After a Stormy Late Summer, Where Do Aiea's Two State Parks Stand This Fall?

If three tropical systems passed near Oʻahu in about six weeks, why has the ʻAiea Loop Trail been open all fall? Lala's rain wasn't what closed the trail in August. The problem was a damaged piece of power equipment. Once Hawaiian Electric replaced it, the trail reopened, and the two storms after it brought no new closure notice for Aiea. So this October, Aiea's two state parks are shaped mostly by gates and crews: a 6:45 p.m. gate up in Aiea Heights, and down at the shoreline a 5:30 p.m. gate plus about two weeks of construction.

What Actually Closed Keaīwa in August

Tropical Storm Lala's rain fell over Hawaiʻi from August 14 to 16. By UH News' August 20 analysis, Honolulu County got 5.5 inches of rain on August 16, with a peak Oʻahu wind speed of 39 mph. On that same day, the Honolulu mayor's office reported gusts over 40 mph, steady rain and saturated ground, and said it expected trees and branches to keep falling.

Keaīwa Heiau State Recreation Area wasn't closed for tree cleanup. A state update dated August 23 said the park and the ʻAiea Loop Trail would stay closed until at least August 28 while Hawaiian Electric repaired a high-voltage transmission structure the storm had damaged. The Star-Advertiser's report explained how the repair would be done:

"To comply with Federal Aviation Administration regulations and Hawaiian Electric's safety practices, the helicopter will not fly over residential or populated areas while carrying loads, according to the company."

Hawaii News Now reported that the repairs were finished, the helicopter had helped crews replace the structure, and the park would reopen Friday, August 28. The same report said downed trees could be seen throughout the park and safety signs were posted at the entrance. The public record shows the closure in place by August 23 and over on August 28. No source found here gives the date it started.

Since the closure came from a power line, the park opened again as soon as the line was fixed. That timing is why the downed trees came up only in passing.

Two More Storms, No New Notice for Aiea

In September, Tropical Storm Nolo and Hurricane Lowell put the Division of State Parks back on storm footing. Its Important Park Notices page lists island-wide closures on Hawaiʻi Island and Maui, and partial reopenings on Kauaʻi, in its September 23 and October 5 updates. On Oʻahu, the October 5 and October 8 updates name one storm-damaged park, Kaʻena Point State Park, where vehicle access is closed and the Keawaʻula Trail stays shut because of road damage. Neither update lists Keaīwa Heiau or the ʻAiea Loop Trail.

A DLNR release dated September 30 said all Oʻahu forestry and wildlife lands were open after Nolo. The exceptions it listed were on other islands.

The only Aiea item on that notices page this month has nothing to do with weather. It is a construction notice for ʻAiea Bay State Recreation Area.

The Clock Up the Hill

Keaīwa switched to winter hours the day after Labor Day. The gate is open 7:00 a.m. to 6:45 p.m. until summer hours return April 1, when closing moves to 7:45 p.m. Entry is free.

DLNR describes the ʻAiea Loop Trail as a 4.8-mile loop with 900 feet of elevation gain along the west ridge of Hālawa Valley. It suggests allowing about 2.5 to 3 hours. Work backward from the 6:45 p.m. gate with a three-hour hike and you need to be on the trail by about 3:45 p.m. The steep switchback and stream crossing come at the end of the loop, so a late start puts the hardest footing in the last, darkest part of the walk.

A few details from the state's own pages are easy to forget between visits:

• Parking: marked stalls at the upper trailhead, next to the parking lots, picnic pavilions and a restroom.
• Dogs: not allowed in the park itself, but leashed dogs may pass through the park to reach the trail.
• Footing: DLNR warns of mud and exposed roots, and its trail pages mention no post-Lala inspection. Those warnings matter more after weeks of downed trees and saturated ground.
• Emergencies: a resident caretaker lives near the front gate.

Along the loop you pass a series of landmarks. Keaīwa Heiau sits at the park entrance. DLNR calls it a heiau hoʻola, a healing temple where kahuna treated illness and trained students in laʻau lapaʻau, medicine using plants, fasting and prayer. Its stacked rock wall, about four feet high, encloses an area of 100 by 160 feet. Foresters replanted much of the area in the late 1920s. That planting is the source of the lemon eucalyptus scent and the Norfolk Island pines at the lower end of the trail. Native koa and ʻōhiʻa appear near Puʻu Uau, the high point about halfway around, and some hikers spot remnants of a B-24 bomber that crashed in 1944. On the ridge, the views reach from Pearl Harbor and the Waiʻanae Range to Honolulu and Diamond Head.

The morning end of the schedule is the easier one to use. With the gate opening at 7:00 a.m., a full loop leaves time for the Pearlridge Open-Air Farmers Market. About 30 vendors set up there Saturday mornings from 8 a.m. to noon in the Wai Makai street-level lot along Kamehameha Highway.

Down the Hill, a Scheduled Disruption at ʻAiea Bay

ʻAiea Bay State Recreation Area runs on a shorter day than its neighbor up the hill: 7 a.m. to 5:30 p.m. every day, free, with picnic areas, views of Pearl Harbor and the Arizona Memorial, and the Pearl Harbor bike path running through it.

DLNR's notice says construction started there October 5 and should take about two weeks. Restrooms stay open, but parking is limited. If the work runs two weeks, it would wrap up around October 19. The notice gives an estimate, not a firm end date.

The notice doesn't describe the work. State procurement records show two ʻAiea Bay jobs this year, both marked "Awarded" on HIePRO: the pavilion reroof and the general repairs with ADA sinks. One, a scope dated May 19, 2026, covers new corrugated roofs on the pavilions and comfort station, along with flashing, underlayment and a new roof vent cap. Comfort-station materials are to be handled as hazardous. The other is a general-repairs package: ADA hand sinks in the men's and women's restrooms, concrete slab repair, asphalt removal and repair, root removal and restriped parking stalls. A revised proposal for that job also lists walkway repairs. DLNR hasn't tied either contract to the October schedule, so these are the likely jobs, not confirmed ones. Asphalt work and restriping would fit with a notice that limits parking.

Here is how the two parks compare this month:

The Campground Question

Keaīwa's campground is still the one item without a clear answer. HIePRO lists a $1,733,548 award to JBC Engineering & Construction, LLC for ADA campsite improvements: tree removal and grading, concrete walkways, campsite paving, tent pads, retaining walls, signage and furnishings. The estimated contract dates run from May 26, 2025 to March 22, 2026. Those dates are estimates. They don't confirm the work is finished.

The park's page contradicts itself. A December 23, 2025 notice says the campsites are closed for construction through February 2026. A December 12 notice says reservations for February 1, 2026 and later are open through Explore Outdoor Hawaiʻi. Further down, the camping section still reads "TEMPORARILY CLOSED." When the page was written, it described 10 tent sites available Friday through Wednesday, at $20 a night for residents and $30 for non-residents. Anyone planning a night up there can check the reservation system or call the State Parks office in Honolulu at 587-0300 before relying on the page.

The heiau has a steady caretaker of its own. DLNR's partner roster names the Paʻi Foundation as the site's curator, running maintenance workdays, educational groups, cultural events and restoration planning.

Later this month, Pearlridge holds its free Candy Crawl on Thursday, October 29, from 5 to 8 p.m., with indoor trick-or-treating in Mauka and Wai Makai, a keiki costume contest and PBS Hawaiʻi entertainment, according to Honolulu Magazine's Halloween roundup. ʻAiea Bay's gate closes at 5:30 p.m. and Keaīwa's at 6:45 p.m., so the Candy Crawl runs after both parks have closed for the day.

Questions about Aiea often go beyond trails and gate hours. They can be about how the hill and the shoreline fit into daily life, or about what a move nearby could look like. If you're thinking it through, Alicia Fu is happy to listen and help you sort out a next step. Let's Connect.
