self explanatory, my fav dungeons are goron mines(TP)cuz its loads a fun,arbiter's grounds(TP)epic final boss and epic item(spinner ftw,even tho its almost useless) and stone tower(MM)for being epicly hard

In Twilight Princess, my favourite dungeon is the Temple of Time, so confusing first time through.
In Ocarina of Time it would be the Spirit Temple, so difficult when I was a kid.
In The Wind Waker it would be the Earth Temple, so easy, but one part was impossible.
In Spirit Tracks it would be the Sand Temple, it was so confusing, and the boss was impossible.
In Majora's Mask it would be Stone Tower, it was one of the most difficult dungeons in a Zelda game.
Those are my top five Zelda games too.

OoT: Spirit Temple
WW: Wind Temple
TP: City in the Sky

The Water temple from OoT and The Stone Tower from MM.
What?I love a good challenge...

WW:Gannon's Castle TP:Hyrule Castle

My favorite would be the Shadow Temple from OoT. It was epic and fun, plus you get Hover Boots. w00t.

OoT: Spirit Temple and Shadow Temple
ST: Spirit Temple
Majora's Mask: Stone Tower Temple

MM: Stone Tower <3
OoT: Shadow Temple (the only actual temple or area that was scary as shit with a scary as shit boss. Excluding TLoZ Minish Cap)
ST: Spirit temple, just cuz musik.
