This cable car makes quick work of the journey from the Greenwich Peninsula to the Royal Docks. Although it's mostly patronised by tourists for the views over the river – and the views are good – it's also a listed part of the transport network, meaning you can pay with your Oyster Card and nab a discount while you're at it.
Capable of ferrying 2400 people per hour across the Thames in either direction. Sometimes closed in high wind.
