McDowell Sonoran Preserve
- Avoid outdoor activities all together, or schedule them for the early morning hours.
- Drink plenty of water before and during your activity.
- Communicate with someone when and where you will be hiking/riding.
- Wear loose-fitting, light colored clothing.
- Leave your dog at home, as they are not able to cool themselves by sweating and can quickly be overtaken by the heat.
TOM'S THUMB TRAILHEAD WILL BE CLOSED JUNE 26
Due to trail maintenance, Tom's Thumb Trailhead will be closed all day on June 26. It will re-open on June 27. We appreciate your patience. This will give you an opportunity to explore the other trails in the Preserve!
The Scottsdale McDowell Sonoran Preserve is a large, permanently protected, sustainable desert habitat that includes an interconnected network of non-motorized, multi-use trails (hike/bike/horse) accessed from multiple trailhead locations.
New Trailhead Improvements
The City of Scottsdale is moving forward with design and construction of improvements to three trailheads in the northern region of the Preserve.
Construction of restrooms, paved parking, equestrian staging areas and other support amenities is currently underway at the Granite Mountain and Fraesfield Trailheads. The Granite Mountain Trailhead will remain open for public use during most of the construction period, however a short duration closure is anticipated in the spring of 2019. Details will be posted at the top of this page when they are available. Please observe all posted signs, as access routes and parking areas may be temporarily redirected. The Fraesfield Trailhead will be closed to public access on weekdays and open on weekends through the spring of 2019. Construction of both trailheads is anticipated to be complete in summer 2019.
The City of Scottsdale is also moving forward with design and construction of the Pima Dynamite Trailhead located on the northeast corner of Pima Road and Dynamite Boulevard. This trailhead will provide parking and support amenities for public recreational access to the extensive network of trails in the northern region of the Preserve for hiking, biking, trail running, and horseback riding. Construction is expected to begin in 2019, and completed in early 2020.

Dogs in the Preserve are a privilege. If you bring your dog it is your responsibility to follow the rules:
- If it is over 90 degrees at any time in your hike, it's too hot for your dog.
- Dogs must be on hand held leash, no longer than 6 feet at all times.
- Waste must be pick up immediately and disposed of in a trash container or carried with you until you reach a trash container.
- Loose or bagged waste on the trail is prohibited.
Heat Warning for Dog Owners
Dogs do not actually sweat. They exchange heat through panting and to a minor degree, through their feet pads. Additionally, our canine friends do not tolerate high environmental temperatures as well as humans do.
The risk groups are much the same as humans: Old, obese, suffer from medical conditions or take medicine. Certain breeds are more susceptible to heat emergencies than other breeds. These breeds with a broad, short skull: Boxers, Bulldogs, Pugs, etc.
Causes of heat emergency in dogs:
- Strenuous exercise in hot, humid weather
- Elevated temperatures from atmospheric temps and hot surface contact
- Sidewalk/natural rock surface can radiate very high temps
- 90 degree atmospheric temp/ potential surface temp of 135 degrees
- Begins with heavy panting/signs of difficulty breathing
- Tongue/gums appears bright red with thick saliva
- Skin elasticity (when pinched, does not snap back)
- Worsens if dog vomits, becomes unsteady, lethargic, unwilling to move (Core temp in the 104 degree range)
- lips/membranes become blue/gray
- Rapid on-set collapse, seizure, unconsciousness and death
What to do
- Immediate cooling of body with water, cool packs to groin, where legs meet the body, neck
- Remove from heat immediately
- Get to Veterinarian (Consequences of heat emergency = kidney failure, heart irregularities, other system failures, death)
- Know your dog’s limitations/abilities
- Assess the environmental conditions
- Carry plenty of water for both you and your dog
- Cool vests and trail booties for dogs are available and are very efficient
