The district has an inventory of 5,600 acres of public owned land, including hundreds of acres of land in the Simi Hills.
The purpose of these areas are to preserve the native landscape, as well as function as a wildlife corridor that protects the natural habitat for wildlife and flora.

Simi Peak (the highest peak in Simi Valley) is accessible from this trail system via China Flats in the Chesebro trail system.
