UPDATE: Progress gallops forward and mount requirements have changed ... Visit our updated WoW Rookie mounts post for the latest mount information.
Hitting level 30 is a major milestone in today's World of Warcraft: the level at which you get your mount. Up to this point, you've spent plenty of time hoofing it, getting to know the lay of the land. On the back of your trusty steed, you'll be able to zip across increasingly larger zones and quest areas in style. You'll start off on a standard ground mount, such as a Horse, Wolf or Kodo. Later, you can upgrade to faster versions of those creatures and eventually to mounts that can fly (in Burning Crusade and Wrath content).
Mounts used to become available at level 40. Now that the game extends to level 80 and early character progression has been sped up, you get to speed up at an earlier level, too.
