In the begining of World of Warcraft, there is no better place than your starting zone, it is no point that in going anywhere else, wow power leveling will be super quick and the 10 -15 first levels shouldn’t take more than a couple of hours. The Quests are also very linear and self-explanatory.
Horde:
Goblin – Kezan / Lost Isles until level 12
Orc and Trolls – Durotar until level 10.
Blood Elves – Eversong Wood until level 10
Tauren – Mulgore until level 10
Undead – Trisfal Glades until level 10
Pandaren – Wandering Isle until level 10
Alliance:
Worgen – Gilneas City / Gilneas until level 12
Draenei – Azuremyst Isle until level 10
Dwarves and Gnomes – Dun Morogh until level 10
Humans – Elwynn Forest until level 10
Night Elves – Teldrassil until level 10
Undead – Trisfal Glades until level 10
Pandaren – Wandering Isle until level 10
Level 10 – 20
After finishing your starting zone, choices will start to open up and you get to travel a bit. But if you want to level as fast as possible I would advise you to go to a zone near your starting zone. Time spent traveling is time wasted, and because leveling will still be extremely fast there is really no point in going too far.
Westfall Level 10 – 15
Westfall is a good zone for humans to go to after Elwynn forest. The instance the Deadmines (15 -20) is also in this zone, so if you can get a group together it’s a good run to get some starting gear and fast XP.
Azshara Level 10 – 20
Mostly a horde zone, Azshara is good for leveling as it’s close to Orgrimmar and can be combined with leveling in the Barrens and Ashenvale.
Bloodmyst Isle Level 10 -20
Bloodmyst Isle is the next zone up for Draenei who are finishing up their starting zone.
Darkshore Level 10 -20
Darkshore is a good place for Horde characters to level in their 20’s. There are a lot of quests here and it connects with Ashvale where you can go when you finish up.
Ghostlands Level 10 -20
Ghostlands is the place to go if you are a Blood Elf that’s finished in Eversong Woods, as the two zones are connected.
Loch Modan Level 10 – 20
Dwarves and Gnomes can move on to Loch Modan after finishing up in Dun Morogh.
Northern Barrens Level 10 – 20
One of the most famous zones in WoW, for both its legendary chat channel and for being a good leveling zone. Most Orcs, Trolls and Tauren will find their way here after their starting zone. All other horde characters should consider traveling to Orgrimmar and then to the Barrens to level. Loads of quick quests here, and the Wailing Caverns instance.
Silverpine Forest Level 10 – 20
Undead characters can start doing quests here after finishing up their starting area. Shadowfang Keep is also located in this zone.
Ruins of Gilneas Level 14 – 16
This zone is connected to both the Worgen Starting Area and Silverpine Forest.
Redridge Mountains Level 15 – 20
This zone is located next to Elwynn Forest, and is ideal to move on to after / when leveling in Westfall.
Instances :
I start using the Dungeon Finder as soon as I can. Just combine using the Dungeon Finder for groups while doing quests elsewhere. You get fast XP and good gear in turn making leveling faster. In the early levels most players are decked out in Heirloom gear, and you will blast through instances in no time.
Ragefire Chasm Level 15 – 21
Deadmines Level 15 – 21
Wailing Caverns Level 15 – 25
Shadowfang Keep Level 16 – 26
Level 20 -40
Now that you are level 20, a few more choices will open up for you. Some of the previous zones will take you into one of the ones below, and cutting down traveling time is still important to level fast. Some zones like Ashenvale and especially Stranglethorn is worth traveling to as the leveling here is very quick.
Ashenvale Level 20 – 25
Ashenvale is a very good leveling zone for both factions with tons of quests and some good rewards. The instance Blackfathom Deeps is also located here with some good quests and will provide quick XP if you do a run or two.
Duskwood Level 20 -25
Duskwood is primarily a Alliance zone and provides some good leveling. It’s a good place to go after Redridge Mountains as it lies right next to it and some quests cross over.
Hillsbrad Foothills Level 20 – 25
Primarily a horde zone after the cataclysm. Hillsbrad provides horde characters in their 20’s with a lot of quests.
Wetlands Level 20 -25
Mostly a Alliance zone, some decent XP here.
Arathi Highlands Level 25 – 30
Arathi Highlands is an excellent leveling zone for both sides. And if you like PvP you can get some quests here for the Arathi Basin battleground so you can PvP while you level for a while.
Northern Stranglethorn Level 25 – 30
Northern Stranglethorn is a legendary zone, the quest XP here is great and leveling is fast. There are usually a lot of people here, and you will probably be killed a few times if you are on a PvP server.

Good place to move on to from Ashenvale or the Barrens. Quick XP and quite a few quests.

After finishing up in Western Plaguelands you can move on to the Eastern Plaguelands. Some of the quests will send you there anyway.
