The Cave of Ordeals is a long and arduous mini-level, located in the South-Eastern corner of the Gerudo Desert, below the centre piece of the Eldin Bridge.
Within the cave, Link has to fight his way through hordes of enemies, some of which may not yet be known to him.
At the end of the cave, there is a fountain in which the Great Fairy resides.
