground und diversen Bussen quer durch London gefahren.
Leider waren die Bus-​Touren sehr zähflüssig, da London zur Zeit eine einzige Baustelle zu sein scheint ;-(

The number 11 bus route is one of the best in London for sightseeing, if you don’t want to fork out for the more expensive tour buses (and endure their running commentaries), and generally operates at a much greater frequency.
Running from Fulham Broadway to Liverpool Street station, the route takes in a whole load of classic sights, as well as useful transport hubs such as Victoria coach and train stations, and Sloane Square, Charing Cross, Mansion House and Bank railway/​tube stations.
It was even better when they used the old Routemasters, but you still get a great view from the front of the top deck. If you go straight through, the off-​peak journey time is around an hour end to end, although most people are likely to travel between Victoria and St Paul’s.
The route starts in Fulham Broadway, and then travels the length of the King’s Road in Chelsea as far as Sloane Square, when the sights begin to really start: the Chelsea Hospital, Westminster Cathedral, Westminster Abbey, Parliament Square and the Houses of Parliament, Whitehall (passing Downing Street and Horseguards Parade), Trafalgar Square, the Strand, the Aldwych (with all its churches), the Royal Courts of Justice, St Paul’s Cathedral and the Bank of England. Not bad for a single fare of £1.
At various times I’ve used this to travel to and from work when I worked in Whitehall. The frequency in my experience tends towards the lower end (ie every 10 minutes) although it has improved in recent years. Still, it’s a great way to see lots of sights for very little cash, and if you have an Oyster card or travelcard, you can use it as a hop-​on, hop-​off service.
