Camelback Mountain Trail Closures: What Changes Access

On Sunday morning, a hiker made it about halfway up Camelback Mountain before her body stopped cooperating. Firefighters were dispatched to the Echo Canyon Trailhead around 11 a.m. and found her about halfway up the mountain, her core temperature past 104 degrees, and Maricopa County's helicopter Fox 1 lifted her off the mountain so crews could start cold water immersion at the trailhead. By Monday, the city had closed both of Camelback's trails from 8 a.m. to 5 p.m. through Thursday, timed to a National Weather Service Extreme Heat Warning pushing highs past 110 degrees all week.

If you hike this mountain regularly, you already know that part of the drill. Heat warning goes up, gates go down, you shift your walk earlier or later. What's different this month is that Camelback also has a second, unrelated closure running at the same time, and the two don't behave the same way. Treat them as interchangeable and you'll show up to a locked gate more than once between now and mid-September.

The Closure With a Start and End Date

Separate from any weather, the Cholla Trailhead off Invergordon Road is closed entirely from August 17 through August 28. This one has nothing to do with temperature. Phoenix Water Services is running a new sewer line along Cholla Lane as part of the Cholla Sewer Diversion and Abandonment Project, decommissioning an existing line that runs south of the road. For those two weeks, the only trail route up Camelback is Echo Canyon, off McDonald Drive near Tatum Boulevard, which happens to be the steeper and more technical of the two.

This is the closure where the standard advice actually works. Can't use your usual trailhead, use the other one. The city staggered these two projects on purpose so hikers keep some form of access to the summit throughout the work. Echo Canyon gets its own turn starting September 2, closed through September 18 for a different project involving new automatic gates and repaired safety cables along the route. Between August 29 and September 1, both trailheads happen to be open at once, a short window worth circling if you've been putting off a specific hike.

The Closure That Ignores Which Trailhead You Pick

The heat closure is a different animal. When the National Weather Service issues an Extreme Heat Warning, Phoenix's Trail Heat Safety Program shuts down Echo Canyon and Cholla together, from 8 a.m. to 5 p.m., for as many days as the warning lasts. It doesn't matter which side of the mountain you'd normally climb. Both are on the list, and so is Piestewa Peak's Summit Trail across town. Switching trailheads doesn't get you around a heat closure the way it does a construction closure, because the constraint isn't the trail. It's the mountain, at those hours, in that heat.

This week's closure runs Monday through Thursday, matching the First Alert Weather Days the National Weather Service set as a ridge of high pressure holds afternoon temperatures above 110 degrees. The program has been in place since 2021, and it isn't a rare event. In 2024, Phoenix logged 45 separate days of heat-related trail closures between May 1 and October 13, with 121 days that year reaching at least 105 degrees and 69 crossing 110. If you're building a summer routine around Camelback, closures aren't the exception. They're baked into roughly a third of the season.

Two Closures, Two Different Fixes

If You're Not Willing to Wait Until 5 p.m.

For hikers who want mid-day mileage during a heat closure, the honest answer isn't Piestewa Peak. Its Summit Trail sits on the same restricted list and closes at the same hours as Camelback. The better option is South Mountain, where the restrictions are narrower. Only the Holbert Trail, the Mormon Trail, the Hau'pal Loop Trail, and National Trail access from the Pima Canyon Trailhead close during a heat warning. More than 100 miles of trail across the rest of South Mountain Park and Preserve stay open, which is the real workaround this week if you need daylight hours rather than sunrise or sunset.

Dogs aren't part of the calculation either way. Camelback prohibits dogs on both trails year-round, and Piestewa Peak's Summit Trail carries the same rule, so this isn't a closure that changes anything if you're hiking with a leash in hand.

The Signage Is Not a Suggestion

Phoenix Fire has been vocal about what happens when hikers treat closure signs as optional. By late June 2026, the department had responded to nearly 80 mountain rescues for the year, a 50 percent jump over the same point in 2025, and officials have said some of that increase comes from people who start a hike after a trail is officially closed and then need to be pulled off it. Ignoring the signs can mean fines or community service on top of the rescue itself, and this week's helicopter extraction is a plain reminder of what the closures are built to prevent.

Planning Around It

Camelback's calendar over the next five weeks looks like this: Cholla closed through August 28, both trails open weather permitting from August 29 through September 1, then Echo Canyon closed through September 18. Layer the daily heat closures on top of that, and the safer habit is checking the city's Camelback Mountain trail page the morning of, rather than assuming last week's access still applies. A hike that worked on Tuesday can be off the table by Thursday for a completely different reason.

For anyone whose morning routine includes this mountain, the rule worth keeping is simple. Know which kind of closure you're looking at before you decide how to work around it. One is about which trail. The other is about the hour.

Camelback sits close enough to daily life in this part of the Valley that most residents plan their week around it without thinking twice. When you're ready to talk about property near it, or anywhere else across Scottsdale, Paradise Valley, or Phoenix, Rami Haddad is a call away.
