My story is a questing story, and as such, you guessed it...traveling. I actually spend a lot of time of traveling sections, not because I write copious details about what that tree looks like (although it is a pretty tree), but because I only skip ahead if I am switching to one of my other POV characters that are not with that traveling group of adventurers. I might skip a few days here and there, but I think its important to at least give the reader a "picture" of what those days looked like. If you don't, the reader doesn't know what happened during those days. What that does (IMO) is it pulls the reader out of that story of the MC/POV character.
Also, have you ever gone on a road trip with someone? Its such a great way to get to know one another a develop a relationship. This is great for character relationship development. Also, as others have pointed out, throw some road blocks in along the way. That can help drive the plot. I think it is important to give the reader enough details so that they know what the land the characters are traveling through looks like, but not so many details that the story becomes about the land. It needs to stay on your characters. Just give a few chapters of LOTR a read and you will see, that while we love LOTR, the writing for this day and age is kind of...boring. I say that with extreme caution because I love LOTR. LOVE it. But that's because of the escapism appeal and depth of the world, not because I found the writing to be extremely engaging.
Anyways, that's my 2 cents.
