Del Oro Park in Petaluma spans nine acres and is the largest dog park in the area, making it worth the drive if you’re in Sonoma County Wine Country and want serious space for your dog to run. The park has designated off-leash areas where dogs under voice control can roam freely during set hours, so you’ll want to check those times before heading over. There are separate dog run areas throughout the park, which helps manage the flow of dogs and gives you options depending on your dog’s energy level and play style.

Beyond the off-leash zones, Del Oro Park has walking trails winding through the grounds where you can keep your dog on-leash and enjoy the scenery at a slower pace. The landscaping is genuinely nice—lush green spaces and shade in several spots, which matters on warmer days. You’ll see other dog owners out regularly, so it’s a social spot if your dog enjoys meeting others. The park’s relatively flat terrain makes it accessible even if your dog has mobility concerns or you’re not up for a challenging hike.

The off-leash policy does require your dog to be licensed, so make sure you have that sorted before visiting. The park enforces voice control rules, which means your dog needs solid recall—if your dog doesn’t come reliably when called, the leashed trails are a better option. There’s generally good parking near the entrance, and the park is easy to find in Petaluma itself. If you’re spending a few days in Wine Country and your dog needs a real workout, this is a solid choice for letting them burn energy while you get some exercise too.
