The
Emirates Air Line cable car system crosses the River Thames between Greenwich Peninsula, to the south, and the Royal Docks, to the north. Cabins arrive every 30 seconds, or so, and flights take about 10 minutes each way. As well as being part of London's integrated transport system run by Transport for London (
TfL) it is a great tourist attraction.
The Emirates Air Line cable car system can be seen from all around the area.
