The City's 100-Degree Trail Rule
Phoenix has a city rule that prohibits dogs on Phoenix park and mountain-preserve hiking trails whenever the temperature is 100 degrees Fahrenheit or higher. It's a real rule, not just general advice -- and given how much of the year Phoenix spends at or above 100 degrees, it effectively rules out daytime hikes with your dog for a large chunk of late spring through early fall. If you're planning a hiking trip with your dog, aim for the cooler months or very early morning, and check the forecast the day of rather than assuming a trail is open.
Camelback Mountain: No Dogs, Any Season
One trail-specific rule worth knowing on its own: dogs are prohibited on all Camelback Mountain trails year-round, including both the Echo Canyon and Cholla routes, regardless of temperature. It's one of the city's most popular hikes. The Piestewa Peak Summit Trail has the same year-round dog ban. If Camelback was on your list, our Camelback Mountain hiking guide covers what to expect on the climb -- just plan to leave your dog at the hotel or with a sitter for this one.
South Mountain Park and Papago Park: Leashed Dogs Welcome
South Mountain Park and Preserve, the largest of Phoenix's mountain parks, allows leashed dogs across its trail system -- more than 100 miles of it -- making it one of the better options for a dog-friendly hike when temperatures allow. Papago Park, closer to downtown and home to the Hole-in-the-Rock formation, also welcomes leashed dogs on its trails and tends to draw a mix of hikers, cyclists, and dog walkers on its easier, lower-elevation routes. Both parks are still subject to the citywide 100-degree rule above. See our guides to South Mountain Park and Papago Park for trail-specific detail.
Steele Indian School Park: A Dedicated Off-Leash Dog Park
If your dog needs off-leash time rather than a trail, Steele Indian School Park in central Phoenix has a purpose-built dog park with separate sections for large and small dogs, shaded areas, and drinking fountains built into the off-leash space. It's a good option when trail heat rules take hiking off the table, though the city closes the dog park for a few weeks each summer for maintenance, so check the City of Phoenix Parks page for current dates. It's a fenced park rather than a mountain preserve and isn't affected by the 100-degree trail ordinance.
Paw Safety on Pavement and Trails
Even when the air temperature is well under the 100-degree trail cutoff, pavement and trail surfaces can be dangerous for paw pads -- asphalt in the Valley can reach far higher than the air temperature on a sunny day. A simple test: press the back of your hand against the pavement or trail surface for seven seconds; if it's too hot for your hand, it's too hot for your dog's paws. Early morning is the safest window for any outdoor time with your dog for most of the warmer months, and carrying water for your dog, not just yourself, matters on any trail longer than a short loop.
Dog-Friendly Patios and Restaurants
Phoenix has a solid list of dog-friendly patio restaurants and breweries, concentrated where outdoor seating is already the norm. O.H.S.O. Brewery + Distillery in Arcadia is one of the best known, with a large canal-side patio and a standing reputation for welcoming leashed dogs -- see our Phoenix brewery guide for more on the city's taproom scene. Chelsea's Kitchen, also along the Arizona Canal, has a shaded patio that regularly accommodates leashed dogs, and multiple Postino WineCafe locations around the Valley offer dog-friendly outdoor seating. Policies and specific rules -- water bowls, leash requirements, which section of the patio -- vary by restaurant and can change, so a quick call ahead is worth it if a dog-friendly patio is the whole point of the stop.
Pet-Friendly Hotels
Lodging options span a wide range of dog policies. Kimpton Hotel Palomar Phoenix, downtown, is on the more permissive end -- Kimpton properties generally welcome dogs and cats with no size, weight, or breed restriction and no additional pet fee. On the resort end, the Arizona Biltmore allows up to two dogs of any size in designated rooms for an additional per-stay pet fee. Fees, size limits, and which rooms qualify change over time, so confirm current pet policy directly with the property before booking rather than relying on a general reputation.
