Miwok Trail is the only dog-friendly trail in Tennessee Valley, and it’s a solid choice if you want something with real elevation and views in Mill Valley. The hike climbs just off the ridgeline through rocky, dirt terrain—don’t expect shade or lush greenery, but do expect your dog to work for it.

The tricky part is navigation. Stay right on Miwok Trail itself. Two unmarked fire roads branch off straight ahead and lead nowhere useful—they end at a gate and an FAA antenna, so ignore them. It’s easy to accidentally head that direction if you’re not paying attention. Once you commit to the right fork, Miwok Trail angles across the upper reaches of Tennessee Valley, and that’s when the views open up. You get genuine panoramic sightlines across the surrounding landscape, which makes the climb worth the effort.

The terrain is unforgiving—rocky and exposed—so bring water for both of you. Your dog will need good footing and shouldn’t have tender paw pads. The lack of vegetation means minimal shade, so timing matters if you’re going in summer. Early morning is smarter.

What makes this hike special is how few dog-friendly options actually exist in Tennessee Valley, so Miwok Trail fills a real gap. If you’re staying in Mill Valley and want to get elevation and expansive views without driving to a more famous peak, this works. The challenge level appeals to dogs and owners who aren’t just looking for a casual stroll.

The Bay Area Hiker website has detailed trail maps and descriptions if you want to study the route before heading out, which is honestly worth doing given the unmarked roads that can pull you off course.
