This paper identifies several problems with navigating and visualizing guided tours in traditional hypermedia systems. We discuss solutions to these problems, including the representation of guided tours as 3D metro maps with content preview. Issues regarding navigation and disorientation are addressed and we suggest a combination of the metro map and an intuitive navigation system. Finally we present a prototype (Webvise3D) which implements our ideas.
