Goron Mines, I think. To shoot those bulblins with bow and arrow was funn xD

City in the Sky is my fave!

Snow ruins all the way!

Arbiter's Grounds

I would have to go with the Goron Mines. They just felt so much like an mine that would be made by rock men that eat rocks.

My favorite dungeons were "Lakebed Temple" and "Arbiter's Grounds", both tied.

PS: I love water dungeons, as odd as it may be.

Temple of Time for nostalgia and City in the Sky for the most fun (Argorok fight!).

Temple of Time. It was awesome to hear the same music from OoT.

i loved hyrule castle!had quite a cool music too

I didn't enjoy Palace of Twilight, but besides that, I loved all of the dungeons. The dungeons are what really make TP the best Zelda game. They're the most labyrinthine, beautiful, FUN dungeons in any Zelda game. But if I had to choose, I'd say City in the Sky. I loved clawshotting around.
