London's legendary Tube network remains the quickest and easiest way to get around the city, though it is best avoided during rush hour. The famous red buses are a more pleasant, if slower, way to get around. The ubiquitous black cabs are excellent but Uber and other taxi apps are also popular.
London's main attractions are fairly close to one another; if the weather is nice, walking or taking a riverboat are good options. Driving is not a good option in central London, as parking is difficult to find and very expensive. A 'congestion charge' is also payable by those driving into central London from Monday to Friday 7am-6pm.
