The Desert Sector is a main surface sector of Lyoko. It is also the one with the most dangerous monster attacks. Most of the creatures can get around easily here. The Desert is made out of a collection of dry, rocky plateaus. There is very little greenery, the only trees being scattered here and there. Here, X.A.N.A. can create sandstorms, break apart the plateaus, and even tilt them at 90° angles to immobilize the Lyoko Warriors. The Desert is made up of two levels: the lower and higher levels. The higher level's plateaus are very large, and most towers in the sector can be found here. Large creatures, such as Megatanks, Bloks, and Krabs inhabit this area. The lower level's plateaus are very small, and small sharp rocks are littered.
In The Pretender, X.A.N.A. possessed Aelita and used her to completely destroy the Desert. However, Jeremie and Aelita manage to recreate the Desert Sector in Double Take as it was the first surface sector to make a reappearance.

Most of the Desert Sector is large flat platforms of sandstone. There are sharp thin rocks in it as well. Some act as connectors between the platforms. The landscape is lined with Lyoko Wires and towers.
The Desert Sector contains an oasis complete with palm trees and small puddles of water. It contains minor shrubs. It appears to have water, but this is only a surface layer. It actually covers a long drop to another plateau. It appeared in Seeing Is Believing.
The Desert Sector contains occasional craters. One such crater contained the tower used to run William Clone. Another leads to a tunnel and then another tower.
The formations of the sector have various tunnels connecting them. Some of these are barely wide enough for a Megatank.
Some sections of the Desert Sector contain rock spikes.
