The Desert Sector is a 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 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, Blocks, 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 reapearance. Fans have given it the name Sector 2. This is mainly because it is opposite of the Mountain Sector, which fans have dubbed Sector 4.

Trivia

In Seeing is Believing, it is discovered that there are surface layers in the Desert.

The Desert contains the Tower which Jeremie activated to create and support the clone of William; this has been shown in Double Take and Wreck Room.
Every time the Skidbladnir leaves Sector 5, it exits in the Desert Sector.
The Desert Sector was one of the sectors to survive between seasons 4 and 5, although it appears to be colored more green.
