Fairview Park in Costa Mesa spreads across 208 acres of bluffs, vernal pools, and native plants along the Santa Ana River, making it a genuinely pleasant spot for hiking with your dog. The well-maintained trails wind through the park with enough variety that you won’t feel like you’re doing the same walk twice. You’ll see wildflowers, small waterways, and plenty of shade from mature trees—handy when you’re out in Orange County heat.

The trails themselves are the main draw here. They’re easy enough for a casual morning walk but substantial enough if you want real exercise. The landscape changes as you move through different sections, so even regular visitors find something new to notice. Leashed dogs are welcome throughout, and the flat terrain makes it accessible for dogs of varying fitness levels.

Beyond walking, the park has some quirks worth knowing about. There’s a model aircraft flying area, so you might see RC planes overhead. A miniature train also runs through the park on weekends during certain seasons, which can be either a fun bonus or something to be aware of depending on your dog’s temperament around noise. Summer Concerts in the Park happens here too, which draws crowds but also means a festive atmosphere if you time your visit right.

The park has picnic areas scattered throughout with shade, and that’s the best place to take a break and let your dog rest. Bring more water than you think you’ll need—the open terrain doesn’t offer much relief from the sun on hot days. The parking area is straightforward, and you won’t spend time hunting for a spot even on moderately busy weekends. Waste bags are essential, as cleanup is expected and taken seriously here. The Santa Ana River Path connection gives you trail options heading both directions if you want to extend your outing.
