A devastating flash flood struck the Grand Canyon on August 29, 2026, resulting in one fatality and leaving 14 individuals unaccounted for. The sudden torrential rains, a common occurrence during the summer monsoon season, turned deadly as they swept through Bright Angel Canyon and Phantom Ranch.
The National Park Service (NPS) reported that the flash flood, which occurred around 2:30 p.m. on August 29, destroyed nearly all footbridges in its path and necessitated immediate closures and evacuations in the area. By the morning of August 30, the NPS and the Arizona Department of Public Safety had evacuated 62 people from Phantom Ranch and the lower North Kaibab Trail, with more rescues anticipated.
Park officials initially reported that 20 people were missing following the storm, but that number was later reduced to 15. Tragically, the remains of a 46-year-old man were recovered near Crystal Rapids along the Colorado River by the evening of August 30. The NPS is actively seeking information on the missing individuals, particularly those traveling the North Kaibab Trail from the North Kaibab Trailhead to Phantom Ranch, the Bright Angel Campground, or the area known as "the Box" north of Phantom Ranch.
The flash flood has caused significant damage to the area's infrastructure, including bridges and hiking paths around the inner canyon. As a result, park officials have announced that the North Kaibab Trail, Phantom Ranch, and Silver and Black Bridges are closed indefinitely. Water restrictions have also been implemented due to damage to the Transcanyon Waterline, which supplies water from the canyon for use in the park.
Beginning August 31, all park concessions have halted overnight accommodations, including the El Tovar Hotel, Bright Angel Lodge, Maswik Lodge, and Phantom Ranch. Lodging in nearby Tusayan remains open, and "dry camping" on the South Rim is still permitted. Water faucets in bathrooms are operational, and there is spigot access at the Mather Campground check-in kiosk.
Visitors are being asked to reduce water consumption in other ways as well, such as limiting showers to five minutes, turning off water while shaving and brushing teeth, and flushing toilets only as needed. No fires, regardless of the fuel used, are allowed in the South Rim or inner canyon for the time being.
The flash flood has added to what has been a challenging season for the Grand Canyon. In August 2025, the Dragon Bravo Fire on the North Rim caused extensive damage to that area of the canyon and dampened visitation to the far more visited South Rim. Overall visitation to the park fell from 4.9 million in 2024 to 4.4 million in 2025, according to National Park Service attendance records. Through July of this year, visitation was down 9% compared to the same period last year.
This year's flash flood has further impacted visitation rules for the South Rim, coming just days before the Labor Day weekend. In mid-July, President Donald Trump imposed a $100-per-person fee for foreigners visiting 11 national parks, including the Grand Canyon, with the intention of improving park infrastructure and general beautification.
The Grand Canyon community is mourning the loss of life and expressing concern for the missing individuals. The NPS is urging anyone with information on the missing hikers or backpackers to contact the tip line at 888-653-0009 or by email at nps_isb@nps.gov.
