The Red Rock Road Trail in Topanga is all about the geology—sculptured sandstone formations that look like nature’s own architecture, with arches and caves carved right into the rock face. The first half of the hike winds through these formations, so you’re constantly navigating around and under interesting stone shapes. Your dog will probably find this section the most engaging, with plenty of varied terrain to keep things interesting.

Once you get past the initial rock formations, the trail starts climbing toward the ridgeline to the west. The ascent is gradual enough that most dogs handle it fine, and there’s a bench about halfway up with a solid westward view—a good spot to let your dog catch their breath and you can actually enjoy the scenery instead of just hiking past it.

Getting there takes some navigation through the Topanga Canyon area. From the 101, take Valley Circle Boulevard south toward the mountains. After about 0.6 miles, turn right onto Valmar Road, then continue to Mulholland Highway. The real turn is onto Old Topanga Canyon Road, which you’ll follow for roughly 3.9 miles as it climbs over the ridgeline and down into the canyon. Once you hit Red Rock Road, follow it through the residential neighborhood until you reach the unpaved portion that leads to the actual trailhead.

The trail itself is moderately challenging but manageable for most dogs in decent shape. What makes it worth the drive is that you’re not shoulder-to-shoulder with other hikers the way you are at more famous Topanga spots. The sandstone formations make for good photo opportunities if your dog cooperates, and the ridgeline views at the top give you a real sense of accomplishment. Bring water—there’s no reliable source on the trail itself, and the exposed sections can get hot in afternoon sun.
