One embodiment of the invention provides a method to allow a user to navigate through a virtual environment using breakpoints. Each breakpoint may store a context of a virtual location within the virtual world, recorded for the moment in time when the breakpoint was created. Further, in a persistent virtual world, the user's avatar may be restored to a given breakpoint location, as well as restoring elements of the virtual world, based on what was present within the virtual world when the breakpoint was created.
