In Brea, you can walk among some of Southern California’s only native Coastal Redwoods at Carbon Canyon Regional Park. The Redwood Grove Hike covers about 3 acres of surprisingly lush terrain, with towering trees that block out most of the sky and create a cool, quiet space that feels nothing like typical Orange County. The trails are well-maintained and gentle—nothing steep or technical—so it works for dogs of varying fitness levels and ages.

Dogs are welcome on leash throughout the park. The scent work alone keeps most dogs engaged for the entire hike; the forest floor is rich with smells from wildlife, moisture, and decomposing vegetation that you won’t find on the chaparral trails elsewhere in the region. The canopy is dense enough that even on warm days, it stays relatively cool under the redwoods, which is a genuine advantage if you’re visiting during Orange County’s hotter months.

Beyond the redwood grove itself, Carbon Canyon Regional Park has open meadow areas where you can let your dog stretch out after the hike. The park is also known for its creek, which runs through the property and offers water access if your dog wants to cool off—useful on those warmer days. Wildlife in the area includes squirrels, birds, and occasionally deer, so keeping your dog on a leash is both a safety measure and respectful to other visitors who come here specifically for the quiet, natural experience.

Parking is straightforward, and the trails connect to other paths in the park if you want to extend your visit beyond just the redwood section. Bring water for both of you; there aren’t facilities or shade structures in the grove itself, just the natural canopy. The park’s website has trail maps and current conditions, which is helpful before you go since seasonal factors can affect trail quality.
