Dodongo's Cavern

Dodongo's Cavern is the second of three dungeons that young Link in Ocarina of Time must visit in order to acquire the three Spiritual Stones. The Gorons use the cavern to get the rocks they eat. When Darunia refused Ganondorf the Spiritual Stone, Ganondorf infested the cavern with Dodongos and sealed the entrance. To clear out this infestation, Link must defeat King Dodongo, the boss of the dungeon. As a side note, Dodongo's Cavern is what appears on the maps in the N64 games when you first acquire the map from its chest.
