Location of Ilex Forest in Johto.

Ilex Forest (Japanese: ウバメのもり Ubame Forest) is a dense forest located in southern Johto, directly west of Azalea Town. The forest's trees are so close together that all light is blocked out, and the forest seems to be in a perpetual night.

The only important feature in the forest is a shrine to Celebi.

In Pokémon Crystal, if a player managed to obtain the GS Ball, either through the Pokémon Mobile System or use of a GameShark, and if Kurt had examined it already, placing the GS Ball in the shrine would bring a level 30 Celebi to face the player.
