I like Zangermarsh mosly because of the nifty looking mushrooms.
I know people will hate me for this, but Vashj'ir, Shimmering Expanse in particular, has very much grown on me for its surreal imagery and the fact that I've been staring at the place for a while to hunt Poseuidus. I've sort of had to absorb the scenery, and I noticed it's good stuff.

Un'Goro Crater would be my favorite. I like the abundance of green, the dinosaurs, the devilsaurs, and pre-cata, climbing around the cliffs.
My favorite zone is Twilight Highlands. Maybe because I like dragons so much. :)
You're making me choose? Ouch...I really love most of the zones in WoW, but uh, I think I like "Deadwind Pass" a lot, more because of how the mood of the whole zone just makes you feel like you're in a classic horror movie, really, take a look at the stone bridge, the long drop and grey colours adds to all the mysteriousness there is in the zone, oh and let's not forget the Karazhan crypts...not that I've ever been there.../cough
My all time favorite Zone is Nagrand, It stands in stark relief of the shattered remains of draenor, an untouched (nearly anyway) paradise of unparraleled beauty and peace. The music itself invokes reverance for the orc's ancestral home.
I really enjoyed the Lost Isles in the goblin starting area. For a low-powered character, you really get a sense of accomplishment, and the quests showed right away that Cataclysm was going to be all different. It's a shame we can't go back!
My fav area has got to be Uldum, because you get to meet Indiannn... i mean Harrison Jones.
My favorite zone has to be Dun Morogh. I love all the snow everywhere and all the funny dwarfs & gnomes. It's also home to my favorite, well, home, Ironforge.
I am a huge fan of the *new* Feralas. Every part of it is so beautiful; from the ancient ruins, to the lush green forest. It really is a well-made zone! Very comforting.
My favorite zone, the zone that I always get excited about with a new character has to be...Westfall, actually. Yup. Westfall.It probably has something to do with the fact that that was where I had quite a few firsts. I saw my first major storyline come to completion on my first character (The Defias storyline), I did my first dungeon (The Deadmines), I healed for the first time, etc.Plus, you can never forget the ever-lovable Westfall Chicken.
My favourite zone is the twilight highlands. I love the little houses of the wildhammer dwarfs. It reminds me of the Shire in a way. Too bad the Twilight Hammer had to devastate this beautiful land.
I would say Uldum is my favorite zone, the Harrison Jones quests are cool and the Lost City looks amazing, all thats left is for some future patch to make the Lost City a more populated player hub the same way Dalaran and the home cities are.
My favorite zone is probably Nagrand. I remember flying around mining, trying to make the perfect path to get all the mines. PVP was big there as well back in the day and you can't forget the ring of blood! To top it off, the scenery was beautiful and great to look at.
