More open space than park, the Preserve is part of a patchwork of large habitats that make up north county San Diego. Wildlife currently moves between tracts of land such as the Cleveland National Forest, Palomar Mountain, BLM land and the Rancho Guejito, a privately owned ranch that spans 23,000 acres east of Escondido. Hellhole Canyon is a centerpiece connecting them all.
