The Forest of Menos (メノスの森, Menosu no Mori) is an area below the surface of Hueco Mundo's desert where the average Hollow hide from the Arrancar.

The forest is filled with large trees made of a silvery quartz substance. These trees extend to the surface and dot the landscape of the desert in Hueco Mundo. Arrancar have a considerable amount of influence here, judging by a large group of Hollow bowing down upon seeing an Arrancar. Countless Gillian class Hollow live here and follow the commands of the Guardian of the Forest of Menos and his followers. The Adjuchas in charge of the Forest of Menos are under the command of a few select Vasto Lordes.
