The public is reminded that Naohia Falls (Kalihi Ice Ponds) is located in a watershed area managed by the Honolulu Board of Water Supply (BWS). Contrary to posts found on social media, blogs, and various websites (hiking, travel, local activities, lifestyle, health and wellness, and general interest), Kalihi Ice Ponds (Naohia Falls) is not a hiking trail and road is closed and not accessible. There is no legal access.
Anyone attempting to reach the ice ponds would be trespassing and subject to citation by the Honolulu Police Department. The land surrounding Kalihi Ice Ponds (Naohia Falls) supports Oahu’s fresh water system, which supplies the drinking water resources for more than 1 million people on island. As such, BWS does not permit access of any kind so that the watershed stays pristine. Those cited are required to make a court appearance and may face fines up to $2,000, community service, and/or up to six months in prison. As you plan your outdoor activities on Oahu, please respect the island’s fresh water resources by not intruding onto protected watershed land. Announcements regarding closures of or conditions on public trails managed by the State of Hawaii may be found online at hawaiitrails.hawaii.gov.
Illegal access increases the watershed's exposure to invasive species and diseases spread by humans and animals hiking the land or swimming in the water, litter and biological waste that gets left behind, and accelerated forest degradation due to soil erosion. It will take each and every one of us working together to protect our natural resources for today and the future. Please respect Oahu's local fresh water resources by not intruding onto protected watershed land. Mahalo for your kokua.
Residents and visitors may enjoy the beauty of the Hawaiian islands on one of the many legal hiking trails that are available to the public. Announcements regarding closures of or conditions on public trails managed by the State of Hawaii may be found online at https://hawaiitrails.hawaii.gov/.
