Dungeon Exploration

[Grand_Unified]

Since I'm directionally challenged and an altaholic I never delved into several of the high level dungeons back in the day on live. Now that I've worked my way up on this server, I would like to familiarize myself with the dungeons I know little about. However, as a tank/puller I would really like to know my way around and what I can safely pull before I start jumping into groups there. So my question is: Does anyone know of an easy way of exploring by myself? I've thought about creating a toon on a server with some of the later expansions, since I've heard with the current gear and higher levels you can bulldoze through the old world zones, but any other suggestions would be appreciated!
