It is called Cave of Ordeals.
In OoT my favorite temple is the Forest temple, because of the eerie music.
In MM I like the Stone Tower Temple the most, just the idea of playing a dungeon upside dungeon is awesome.
In WW my favorite temple is the tower of the gods. I also like the temple of Time in TP.
I like the Snowpeak ruins in TP, because I like house dungeons and the temple is easily breakable.
My favorite temple in Skyward Sword is the fire sanctuary, but that is probably because I visited the temple much to hunt bokblins for their skulls. I also like that you can enter the dungeon through the bird statue.
