Hiking With Your Dog in Maricopa County Regional Parks
Quick answer
Dogs are welcome in Maricopa County's regional parks and on their trails as long as they stay on a leash no longer than 6 feet and you pick up after them. The one exception is the Hassayampa River Preserve, where dogs aren't allowed. Good dog hikes include San Tan Mountain in Queen Creek, Usery Mountain in Mesa, McDowell Mountain in Fountain Hills, and White Tank Mountain and Estrella Mountain in the West Valley.
Last checked November 2026. Rules change, so confirm before you go.
County parks follow county rules
The Valley's mountain parks are run by different governments, and the rules change at the boundary. Phoenix's own preserves, like South Mountain and Piestewa, follow City of Phoenix rules, including the dog bans on Camelback and the 100-degree trail rule. We covered those in our post on dog-friendly hiking trails in Phoenix.
The big desert parks ringing the Valley belong to Maricopa County Parks and Recreation. Their park rules (rule R-105, Animals and Pets) say:
Your dog has to be under immediate control on a leash no longer than 6 feet. Retractable leashes run out past that, so bring a standard one.
Your dog needs a current dog license. If you're a winter visitor, our snowbird guide explains when you need a county license.
Pets can't go inside park buildings, such as nature centers. Service dogs are the exception.
Dogs can't create a nuisance, noise or disturbance, so a dog who barks nonstop at every hiker is technically breaking the rules.
You have to pick up and properly dispose of the waste.
Dogs are not allowed in the Hassayampa River Preserve, which the county protects for the birds that nest and migrate along the river.
Rule R-118 also says to stay on designated trails between trailheads. That keeps your dog out of the cholla and away from wildlife.
The county's Bark Ranger page adds that there's no extra fee to hike with your dog. From November 1 to April 30, the parks are open 6 a.m. to 8 p.m. daily.
Southeast Valley: Queen Creek, San Tan Valley and Mesa
San Tan Mountain Regional Park
San Tan Mountain covers more than 10,000 acres on Phillips Road in Queen Creek, so it's the closest county park for most of Queen Creek and San Tan Valley. The landscape changes from creosote flats to dense saguaro forest as you move toward the mountains. It's one of four county parks with a dog water fountain.
Usery Mountain Regional Park
Usery Mountain sits on Usery Pass Road in northeast Mesa. Its best-known hike is the Wind Cave Trail, which the county calls the most popular feature of the park, so expect company on a winter weekend. Usery also has a dog water fountain.
Northeast and North Valley
McDowell Mountain Regional Park
McDowell Mountain in Fountain Hills has more than 50 miles of multi-use trails across 21,099 acres. Multi-use means mountain bikes, and they can come around a bend fast. A dog who lunges at bikes will make this park stressful. It has a dog water fountain, and the park hosts races, so check the event calendar before a weekend visit.
Cave Creek Regional Park
Cave Creek Regional Park is a 2,922-acre upper Sonoran Desert park north of Phoenix. Horseback riding is one of the park's activities, so practice stepping off the trail and holding a sit while riders pass. As of this week, the county lists the nature center and trailhead restrooms as temporarily closed for a water leak.
West Valley
White Tank Mountain Regional Park
At nearly 30,000 acres, White Tank Mountain in Waddell is the largest park in the county system and the go-to big hike for Buckeye, Surprise and Peoria. It has a dog water fountain. The county lists its Trailhead Staging Area as closed for construction through November 8, 2026.
Estrella Mountain Regional Park
Estrella Mountain in Goodyear was the county's first regional park, opened in 1954, and covers 19,840 acres near where the Gila and Agua Fria rivers meet. It also has the only grass picnic area in the county park system, 65 acres of it. That lawn is a useful spot to practice loose-leash walking before you head into the desert.
Lake Pleasant Regional Park
Lake Pleasant covers 23,362 acres off Castle Hot Springs Road in Morristown. The 6-foot leash rule applies here like everywhere else in the system. The county lists the Pipeline Trailhead as closed from November 10, 2026, to March 10, 2027.
Pack for the desert, even in winter
The county's own advice for dog hikers is practical. Bring more water than you think you need and a collapsible bowl, since only four parks have dog fountains. Go in the morning or near sunset, because the desert has almost no shade. If the ground is too hot for your hand, it's too hot for paws. Turn back if your dog starts lagging, panting hard or looks glazed.
Maricopa County Animal Care and Control lists the signs of heatstroke and what to do on its pet heat safety page. For snakes, the county says to keep your dog close on a short leash, give the snake at least 6 feet and get to a vet right away if your dog is bitten.
Put a collar with ID on your dog, and make sure the microchip is registered to your current phone number.
The skills that make a county park hike easy
County trails are wide open and busy in the cooler months. On one morning loop you can pass hikers, families, runners, mountain bikers, horses and other dogs, often on narrow singletrack with cactus on both sides. A 6-foot leash only works if your dog can actually walk on it.
The skills that matter most:
Loose-leash walking on rocky, uneven ground, so you aren't pulled off balance on a descent.
A step-off and sit beside the trail while bikes and horses go by.
Calm passing of other dogs at close range, without barking or lunging.
A solid "leave it" for lizards, rabbits and whatever is under that bush.
If the hike ends with lunch, the same skills carry over to the patio. Our guide to dog-friendly patios in Old Town Scottsdale covers that next step.
Train for the trail with the Go-Everywhere Program
Mark's Go-Everywhere Program is built for owners who want to bring their dog along wherever they go. Mark starts at your house, then takes the training out to real places, like a busy trailhead on a Saturday morning, so your dog learns to handle bikes, horses and other dogs where it counts. Book a free consultation or call (602) 960-0011.
