Answer: Walking. Nothing else ... just boring, tedious walking through either empty, or wiped out zones ... Who would want that? :-/ And why?
That’s where a wonderful thing called “a design” comes in. Put some thought into where you put your fast travel point and how you design areas and you don’t have such an issue.
This is something about Morrowind I really came to appreciate, especially the way they made the most out the space given by forcing you to travel in curved lines.
