I tend to chill out in Duskwood, Zangarmarsh, and Howling Fjord quite a bit whenever I'm leveling a new character or just trying to pass the time before a raid. I'm not sure if those zones are really the "most beautiful," but something about them certainly resonates with me.
There's something oddly pretty about Hellfire Peninsula, too. :)
