Today is August 10. If you're going by Arcadia News's reporting on the Phoenix Water Services Department's construction timeline, Cholla Trail closes today and stays closed through August 21. If you check the City of Phoenix's own Camelback Mountain trail page instead, the closure doesn't begin until August 17 and runs to August 28. Same trail, same sewer project, and an 11-day gap between two sources that are each, in their own way, official.
For anyone in Paradise Valley who treats Camelback as the backyard gym, this kind of scheduling fog isn't a new experience. The mountain's two summit trails have spent the better part of a decade being closed, rerouted, and rebuilt in response to injuries, erosion, and neighborhood disputes that have nothing to do with hiking difficulty ratings. This month's sewer work is just the latest entry in that pattern, and understanding the pattern is more useful than memorizing any single closure date.
What the Cholla Sewer Project Actually Closes
The work itself is straightforward. The City of Phoenix Water Services Department is running the Cholla Sewer Diversion and Abandonment Project, listed under project number WS90500320, and Cholla Trail has to close while crews work. During the closure, the city's guidance is to use the Echo Canyon Trailhead at 4925 E. McDonald Dr. in Paradise Valley instead. Questions go to 602-235-2488.
Here's where the two accounts diverge:
| Source | Closure window | Construction start |
|---|---|---|
| City of Phoenix, Camelback Mountain trail page | August 17-28, 2026 | Not listed |
| Arcadia News, citing Phoenix Water Services | August 10-21, 2026 | July 13, 2026 |
Arcadia News reported that construction on the project began July 13, with the trail closure itself running August 10 through 21. The city's official trail page lists the closure a week later, from the 17th through the 28th. Neither page cites the other, and there's no visible correction on either one. If you're planning a hike on Cholla this month, the safest move is to call the number the city lists before you park, because right now the trail might already be closed, or it might still be open for another week.
This Isn't Cholla's First Disappearing Act
The trail has a history of vanishing for reasons that have nothing to do with plumbing. In March 2020, a 300-pound boulder rolled onto a hiker's legs on Cholla Trail, and firefighters had to use special equipment to free him before taking him to a hospital for extensive lower leg injuries. The trail stayed closed for over two years while the city worked out a bigger problem underneath the injury: the old trailhead required hikers to park on Invergordon Road and walk up Cholla Lane, a residential street, to reach the trail. Neighbors on that street had been living with foot traffic that reportedly reached over 10,000 hikers a month, enough that many were walking in the road itself rather than staying on a defined path.
The fix took until September 30, 2022, when a rebuilt trail reopened with a new alignment off Invergordon Road that bypassed Cholla Lane entirely, along with a restroom and drinking fountain that hadn't existed before. Getting there required agreement between the Phoenix Parks and Recreation Department, Street Transportation Department, Phoenix Fire Department, and the Town of Paradise Valley itself. The trailhead residents use today is, in other words, the third or fourth version of this same trail in the last decade.
The Mountain Doesn't Hold Still After Storms Either
Construction schedules aren't the only thing that moves the goalposts. Camelback sits inside Arizona's monsoon season, which runs from June 15 through September 30, and the mountain's granite and exposed rock don't handle sudden moisture well. In 2025, rangers closed Echo Canyon Trail, the other summit route and the one Paradise Valley residents are being routed to this month, for about two months after spotting erosion and shifting boulders following storm activity. It reopened in December.
Emmanuel Salifu, an Arizona State University professor who studies soil and rock behavior in extreme conditions, put the underlying problem simply. Arizona's heat dries and cracks the ground, dust storms strip away loose particles, and rain then seeps into the gaps it created.
"You could still have some saturated areas where a hiker's weight might just be enough to cause failures."
Today's date puts us squarely inside that season, with seven more weeks of monsoon risk ahead. A single heavy storm over Camelback this month could trigger a precautionary closure on Echo Canyon that has nothing to do with the sewer project on Cholla, which means the detour route itself isn't guaranteed to stay open either.
Where Residents Are Rerouting This Month
Whichever closure date turns out to be accurate, a few options are worth knowing before you need them.
- Echo Canyon Trailhead, 4925 E. McDonald Dr., Paradise Valley 85253, is the city's official detour while Cholla is down. It comes with its own constraint: the parking lot fills by late morning on weekdays and stays full most of the day on weekends, and once it does, the entry gate closes. Idling on McDonald Drive or Tatum Boulevard to wait it out isn't allowed, and police will ticket or tow.
- Piestewa Peak's Freedom Trail, a 3.5-mile loop in the Phoenix Mountains Preserve, sits a short drive west and offers skyline views without Camelback's trailhead bottleneck.
- Papago Park's Hole-in-the-Rock, southeast of Paradise Valley, is a short walk through red sandstone formations rather than granite, and it's a reasonable substitute on a morning when the heat or the crowd at Camelback makes a longer summit attempt less appealing.
- Tyner's Trail on Mummy Mountain is the option most residents don't know exists. It's reached through the grounds of the Camelback Inn off Lincoln Drive, and it's the only developed public-adjacent trail on a mountain that's otherwise ringed by private homes and dead-end cul-de-sacs. The trail sits on resort property, so checking in before you park is the polite move, but it delivers a view of Camelback from the opposite ridge that neither Echo Canyon nor Cholla can offer.
The Mountain as Infrastructure, Not Just a View
None of this is really about a single trail closing for two weeks. It's about what Camelback actually is to the people who live around it: a piece of shared infrastructure that gets renegotiated among city departments, resort landowners, and residential streets every few years, not a fixed backdrop that just happens to be photogenic from the pool deck. The boulder incident forced a redesign. The redesign took two years and four government bodies to finish. The monsoon closes trails on its own schedule regardless of what any city page says. And this month, even the paperwork on a routine sewer project can't settle on a start date.
Staying current on which gate is open this week is, for a lot of Paradise Valley residents, just part of living this close to the mountain. Valley Luxury Group pays attention to these details because we live with the same trail schedules and the same mountain views as our neighbors. If the way this neighborhood keeps shifting has you curious about what else has changed, including what your own property might be worth in today's market, we're glad to talk it through.
