Hiller Dog Park occupies a generous stretch of Hiller Park’s grounds in McKinleyville, just east of Highway 101, adjacent to soccer fields and a community center. The park features two separate fenced areas—one for dogs under 25 pounds and another for larger dogs—each with grass and decomposed granite footing that drains well after coastal rain without turning muddy. Mature trees provide shade, a rarity at many dog parks, and water stations sit inside each enclosure so you don’t need to carry a bowl from your car. The terrain is relatively flat with good sightlines from most spots, making it easy to monitor your dog. Parking is ample and directly at the entrance.

Dogs can run off-leash throughout both fenced zones with no size restrictions within their designated areas. The park is free and operates during daylight hours. Early mornings draw the most regular visitors, while late afternoons bring younger dogs and their owners fresh from school. The small-dog area works well if your senior or toy breed gets anxious around larger dogs like 60-pound labs, though the separation creates two distinct social scenes. Summer weekends attract the biggest crowds; winter visits require a windbreaker since coastal exposure means conditions can shift quickly from calm to breezy.

Most owners keep sessions to 30-45 minutes and rotate out, which helps maintain manageable energy levels throughout the day. The park draws a steady mix of regulars and occasional visitors, with the morning hours bringing a quieter atmosphere and the after-school window bringing more activity. The two-zone layout means you can choose based on your dog’s size and comfort level with other dogs on-site.
