William S. Hart Regional Park in Newhall sprawls across 265 acres of rolling hills and scrubland that feel surprisingly remote despite being part of Los Angeles County. The park’s centerpiece is Hart’s former home, a mansion that’s now a museum dedicated to the silent film era and the life of William S. Hart, the cowboy star who built this retreat in the 1920s. Walking the grounds gives you a real sense of old Hollywood history mixed with genuine outdoor space.

The hiking trails here are what make it worth the drive north from the city. They wind through the rugged landscape with decent elevation changes, so you’ll get some actual exercise rather than just a casual walk. The views of the surrounding hills are worth the effort, especially on clearer days when you can see across the Santa Clarita area. Dogs are allowed on the designated paths, which means your dog can work off some real energy while you’re exploring.

Beyond the trails, there are picnic areas scattered throughout if you want to bring lunch and sit for a while. The park maintains a small Western-themed village area with some historic buildings that add to the atmosphere without feeling overdone. It’s the kind of place where you can spend a few hours hiking, grab some shade under oak trees for a snack, and see the museum if you’re interested in the historical side.

Parking is straightforward and relatively easy to find. The park can get busy on weekends, especially during cooler months, but the acreage means it never feels completely crowded. Bring plenty of water for both of you—the trails have minimal shade in spots and the sun exposure is real up there. The elevation gain is moderate enough that most dogs handle it fine, but older dogs or those not used to hiking might find it challenging.
