Underground

The London Underground is one of the easier subway systems to use. There are very clear maps of the system posted, using color coded lines, which give clear indications of all stations and where you can hop over to another line. These lines have names such as the "Waterloo", the "Jubilee", and the "Piccadilly" Lines.  It is recommended that tourists purchase one of the "London Travel Cards"
