Southern Region McDowell Sonoran Preserve

The southern McDowell Sonoran Preserve trailheads and associated trails remain open.

With more rain and potentially snow predicted in the higher elevations of North Scottsdale, the city closed trails and trailheads in the northern portion of the McDowell Sonoran Preserve beginning at sundown yesterday, Monday, Jan. 25.  

The City of Scottsdale says that the decision is made in an abundance of caution to protect the preserve and its trails in wet and muddy conditions.

“While snow in the desert makes for beautiful photographs, it can cause significant negative impacts to trails due to the cumulative impact of moisture from snow and rain. Wet and muddy trails are vulnerable to long-term damage from boots, hooves, and bike tires.”

City staff will continue to monitor conditions and reopen the northern region of the preserve as soon as conditions allow. 

Beginning at sundown Monday, Jan. 25, these northern preserve trailheads and associated trails are temporarily closed: 

  • Tom’s Thumb Trailhead 
  • Browns Ranch Trailhead 
  • Granite Mountain Trailhead 
  • Fraesfield Trailhead 
  • Pima/Dynamite Trailhead 
  • All neighborhood access points and trails north of Deer Valley road alignment 

These southern preserve trailheads and associated trails remain open: 

  • Gateway Trailhead 
  • Lost Dog Wash Trailhead 
  • Sunrise Trailhead 

Additionally, Pinnacle Peak Park remains open. Find updated information at
