Dalaran was the main hub for "Wrath of the Lich King "(WotLK) expansion of "World of Warcraft" (WoW). "Cataclysm" has now struck Azeroth and the portals in and out of Dalaran are no longer existent. Characters still need to go through the WotLK quests once they hit Level 68 or higher, and Level 80 and over characters may still return to Dalaran for achievements and training. Your easiest path to Dalaran depends on the level of your character.
