Rancho Cucamonga's Sapphire Falls Was Supposed to Reopen. A New Order Just Pushed That to 2028

Ask around Rancho Cucamonga long enough and someone will eventually ask you the same question locals have been trading for over a decade: is Cucamonga Canyon open yet? The honest answer, as of a new federal order signed this summer, is no, and it won't be until at least mid-2028. That answer surprises people, because for the past couple of years the story going around town was the opposite. The land was supposedly bought. The trailhead was supposedly designed. The reopening was supposedly close. None of that turned out to be quite right, and understanding why tells you something real about how this canyon actually works, not the postcard version.
Cucamonga Canyon, the drainage that leads up to a waterfall locals call Sapphire Falls, has been closed to the public since 12:00 a.m. on August 23, 2013, when the U.S. Forest Service shut it down for public safety and fire risk. At the time, that felt like a temporary measure. Instead it became one of the longest-running trail closures in the San Bernardino National Forest, and the story of why is less about wildfire and more about what happens when a hike becomes famous on social media before anyone builds the infrastructure to handle it.
The hike itself explains the danger. Reaching the falls historically meant a four to five mile walk through the canyon that included a descent down a roughly 50-foot cliffside, sometimes using informal ropes or tied-together blankets, plus multiple water crossings, ending at a waterfall some visitors then tried to climb. Crowds swelled in 2009 as the location spread online, and by 2013 the canyon walls were layered in graffiti, rescue calls were spiking, and the U.S. Forest Service made the call to close it entirely.
What kept it closed for over a decade wasn't just caution. It was geography. The historic access point sits near Almond Street, in a residential neighborhood where Rancho Cucamonga backs directly into the foothills, and that single street is also the main way emergency crews and residents get in and out. Every rescue meant fire and police resources pulled away from that neighborhood to hike in after someone who'd gotten stuck or hurt. Every weekend crowd meant parked cars clogging the only road out. The canyon's problem was never really about the trail. It was about who else has to live with the trail's traffic.
In April 2024, the story shifted toward optimism. ABC7 reported that the city of Rancho Cucamonga had secured $2.6 million in state and federal funding to purchase more than 120 acres of private land, with the goal of building a proper trailhead and parking lot that would route visitors in safely, away from the residential streets that had absorbed the traffic for a decade. City spokesperson Jennifer Camacho said that if everything went as planned, completion was anticipated for 2025. A city advisory posted not long after put a specific date on the closure itself, stating the canyon, including Sapphire Falls, would remain closed until May 2026 under the Forest Service's order.
That May 2026 date is important, because it's the one a lot of residents have been counting down to. It's also the date that just quietly stopped being true. In July 2026, the San Bernardino National Forest issued a new closure order for the Cucamonga Canyon area, and this one is not a placeholder. It's effective from July 13, 2026 through July 13, 2028, and it covers the same closure boundary that's kept the falls off limits since 2013. Rather than the canyon opening this year as the earlier timeline implied, the Forest Service just locked the door through the summer of 2028.
That's the piece that hasn't fully landed yet in local conversation. The land purchase everyone heard about in 2024 addressed the access problem. It didn't address the federal closure itself, and those are two different processes that don't automatically sync up. Buying the land for a safer trailhead is a necessary step. It is not the same thing as the Forest Service deciding the underlying wilderness area is ready to reopen.
The neighborhood tension that shaped this closure hasn't gone away either. When ABC7 talked to residents living near the proposed new trailhead in 2024, the reactions split along familiar lines. Joggers and cyclists who remembered the canyon fondly wanted it back. Paul Beardsley, a Rancho Cucamonga resident out running the trails, called the area "a wonderful wilderness area back there" and said more people should get to experience it. Others weren't as sure.
"A lot of people are concerned about the parking issues, people coming up here, leaving trash and staying overnight," said Tatiana Fakhoury, who lives on Skyline Drive.
That's the same concern residents have voiced since at least 2014, when the city briefly experimented with a paid parking reservation system on Almond Street, charging non-residents between $15 and $25 a day depending on season while residents parked free with proof of address. That system existed for the lower portion of the canyon, below the Sapphire Falls closure line, and it eventually faded as enforcement challenges and neighborhood pushback continued. It's worth knowing that history exists, because it shows the current trailhead plan isn't the first attempt at a controlled-access compromise. It's at least the second, and the first one didn't stick.
While the closure order and the trailhead plans have moved at government speed, one part of the canyon's story has been consistent the whole time. The Cucamonga Foothill Preservation Alliance, a local volunteer group, has spent years going into the canyon to remove graffiti and haul out trash, work that started not long after the 2013 closure gave them access without the crowds. The group has also become the city's go-to partner for handling recovered native California sagebrush, which is protected under state law and periodically stolen from the foothills for resale. When rangers or deputies recover stolen sagebrush, it's handed over to the CFPA, which donates it to a local tribe.
None of that cleanup work reopens a federally closed canyon on its own, but it's the reason the canyon isn't in worse shape than it was in 2013. If and when a trailhead finally does open, it will be opening onto ground this group has spent over a decade trying to restore.
If you live here and you've been holding out hope for Sapphire Falls this year, the honest move is to redirect that hope for now. A few options nearby actually deliver a similar payoff without the closure order hanging over them:
The lesson in all of this isn't that Rancho Cucamonga's government is dragging its feet. It's that a federal closure and a city infrastructure project run on separate timelines, and a headline about secured funding doesn't mean the underlying order has changed. The next time you hear that Cucamonga Canyon is finally about to reopen, the useful question isn't whether the city has a plan. It's whether the Forest Service has actually issued anything that says so. Right now, the paper trail says otherwise, through the summer of 2028.
