It might be my admittedly limited genre of reading, but the first long earth book does this for me. Most of the adventure is just stepping through hundred of varying types of earth, most unpopulated, and exploring to see what is out there.
There's more to the book than that, but those are my favorite sections.
It's written by Pratchett and Baxter and although not without its faults, the first one is still a fun read for me.
