After three years of weekend hikes with Arie, I have very strong opinions about which trails are actually dog-friendly and which just technically allow dogs. These are the ones where I felt safe, where Arie came home truly tired (not just bored-tired), and where I'd happily drive back next weekend. All within about 90 minutes of Orange County, all tested by us more than once. A few of my LA picks are at the bottom — worth the gas.
