Sacred Falls State Park (Kaliuwaสปa) is a permanently closed state park in Hauula on the North Shore of Oahu, Hawaii, managed by the Hawaii Department of Land and Natural Resources (DLNR). The park was the site of the tragic May 9, 1999 rockslide that killed 8 people and injured more than 30 others in the narrow Kaluanui Gulch. The park features the 80-foot Kaliuwaสปa (Sacred Falls) waterfall in a narrow basalt canyon, but has been permanently closed since the 1999 disaster after a USGS geological assessment confirmed ongoing extreme rockfall and landslide hazards in the unstable canyon, no legal public access exists โ the park is fenced and posted with warning signs, trespassing is strictly enforced by Hawaii DLNR officers with significant fines that increase for repeat offenses, the only legal way to view the falls is from the air via helicopter tour, the area is also culturally significant as a wahi pana (legendary sacred place) in Hawaiian culture, and the former popular 2.2-mile hiking trail through the tropical valley to the falls is permanently off-limits.
The Mother’s Day tragedy of 1999 is one of Hawaii’s worst outdoor recreation disasters โ dozens of hikers and families were picnicking and swimming at the base of the falls when massive boulders broke free from the canyon walls above, with no warning and no escape route in the narrow gulch.
WARNING: Despite the closure, many people still attempt to access the falls illegally. This is extremely dangerous โ the geological conditions that caused the 1999 disaster have not changed, and additional rockfalls continue to occur. It is also disrespectful to Native Hawaiian cultural values, as the area is a wahi pana (sacred place).
