London Cable Car

Opened in 2012, this cable car crosses the Thames between the O2 Arena on Greenwich Peninsula and the Royal Docks, its gondolas climbing to around 90 meters for views over the river, Canary Wharf's skyscrapers, and the Thames Barrier downstream. It functions as a genuine part of London's public transport network as much as a tourist attraction, making it one of the more unusual ways to cross the river without walking or taking a boat. Its relatively modest must-see and culture scores in this batch reflect that it's a niche experience rather than an essential London sight, appealing mostly to visitors interested in unusual viewpoints or already in the area for the O2 or ExCeL. The ride itself is brief, so it suits a short detour rather than a dedicated outing.
