Foster City Dog Park sits right at the intersection of Foster City Boulevard and Bounty Drive within the scenic Boat Park area, and it’s a genuinely solid spot if you’re in San Mateo County and need somewhere to let your dog off-leash. The 20,000-square-foot space has separate fenced sections for large and small dogs, which matters if you’ve got a nervous small dog or one who gets overwhelmed by bigger play styles.

The ground is a mix of synthetic turf and decomposed granite, so it stays relatively clean and isn’t muddy even after rain. There are watering stations throughout, which is helpful on warm days, and waste bag dispensers are everywhere so you can actually keep things tidy without hunting around. The fencing is solid and well-maintained, which gives you that peace of mind when your dog is running around.

What makes this park work for hanging out is that there’s real seating—including shaded areas if the sun gets intense—plus restrooms nearby. You’re not stuck standing in the heat while your dog plays. The open grassy sections give dogs genuine room to run and play, and the place draws enough regular visitors that you’ll usually find other people there. If your dog is social, you’ll likely end up chatting with other owners and might even line up playdates.

The surrounding Boat Park area is worth exploring too. There are walking paths along the lagoon that work well for a leashed walk before or after the off-leash playtime, so you can make a real outing of it. The location is convenient, and the park handles both dogs that want intense fetch sessions and dogs that prefer to sniff around and take their time.
