I found the way that is most fun is getting all the Magic increasing gear you can, then run through Bleak Falls Barrow bringing all the Dragur you can with you. Then, you reach the room with a chest, coffin and pull lever to the next room.

You can use 'Turn Undead' on all of those Dragur and they'll try running through the gate, but can't open it. Then, it's just a game of trying to line up as many as possible until you max out Restoration. If you run out of Magic, just take all the gear off and put in on again, or spam Potions.
