Temporary closure of the Tom’s Thumb Trailhead to continue; other trailheads in the northern region of the Scottsdale McDowell Sonoran Preserve set to reopen

The Tom’s Thumb Trailhead and surrounding trails will remain closed on Wednesday, Jan. 27, due to continued snow conditions on the north-facing slope of the McDowell Mountains. City of Scottsdale staff will continue to monitor conditions and will reopen Tom’s Thumb as soon as conditions allow.

While Tom’s Thumb remains closed, the other trailheads in the northern region of the Preserve that had temporarily closed will reopen for normal hours of operation on Wednesday, Jan. 27. The snow has melted, but wet conditions may still exist.  The City asks all Preserve users to be respectful of the trails beneath them.  Wet and muddy trails are vulnerable to damage from boots, hooves, and bike tires.  If you are leaving tracks, it’s too wet. Please stop and turn around.  The City of Scottsdale appreciates your cooperation and continued support and respect for the Preserve. 

Trailheads opening on Wednesday, Jan. 27 include:

  • 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 have remained open:

  • Gateway Trailhead
  • Lost Dog Wash Trailhead
  • Sunrise Trailhead

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