Almost everyone’s first McDowell hike is the Gateway Loop, and it should be. But the McDowell Sonoran Preserve is roughly 30,500 acres with more than 230 miles of trail, and Gateway is one door. Locals rotate. Here’s the rotation, and which trail answers which question.
One piece of geography first: Pinnacle Peak Park is a separate city park, not part of the Preserve, and it plays by stricter rules. We’ll get to those.
Pinnacle Peak: the best short hike in the city
Pinnacle Peak Park is 150 acres wrapped around the 3,169-foot granite spire that names half of north Scottsdale. One trail, 1.75 miles each way, well built, moderately steep, with interpretive signs and a staffed trailhead. It doesn’t summit — the final pitch belongs to rock climbers — but the views from the high saddle, out over Troon and the boulder fields, are the whole prize.
The rules are tighter than the Preserve’s: sunrise to sunset, with rangers sweeping the trail before the gate closes, and no dogs and no bikes. The park only exists because the city spent years fighting to restore public access after development shut the public out in the mid-1990s; it reopened in 2002.
The lot is tiny and fills by about 7:30 AM from November through April, but it turns over fast. Wait in the line rather than parking in Troon, where the tickets are enthusiastic. Better yet, go an hour before sunset on a weekday, then drive five minutes to Talavera at the Four Seasons for the sunset itself.
Tom’s Thumb: the hard one
Tom’s Thumb is the most serious thing the Preserve asks of an ordinary hiker: about two miles and roughly 1,200 feet of exposed switchbacks from the trailhead on 128th Street to the saddle below a 140-foot granite monolith on the ridgeline.
Two things catch people. There is no drinking water at the trailhead, so fill up at home. And the descent is what wrecks knees, not the climb. From December through March the lot is full by 7:30 AM on weekends; be parked by 7:00, or come after 2:00 PM and climb into the afternoon light.
Marcus Landslide: the one with a story
From the same lot, turn the other way. The Marcus Landslide Trail runs about 1.5 miles each way on wide, gentle tread, plus an optional 0.7-mile loop up onto the debris. The debris is the point. Roughly half a million years ago, the face of East End — the high point of the McDowells — broke away and ran about a mile, leaving the second-largest known landslide in Arizona. Nobody recognized it for what it was until 2002, when two ASU graduate students on a field trip worked out why the boulder field didn’t make sense.
The interpretive signs genuinely improve this one, and it’s the best family option at the trailhead. Do the outbound leg early. It’s downhill going out and uphill coming back, which is the wrong way round when it’s hot.
Brown’s Ranch: the connoisseur’s trailhead
If we had to pick one trailhead to live next to, it’s Brown’s Ranch, up Alma School Parkway north of Dynamite. The trails are flat to gently rolling crushed granite through the densest saguaro forest in the system, past the rusted leftovers of E.O. Brown’s cattle operation, which ran to about 44,000 acres. There are restrooms, water, shade, and the barrier-free half-mile Jane Rau Interpretive Trail, named for one of the volunteers who talked the city into buying all of this.
Because there’s so little climbing, Brown’s Ranch stays walkable later into a warm morning than any mountain route, and after a wet winter it has the best wildflowers in the Preserve. Head out Brown’s Ranch Road, the old ranch two-track, wide enough to walk two abreast. If the lot looks full, the Fraesfield Trailhead is ten minutes east and usually empty — but it has no water.
Lost Dog Wash: the evening walk
At the Preserve’s southern end, off Via Linda near Shea, Lost Dog Wash is the after-work standard for east Scottsdale. The trails are gentle by McDowell standards, and the destination is the Taliesin Overlook, about two miles each way, looking down on Frank Lloyd Wright’s winter camp at Taliesin West.
Take the Ringtail Trail out, which keeps you up on the slope with the views, and drop into the sandy wash for the walk home. Start about ninety minutes before sunset in the cooler months: the range behind you goes orange while the city lights come up in front.
Choosing, quickly
- Visitors with one morning: Pinnacle Peak.
- The fit friend who wants to suffer: Tom’s Thumb.
- Kids, grandparents, or geology nerds: Marcus Landslide.
- A long, easy day, or a bike: Brown’s Ranch.
- After work, October through April: Lost Dog Wash to the overlook.
- A parking war at Gateway: the Quartz Trailhead, five minutes south, where the lot is rarely full and there are no restrooms, so plan accordingly.
The house rules
The Preserve’s trails are free and open sunrise to sunset. Dogs are allowed on a leash in the Preserve (not at Pinnacle Peak), bikes and horses share most trails, and the etiquette is the same everywhere: uphill has the right of way, stay on trail, and carry out everything you carried in. From May through September, every hike on this list is a first-light hike, run by the summer sunrise rules. And if something with scales is sunning itself across the trail, the desert wildlife field guide covers what to do next, which is mostly nothing, from a respectful distance.
Why any of this is here
None of these trailheads was inevitable. The north end of the city was headed for rooftops and fairways until Scottsdale voters taxed themselves twice, in 1995 and again in 2004, to buy the desert instead. That story is worth reading on a rest break. Every trailhead here is a return on the investment. Collect.
