Fair Oaks Dog Park spreads across a sprawling fenced area with distinct zones that let you actually separate your dog by size rather than cramming everyone into one pen. The main field opens up with good sightlines—you can watch your dog roam without losing them in a crowd, which matters on weekends when Sunnyvale dog owners show up in force.

Dogs roam on a mix of grass and decomposed granite, so paws stay relatively clean even after rain. There’s a dedicated small-dog section if your dog weighs under 25 pounds or so, which keeps the ankle-biters from getting trampled by the 80-pound retrievers that tend to dominate the main area. Water bowls are available, though you’ll want to bring your own water on hot days—the park gets full sun in the afternoon, and shade is limited. The park itself runs from dawn to dusk, and mornings before 10 a.m. tend to be quieter if your dog prefers calmer company.

The park sits on North Wolfe Road near the Sunnyvale Community Center, making it easy to find if you’re already in that part of town. The parking lot is right there, so you’re not hauling your dog far from the car. Fair Oaks fills up noticeably on weekend afternoons, so if you want elbow room and fewer dogs, aim for weekday mornings or early evening after the 5 p.m. rush. The decomposed granite surface drains reasonably well but does compact into hard patches in heavy-traffic zones—your dog might appreciate the small-dog area’s slightly softer footing if they’re older or have joint concerns. Leashes are required to enter and exit the park, so have a grip on yours before the gate opens.
