Brown's Ranch Trailhead at 30301 N. Alma School Parkway has been closed since July 13, 2026. The City of Scottsdale is spending $1,165,599 there, paid for by the 2004 Preservation Sales Tax, on a redesigned parking lot, new lighting and roofing for the trailhead building, and a new trail dispersal area that reroutes five trail segments. The City now expects to reopen in late October but hasn't set a date.
These three months have shown how much the northern McDowell Sonoran Preserve depends on this one trailhead. The other trailheads on the north side are smaller, and three of the four the City suggests as alternates have no drinking water. The upgrade mostly goes toward what happens after you park, so the crowds that gather at Brown's Ranch can spread out across the trail system.
The full-service trailhead in the north Preserve
The City's trailhead directory lists these amenities at Brown's Ranch: parking, restrooms, shade ramadas, interpretive signage, water, horse trailer parking, hitching rails, a water trough, and the accessible Jane Rau Nature Trail. None of these are new. They were all there before the closure.
The other northern trailheads have less. Here is how the City's directory describes them, with Gateway and Lost Dog Wash added for comparison:
| Trailhead | Address | Drinking water | Other amenities the City lists |
|---|---|---|---|
| Brown's Ranch | 30301 N. Alma School Pkwy | Yes | Restrooms, shade ramadas, horse facilities, accessible Jane Rau Nature Trail |
| Fraesfield | 13400 E. Rio Verde Dr. | No | Car and horse trailer parking, restrooms, one shade ramada, signage |
| Granite Mountain | 31402 N. 136th St. | No | Car and horse trailer parking, restrooms, one shade ramada, signage |
| Gateway | 18333 N. Thompson Peak Pkwy | Yes | Restrooms, shade ramadas, accessible Bajada Nature Trail, horse facilities |
| Lost Dog Wash | 12601 N. 124th St. | Yes | Restrooms, shade ramadas, horse facilities, accessible nature trail |
When the City closed Brown's Ranch, it named four nearby trailheads as alternates: Tom's Thumb, Pima-Dynamite, Fraesfield and Granite Mountain. It flagged Tom's Thumb, Fraesfield and Granite Mountain as having no drinking water. Patch reported the same advice when the closure began in July and called Brown's Ranch "one of the busiest gateways" into the Preserve.
So Pima-Dynamite is the only alternate the City doesn't flag for missing water. Hikers who used to start at Brown's Ranch and top off their bottles at the trailhead now have to bring all their water from home, or drive to one of the full-service trailheads farther south.
Where the $1.17 million goes
The City lists three goals for the project:
- A redesigned parking lot that lasts longer, drains better and moves traffic more smoothly.
- Lighting and roofing on the trailhead building, for comfort and safety.
- A new trail dispersal area with five rerouted trail segments, meant to reduce congestion and protect sensitive areas.
The project page doesn't name the five rerouted segments, doesn't give a parking count, and doesn't describe any new shade or water. The one new feature it shows is concrete seat walls in the aerial renderings of the dispersal area. Taken together, the project is about how people move once they arrive. It doesn't promise more services.
That fits a trailhead that already had every service. Brown's Ranch never lacked water or shade. The trouble was that everyone started from the same spot and headed onto the same few trail segments. A dispersal area with rerouted connections sends people in different directions from the start. The City says this protects sensitive desert as well as easing the crowding.
What the Preserve Commission heard in September
The best public read on the schedule comes from the McDowell Sonoran Preserve Commission's September 3, 2026 meeting. The approved minutes record this from City staff:
"Browns Ranch Trailhead improvements are scheduled for completion in October 2026. Trail rerouting work continues through contracted providers."
The City has not yet announced a reopening date. The McDowell Sonoran Conservancy has cancelled its October 22 Brown's Ranch educational walk because of the construction. The City's project page shows a last update of August 5, 2026 and still gives "Fall 2026" for completion.
The same meeting covered work elsewhere in the Preserve. Staff reported that the second round of fire fuel treatment was done in July and the third is set for this fall. Staff also said they aim to present a Fire Restoration Study, done with Scottsdale Fire, in May, before next fire season. If you see crews out on other trails this fall, that's probably the fuel treatment work.
Until the gates open
The City's rule during construction is clear. The trailhead and lot are closed, and you can't park on nearby streets or in surrounding neighborhoods. The City has said it will mark any temporary access points or detours, and it posts trail maps for the South Preserve and North/Central Preserve.
Days are getting shorter, and the gates follow the sun. The City's published Preserve hours are 6:17 a.m. to 5:35 p.m. on November 1 and 6:30 a.m. to 5:25 p.m. on November 15. That's ten fewer minutes of daylight at the end of the day within two weeks, which matters if you start after work from a trailhead with no water.
The City's heat guidance still applies on warm fall days. It says to leave your dog at home if the forecast is above 90 degrees during your outing, and to turn around when half your water is gone.
The fall calendar, with and without Brown's Ranch
October is Preserve Month in Scottsdale. The Preserve has been protected since 1994 and now covers more than 30,500 acres, with over 230 miles of multi-use trails. Most October events are at trailheads that are open. Several November events are set at Brown's Ranch, so they depend on it reopening on time.
Still on for October
- October 17: Geology and ecology walk at Gateway, hosted by the Conservancy.
- October 24, 9 to 11 a.m.: Eek at the Peak at Pinnacle Peak Park, with a costume contest, a scavenger hunt, AZ Bat Rescue, nature stations, book giveaways and a DIY craft.
- October 27: A lecture on the McDowells.
- October 29 and 31: A venom walk and a Boojada walk, both at Gateway.
All month, you can pick up a youth Exploration Journal for kids up to third grade, plus a commemorative Preserve Month sticker, at any trailhead.
November, partly depending on the reopening
- November 5: Fire and ecology hike at Brown's Ranch.
- November 14: A free lecture on Scottsdale's water at Mustang Library.
- November 21: Meditation walk at Brown's Ranch.
- November 26: Thanksgiving hike at Lost Dog Wash.
The November 5 and November 21 events are the first real tests of the schedule. If the trailhead reopens in late October as the City expects, they'll be among the first organized groups to use the new dispersal area. If the work runs late, the cancelled October 22 walk is a sign of what could happen to them. Check the Conservancy's events calendar before you head out.
The Conservancy runs these programs through volunteer groups, including Guided Hike & Bike, Trailhead Ambassadors, Patrol, and Construction & Maintenance. Those are the people you'll see at the trailheads once Brown's Ranch reopens.
People who've lived near the Preserve for years know the trails well. What's changing this season is the trailhead layout. Racquel Miller follows the reopening date and the changes at the trailheads as part of keeping up with north Scottsdale. If you'd like to talk about how the Preserve's trailheads fit into your own plans, Racquel Miller is glad to help. Let's Connect.
