If you hike Camelback on any kind of schedule, the mountain you knew last month is not the mountain you're getting this month. Starting this week, the Cholla Trailhead on Invergordon Road goes dark for construction. Three days after it reopens, Echo Canyon closes on the other side of the mountain. Between those two dates, Camelback effectively runs on one trail at a time, and which trail that is depends on the week.

Most coverage of this has treated it as two separate closures. It isn't. Read the city's own schedule end to end and a different picture shows up: for 29 of the next 33 days, Paradise Valley's home mountain has exactly one way up.

Two Trailheads, Two Very Different Front Doors

Cholla and Echo Canyon are not interchangeable versions of the same hike. They sit on opposite sides of the mountain and serve opposite sides of town.

Cholla's trailhead is on Invergordon Road, right along the line where Paradise Valley meets Phoenix. There has never been a dedicated parking lot here. Hikers parallel park along the west side of Invergordon, and the city tows anyone who parks outside the marked sections. There's no water fountain or restroom at the trailhead itself, just a gravel path that leads to the trail. When the city rebuilt this trailhead in 2022, it did the project jointly with the Town of Paradise Valley, the Phoenix Fire Department, and the Street Transportation Department, which tells you how much this particular access point belongs to the town as much as it does to Phoenix.

Echo Canyon sits on the opposite, Phoenix-facing side, off McDonald Drive near Tatum Boulevard. It has the amenities Cholla doesn't: restrooms, benches, potable water, a small shade canopy. It also has a parking lot that fills fast and a gate that locks once it does. The city is explicit that idling on McDonald or Tatum while you wait for a spot to open up will get you a ticket, and illegally parked cars get towed.

Why Both Are Closing, Just Not at the Same Time

Cholla's closure is a sewer project. Phoenix Water Services is installing a new line along Cholla Lane and decommissioning the old one that has run through the easement south of the lane. The work crews are on site roughly 5 a.m. to 3 p.m. on weekdays, Cholla Lane is down to one lane with flaggers directing traffic, and residents along the lane keep access to their homes throughout, with occasional short delays. Water and sewer service to the neighborhood won't be interrupted.

Echo Canyon's closure, which starts right after Cholla reopens, is a different kind of project. The city is installing new automatic gates and repairing safety cables along the trail itself. The Parks and Recreation Department has said the two closures were staggered on purpose, specifically so hikers always have some way up the mountain while both projects get done.

That intent is sound. It's also what creates the squeeze most people are missing.

The Overlap Is Four Days, and It's Already Behind You Once September Starts

Line the two closure windows up against each other and the calendar looks like this. Cholla is closed August 17 through August 28, which pushes every hiker to Echo Canyon for those 12 days. Both trailheads are open from August 29 through September 1, a four-day window. Then Echo Canyon closes September 2 through September 18, which pushes everyone back to Cholla for 17 days.

Add it up and Camelback runs on a single trailhead for 29 of the 33 days between now and September 18. The four-day stretch at the end of August is the only time in the next month you can pick either trail based on preference rather than availability.

If you're planning hikes around this closure, the number to remember isn't August 28 or September 2. It's August 29 to September 1. That's the only window before mid-September when both trailheads are open at once.

Which Trail You're Actually Getting, and What That Changes

For the next 11 days, everyone climbing Camelback is on Echo Canyon, and it is the harder of the two routes. Local coverage of this closure has flagged that directly: hikers who default to Cholla for its gentler start are stepping into a steeper, more exposed climb with a boulder scramble near the top and less margin if you underestimate it.

Once Cholla reopens and Echo Canyon shuts down September 2, the traffic flips. Cholla is a slightly longer route at roughly 1.42 miles to the summit with about 1,250 feet of elevation gain, against Echo Canyon's roughly 1.2 miles and 1,280 feet. Cholla's grade is gentler on paper, but the city's own trail description is blunt that it's fully exposed with little shade, which matters more in mid-September than the numbers suggest.

The parking situation flips with it. Echo Canyon's gated lot fills by mid-morning on a normal week. During its own closure, none of that matters, but it will again the moment it reopens and absorbs Cholla's usual traffic in reverse come mid-September. Cholla never had a lot to fill in the first place. Parallel spots along Invergordon go fast, and the tow trucks are not a rumor.

The Heat Hasn't Cleared Just Because a Trail Reopens

None of this closure schedule replaces the city's separate heat rules. On any day the National Weather Service issues an Extreme Heat Warning, both trails, whichever one happens to be open, are restricted from 8 a.m. to 5 p.m. under Phoenix's Trail Heat Safety Program. In 2024, the last year the city published full-season numbers, Phoenix logged 45 days of heat-triggered trail closures between May and October, out of 121 days that hit 105 degrees or higher and 69 that topped 110.

Stack that on top of a construction schedule that already limits you to one trailhead, and the actual window for a normal mid-day hike over the next month is narrower than either schedule looks on its own. Checking the City of Phoenix's trail heat safety page before an August or early-September hike is worth the 30 seconds, especially on a week when you don't have a second trailhead to fall back on if conditions change.

Why This Matters More in Paradise Valley Than Anywhere Else

Camelback isn't a weekend attraction here. It's the thing people build their week around, the reason a lot of homes on this side of town are priced the way they are, and the backdrop that shows up in every listing photo from Lincoln Drive to Mummy Mountain. When the Town of Paradise Valley co-signs a trailhead rebuild the way it did on Cholla in 2022, that's a fair signal of how much the town treats mountain access as civic infrastructure, not just a hiking amenity.

For the next month, that infrastructure runs on one door at a time. Plan around August 29 to September 1 if you want a choice of trail. Otherwise, know which side of the mountain you're getting before you leave the house.
