California offers some of the most breathtaking and dog-friendly hiking destinations in the country, making it a paradise for outdoor-loving pups and their humans. In the north, trails in Redwood National and State Parks near Trinidad invite you to wander beneath ancient redwoods with your leashed dog, while Manzanita Lake at Lassen Volcanic National Park offers an easy, scenic loop with views of Mount Lassen. Down south, Runyon Canyon in Los Angeles is a social hotspot with off-leash areas and sweeping views of the city. Nearby, Griffith Park delivers quieter trails that climb toward the iconic Griffith Observatory. Wherever you roam, come prepared: keep your dog leashed unless signage says otherwise, pack water and snacks for both of you, and always carry waste bags. With a little planning and a good trail beneath your feet, you and your dog can explore the best of California’s natural beauty—together.
