Sacred Falls State Park is a state park located near Hauula on the north shore of the Hawaiian island of Oahu. The park encompasses Kaluanui gulch and the waterfalls at its end, after which it is named. The park was closed indefinitely after a fatal rockfall on May 9, 1999 in the canyon where the waterfall is located, killing eight hikers and injuring many more.
Kaliuwa’a, also known as Sacred Falls, is defined as valley, streams, and falls (Sacred Falls), Hau’ula, O’ahu. A short distance below the falls is a trough-like gouge up the cliff where the pig demigod, Kama-puaÊ»a, is believed to have leaned against the cliff so that members of his family might climb up his body and escape their enemies. The stream and valley are called also Kaluanui.
