ʻĪao Valley State Monument

UPDATE 7/2017: We now anticipate that ʻIao Valley SM will reopen in EARLY AUGUST 2017.

While the adjacent Kepaniwai Park operated by the County has reopened, ‘Iao Valley State Monument remains closed as the State works to complete repairs to to make the park safe for public visitation in the wake of major flooding. Interim slope stabilization has been completed, but State Parks is still completing parking lot restriping, installation of flexible traffic delineators, and installation of security guardrail fencing at various locations in the park. Repairs to the pedestrian bridge will round out the interim improvements.

A second significant phase of slope stabilization will be required later in the year. We anticipate an additional park closure during that phase of work.

‘Iao Valley State Monument suffered heavy damages from flooding in late 2016 and is closed until further notice for public safety reasons. The anticipated reopening date is August 2017. Damage assessments, clean-up and repairs are ongoing. Please be aware that if you are found within the closed park it is a violation of HAR 13-146-4, which is a petty misdemeanor punishable by up to 30 days in jail and a fine of up to $1,000.
