whats your favorite dungeon in the zelda series?

Mine would have to be the Temple of Time, followed closely by either the Palace of Twilight or the Arbiter's Grounds. All of which have you trying out terrific new items (with the exception of the PoT, which gets points simply for the environment/art design), and facing off against some of the series' coolest bosses.

A couple of other dungeons that I really love are OoT's Shadow and Spirit Temples.

Explorer's Crypt from OoS. Awesome music and an epic boss fight as well.

Level 4, 2nd Quest in LoZ. Lots of tough enemies, tough to navigate with the secret passages and walking through walls.

The first time you visit Hyrule Castle in LttP, 'cause it's easy.

You like dungeons that are easy? And you call yourself a Zelda fan. How scandalous.

Goron Temple in TP... walking on the ceiling was different. Very good idea.
Also Forest Temple for OOT.. only because I looove the corkscrew hallway.

Eagle Tower in Link's Awakening

non-linear, clever puzzles, epic feeling, simply the best 2D dungeon in the series

I always had a soft spot for the Spirit temple in OoT, I liked going through it both as a child and an adult.

And i love Stone Tower Temple for its complexity and its music :3

OOT- Forest and spirit temple (definitley not water, even though it's not that bad after you memorise it).
