[2] The wilderness is located about 12 miles (19 km) northwest of Ojai[3] in the Santa Ynez Mountains and spans most of the watershed of Matilija Creek, the main tributary of the Ventura River.[5] The area is extremely remote and rugged and is characterized by rock outcrops, crumbling slopes and steep canyons filled with brushy vegetation, with some gentler terrain in the northern part of the wilderness.[8] Wildlife found in this area include black bear, deer, mountain lions, bobcats, coyotes, foxes, quail, rabbits, raccoons and squirrels.[11] The Upper North Fork of Matilija Creek, today a recreational trail, was historically a mail route between inland and coastal parts of Ventura County before the construction of Highway 33 bypassed this area.[18] A coalition of environmental groups and hikers reached a settlement in 2016 for a public easement through the Bonsall ranch, in return for relocating part of the trail east of Matilija Creek and putting up signs to discourage trespassing off-trail.
