I'm sure most of us know of Blackreach, as it's the location of an elder scroll, and one of the various places you get sent to for the main storyline.
If you don't know where it is, it's underneath the ruins of Alftand, Mzinchaleft, and Raldbthar.
Anyway, all i'm getting at, is, if you're lower leveled, you'll probably run through to where you need to go for the quest, but, if you're high enough, i definitely suggest exploring the entire dungeon, there's a ton of valuable loot and the gold on your enemies there will stack up nicely.
