There’s a few Whiting Ranch hiking options, but Red Rock Canyon is the most popular for a good reason. The gently climbing trail makes it way up a oak woodland canyon, eventually ending in a smooth red rock canyon like you’d see in Arizona (but unique to Orange County). Whiting Ranch Wilderness Park is rich with wildlife. I often see squirrels and lizards, and less often deer. The hike is mellow, easy, and is great for families.
