What it means
A trailhead is where a trail starts, and in Scottsdale it is where the whole hike is organized. It is the paved lot, the shade structure, the map board, the bike rack, the water warning and, at the big ones, a restroom building. Locals name their hikes by it. “We did Gateway” means a loop out of the Gateway Trailhead on Thompson Peak Parkway, whatever trails were involved. “Brown’s Ranch at sunrise” is a whole plan in four words.
Most of the time the word means a gateway to the McDowell Sonoran Preserve, the city’s 30,000-plus acres of protected mountain and desert. The Preserve’s amenities stop at the trailhead on purpose: there is nothing behind the gate but trail. That makes the trailhead the last place with shade, a toilet and a phone signal you can count on, which is why people linger there.
The full guide to the land is the McDowell Sonoran Preserve page, and the hikes are ranked in best hikes in Scottsdale. This page is about the word and the rules that come with it.
Where you’ll meet it
On every trail recommendation, on the city’s hours page, on the road signs across north Scottsdale, and in the Gateway Loop protocols. You will also meet it in Phoenix, where the Echo Canyon trailhead on Camelback is the Valley’s most fought-over parking lot.
Where the word came from
The word is plain American English, built like railhead: the head of the trail. Merriam-Webster dates its first known use to 1948, and nobody has claimed coining it. Whatever its first use, a modern Valley trailhead is mostly parking, because nearly everyone drives to the start of a hike.
Scottsdale’s trailheads came much later, and they came with the Preserve. After voters approved the preserve sales tax on May 23, 1995, the city bought land first and built the front doors second. Lost Dog Wash, Gateway, Tom’s Thumb and Brown’s Ranch opened as acquisitions grew. Gateway’s rammed-earth building opened in 2009, and the last major one, Pima and Dynamite, was dedicated in November 2021 with long parking spaces for bike racks. The McDowell Sonoran Conservancy now lists eight trailheads, five in the north and three in the south; neighborhood access points like Quartz fill in the gaps.
The design brief was consistent: buildings that sit low, shade that works, and lots placed at the edge so the desert behind them stays untouched. Several of them, including Granite Mountain and Fraesfield, have won architecture awards for nearly disappearing.
What it is not
A trailhead is not a park entrance with a ranger and a fee booth. The Preserve has no gatehouse, no pass and no charge to park; the gate is simply locked at night. It is also not a promise of water. The restrooms at Gateway, Lost Dog Wash, Brown’s Ranch and Tom’s Thumb are restrooms, and the Conservancy tells you to bring double the water you think you need.
The fine print
Hours. The Preserve is open sunrise to sunset every day, and the city publishes the actual gate times. The earliest opening is 4:47 a.m. around June 15; the latest is 7:02 a.m. on January 1. Closing ranges from 5:20 p.m. in early December to 7:42 p.m. in early July. The one exception is the Fourth of July, when the Preserve closes at noon. There is no overnight parking and no camping, so a car left in the lot after dark draws attention.
Rules at the gate. The Conservancy’s posted rules include hiking single file to protect the desert’s soil crust, no electric bikes or scooters, no alcohol without a permit, and packing out all trash.
Heat. Scottsdale does not close its Preserve trailheads for heat. Phoenix does: since 2021 its Trail Heat Safety Program has restricted Echo Canyon, Cholla, Piestewa Peak and, since 2024, several South Mountain trails from 8 a.m. to 5 p.m. on Extreme Heat Warning days. The arithmetic of when to start and when to turn back is in turnaround time and the summer sunrise rules.
Parking. Full lots are a weekend fact from October through April. The workable answer is a different trailhead, not the road shoulder.
