Encompassing 4,800 acres in the Santa Susana Mountains between Chatsworth and Simi Valley, this extraordinary Rim of the Valley Trail Corridor parkland stretches from the 118 freeway five miles northward to Las Llajas Canyon, and forms the most critical wildlife habitat linkage between the Simi Hills and the Santa Susana Mountains. Spectacular sandstone boulders, outcroppings, oak savannahs, and perennial water sources provide diverse habitat for birds, mammals, and reptiles.

Several easy to moderate trails traverse the park and provide exhilarating views of the Simi Valley and Santa Susana Pass.
