Ask a Mill Valley dog owner where they spend their mornings, and you will hear about the bay shoreline at Bayfront Park or the fire roads above Blithedale Canyon. Few towns in the Bay Area give dogs this much room to roam within minutes of home. As a team that helps buyers settle across Marin County, we hear how often outdoor access shapes a home search. Here are the dog parks in Mill Valley and nearby open spaces that local owners return to again and again.
Key Takeaways
- Bayfront Park offers Mill Valley’s main off-leash dog area
- County preserves allow off-leash dogs on fire roads under voice control
- State parks and Muir Woods have stricter rules for dogs
- Dog-friendly cafes round out a morning outing
Bayfront Park Dog Area
Bayfront Park, at 450 Sycamore Avenue, is the go-to off-leash spot for dog owners in Mill Valley. The dog area is a large, open grassy space with Richardson Bay along its edges and the Mill Valley-Sausalito Path running beside it.
Benches and picnic tables give owners a place to settle in while dogs play. It is a natural first stop for new residents looking to meet other dog owners in town.

Camino Alto Preserve
For dogs who love a climb, Camino Alto Preserve covers about 170 acres on the ridge between Mill Valley and Corte Madera. The main trailhead sits where Overhill Road meets Escalon Drive, with street parking nearby.
Marin County Parks allows dogs off-leash on fire roads here, as long as they stay under voice control and owners carry a leash. On signed trails, dogs need to stay on a leash no longer than six feet. Some areas close at night from February to July, so watch for posted signs.

Blithedale Summit Preserve
At 639 acres, Blithedale Summit is the largest preserve along Mount Tam’s north ridge. It links Mill Valley, Larkspur, and Corte Madera, and it is a top choice for owners of high-energy dogs.
The Old Railroad Grade starts from a gate on West Blithedale Avenue just past Lee Street. It follows the route of the 1890s Mill Valley and Mount Tamalpais Scenic Railway and makes for a steady, gradual climb.
