Londoner Buses - Heritage Route A
Londoner Buses run a number of Routemaster buses on a circular route starting and finishing at Waterloo station. They run every 15 minutes and, subject to traffic conditions, the journey usually takes 45 minutes. You can buy a hop on / hop off ticket for £5 and that lasts you all day.
I took a ride recently and decided to film the journey from the downstairs front seat. I couldn't sit upstairs as the seats were occupied when I got there.
If you're in London and have a spare hour, I'd highly recommend taking a trip on the bus.
