Gerudo Desert
This is a location in Ocarina of Time. It is in the northwest corner on the map and is home to the Gerudo and the Spirit Temple.
This is also a location in Twilight Princess in the Desert Province. It is located in the southwest corner of the Twilight Princess map. The dungeon Arbiter's Grounds is located in it as well as the first shard of the Mirror of Twilight.
It expands on a vast territory, but most of its surface is a barren wasteland with no signs of life other than some monsters. Aside from the Arbiter's Grounds, the Gerudo Mesa is the only other important location there. It is where the Cave of Ordeals, a large optional dungeon, is found.
Strangely, the Gerudo Desert is completely cut off from the rest of Hyrule. It can first only be reached by being shot out of Fyer's cannon, and can only be left by warping.
