There are many ways to get from A to B in London, with tubes, buses and Boris bikes among the most popular and convenient forms of locomotion.
However, if you want to turn your time travelling into an opportunity to do some sightseeing then you may be interested in taking a ride on some of the city's quirkier public transport options.
The Emirate Air Line certainly falls into this category, and is a cable car which runs between the Greenwich Peninsula and the Royal Docks, offering travellers the opportunity to enjoy some truly amazing views of the capital from up above.
The trip itself takes around ten minutes, with the cable car passing over the iconic O2 Arena on the banks of the Thames. Not only is this a quick and convenient way of getting from one side of the river to the other, but it is also much more enjoyable than making the crossing underground.
Views from the cable car are simply breathtaking, and Oyster Card holders can take a spin on the Emirates Air Line for as little as £3.20 per adult or £1.60 for children, while a batch of ten journeys costs as little as £16.
Another great way to cross the Thames without having to head beneath the ground is by river bus, and these can be boarded at a number of locations along the banks of the river.
As with the Emirates Air Line, river buses are accessible using Oyster Cards and offer sightseeing opportunities as well as being a convenient form of public transport.
You'll find stops at places like London Bridge, Tower Pier, and the O2 Arena in Greenwich, while a special Tate to Tate route also exists, with river buses running between the Tate Modern at Bankside Pier and the Tate Britain at Millbank Pier.
