This historic park, located in Los Angeles County where the Simi Hills meet the Santa Susana Mountains, sits in the western part of the Transverse Ranges and is rich in natural, historical, and cultural significance. The landscape is dominated by high, narrow ridges and deep canyons covered with abundant plant life—chaparral scrub, oak woodlands, and seasonal wildflowers that change the hillsides throughout the year. From various points along the trails, you get panoramic views of the rugged terrain that stand in sharp contrast to the developed communities visible below.

The park works well for day hikes of varying difficulty. Depending on which trails you take, you might encounter Native American historical sites or remnants of the area’s ranching past. The elevation gain on some routes can be steep, so it’s worth knowing your dog’s fitness level before starting out. Water sources aren’t always reliable on the trails, so bring enough for both of you.

Getting there is straightforward. Take the 118 Freeway to the Topanga Canyon Boulevard exit, then head south on Topanga for about a mile. Turn right on Devonshire and continue for half a mile until you reach Chatsworth Park South, a Los Angeles City Community Park where you’ll find free parking. The hills surrounding this community park are the actual parklands for Santa Susana Pass State Park, so you’re essentially accessing the larger park through this entry point.

It’s a day-use area, so plan to head out in the morning and finish before sunset. The terrain can be rocky and exposed in places, and it gets hot in summer, so spring and fall are more comfortable for longer hikes. Bring a hat and sunscreen for yourself, and watch for snake activity during warmer months, especially on less-traveled stretches.
