Well maintained trails, some phenomenal overlooks. Things can get a little muddy (its Hawaii).Bring bugspray for the lower portions of the trail.

Sometimes slippery overall moderately easy hike with amazing views.

Nice liesure treck, lots of nature, spectacular views and a surprise from H3

Amazing Ridge Hike! Also a nice loop trail if you are looking to do something less strenuous. Beautiful views of the city and ocean along the way. If you do the ridge hike, be prepared to have to break the trail a bit the further you go. Some very narrow areas with ropes, so you need to pay attention. Worth the amazing views!

Great park and hiking area. However, there are a limited number of parked stalls, so if theyre full, you may as well come back another day. My friends and I (and probably 20-30 other cars) parked along the side of the road near the trailhead. It looked like a safe, legal area to park and we were not blocking anything. Still, we all got parking tickets. Where we parked, there were no signs that said no parking. There were only some small signs in front of the parking stalls that said park only in marked stalls. When there are cars parked in those stalls, those signs are barely visible unless youre on foot or already parked in those stalls. Most people driving past probably wouldnt be able to see them. It felt sneaky and misleading. The city probably made $1000 in tickets that day

Really fun trail! Its not too difficult and its pretty cool up there. I went with my wife and we had lots of fun. It has a lot of good views. You can even see the pale highway.

We tried to camp here for the night in our stay at Oahu, unfortunately the light and the rain got the better of us and we stayed the night in the car instead. For campers – there are a some toilets and showers located here, but FYI you have to bring your own charcoal to cook food! Theres not too many pictures of the campsites available so Ive done my best and taken a few of them. Hopefully thisll help all campers out there!

Nice, enjoyable hike, except the last quarter, too muddy, and too uphill after the long trek.

Its clean and well maintained. The hike is simple and nothing adventurous. Simple hike, just a beautiful view of the state highway.

Relaxing and peaceful environment and views...

Great place to relax and just enjoy nature

This is one of the best hikes on Oahu. Cool and breezy on a warm, sunny day, theres lots to see. Big jungle trees, moss, ferns, lehua blossoms, downed aircraft from WWII. Wow! 4.25mi loop with just one short .25mi steep uphill climb.

Camped over night on the state recreation area. Place was clean and tidy. Great views, wildlife and quiet. Easy access to the Aiea Loop trail.

Keaiwa Heiau sits at the top of Aiea Heights Road in Aiea. It is a very popular park for hikers, tourists, kahus, picnickers, dog walkers, campers, and anyone who wants to meditate in a peaceful setting surrounded by tons of trees, birds, and calming energy.We frequent the heiau often and my husband uses the pavilions to conduct his Reiki, Hakii, Sportsbetting classes, healing sessions, and psychic readings. Some halaus use the park for hula and other things. The pavilions on weekends are very popular so go early if you want to reserve one. The park opens at 7 a.m. but sometimes the caretaker will open up a bit earlier.Bring tablecloths if you want to picnic there because the feral chickens poop on the benches and tables. We always have pareos to cover the seats and tables and we also bring a bottle of hand soap since there isnt any soap to wash your hands with there. Id give it 5 stars if the tables and benches were hosed down periodically, but it never happens that Ive seen.Other than that it is a lovely place to visit and relax. Please be respectful and do not play around in the heiau itself. That is the area with the rock wallks. Do not move the rocks, leave things in the heiau, or otherwise disrespect it. This is a sacred area and should always be respected.

Pretty place, need a little bit of sprucing up. People hiking and enjoying the picnic areas, parking area full.

Great hike above H3. Just a little over 4.5 miles. Not too difficult.

Aloha Green cleans fun HistoricalTakes my breath away they where Photography of a Childs One YearBirth it was so natural peacefulHikers hugs from me 2 U from Hawaii

Good for hiking. Sometimes muddy, sometimes not. Lots of chickens.

Love this hiking trail!! Great view of the H-3 from the top of the trail

Nice shady 5 mile hike. Dog friendly

Fun hike beautiful views can get a little slippery so be safe

Aiea Loop is an amazing hike. Rated as moderate but I would say its pretty easygoing!

For camping it is a pretty nice place. there’s a designated place for a fire, not so dirty toilets, cold showers.the campgrounds are pretty roomy. some are under trees and others on flat land. there’s no view of the city from the tents.

A very nice short hike - beautiful scenery

Home to Aiea Loop Trail. Sign says it is 4.8 miles... They lied, its 6. The state should mark the trail bc there are other cut offs that could get you lost. Nice scenic views. My kids did this hike 5 and 3 years old. Some muddy spots but overall easy hike.

Can easily hiking for seniors ... (^.^)

Super fun hike! It was very pretty at the top where you could see the H-3. You could also see one of the planes that crashed during WW2 which I thought was amazing! Definitely would go again, and would recommend to others who have 2-3 hours to kill. It was a long hike, but definitely pays off. Ive heard that during summer or fall theres tons of guavas!

A beautiful hike. Take the loop trail, or for a greater challenge you can head up toward the ridge trail from the top of the loop.

The park is good, the loop trail is a great trail for those that want to sweat but not get over exerted. Ive hiked it 3 times now and I love it.

Did the Loop Trail with Loretta and two of our neices. Did it 55 years ago when I was in the 6th grade. Got to see what was left of the Japanese aircraft that went down during the attack on Pearl Harbor in 1941. Back in 1964 it was still a plane but today its just sheets of metal.

Nice recreation area for outdoor sporting.

Hands on you get to see and feel the metamorphosis of rock/lava into an iron rich earthen clay

Beautiful Ridge hike, great for exploring. Gorgeous plants and a well maintained park. Short trails or longer options available.

Great family trail. Hawaii No Ka Oi!

An amazing place to hike with the family. And geocache.

Scenic cool. Good workout

Great place to stretch your legs, while hiking an excellent trail. Big Mahalo to D the property manager in charge, your years of overseeing (over 2 decades) show in the care and conduct you afforded to us on our trip.

Its a pleasant, moderate hiking location. There arent many views from the hike, but it is still enjoyable.

Nice little hike!

The Aiea Loop is a decent trail. Easily followed, but kind of crowded.

What we saw of the park was beautiful. The man in charge of taking care of the park was awful and sadly ruined our experience

So peaceful and beautiful. Good place to take your lunch and eat up there. Born and raised and still live in Aiea, never get tired of this place.

Beautiful long hike. Not too hard but if youre scared of heights dont go. It gets pretty scary in a few spots. Kids loved it.

Small with picnic tables and restrooms. Most people visit for the trailheads to the Aiea Loop Trail. Free entrance and free parking.

Serene place of significant spiritual importance to Native Hawaiians. There are signs asking that the site be respected and left as it is found.

Beautiful views

Always love hiking the Aiea Loop Trail. A great routine!

So close to the city but such a peaceful getaway to enjoy nature in Honolulu.

Fun hike, but need to be in shape 5 miles of lots of hills. Spectacular views..

Great place for pics if you are visiting or local to the area. A must see.

Its a beautiful historical landmark. Theres a trail to hike, a beautiful heiau, and a small pavilion to eat and rest. .

Not a difficult hike but, fairly long roughly four miles, the hike can be very muddy depending on how much it has been raining and the scenery​ is very nice.

Shows some of the beauty of Hawaii. Breathtaking views.

Great views and fresh air

Nice easy hike

Its a beautiful sight scene

Was drier than expected, and so beautiful.

This was the most amazing hike Ive ever been on. You can hear and see many different kinds of birds along the way and the plant life changes significantly depending on your elevation. Best of all, the views are absolutely breathtaking.Its not too bad in terms of a challenge but I imagine its quite treacherous if its been raining, with all of the clay. Its mostly shaded and had a pleasant breeze.

This is one of the best kept Heiaus I have seen on Oahu. Please remember to be respectful and bring your offering.

Great hike, very easy, suitable for dogs, kids, older folks, everyone. View is unbeatable. See for yourself :)

I love this area. Close to my house. Some parts of the year get guavas. Eucalyptus trees make the air smell good. Just feels good to get outside.

Very well kept and beautiful park!

Always a nice getaway during the routine daily grind...

Nice area featuring the Aiea loop trail and a picnic area

Great running trail, also has facility at the beginning of the trail

A great leisurely hike that is perfect for beginners with an amazing view at the end.

Great to hike the Aiea Loop trail in the morning.

Great place to hike...

Always love going here cuz its peaceful and cool

Great hike. Great view

Fulfilling hike and not busy.

I love going here... Camping and hiking trails

Love hiking here perfect for all families to enjoy

Great trail, easy to follow, easy to hike.

Very nice and peaceful location. A lot of photographers use this area for photoshoots as the lines of trees and shaded lighting look great in photos. Its also a popular spot for hikers and people who want to hang out in a park. Parking is tough and very limited. The park staff are nice enough to drive around the park before they close to remind you to pack up before they close the gate.

I run this trail a few times a week. I guess Im a little biased but it is my favorite.

Very easy yet long hike. I would recommend doing the trail in reverse because it seems the hardest part is right at the tail end of the hike. Cellular reception is also great even amidst the forests ups and downs.

BEAUTIFUL up there!

Nice views. Clean

Serene! Beautiful Views.

Beautiful place for a hike.

Great hike. Sketchy people cruising in the parking lot so dont leave any valuables in your vehicle.

Nice views when driving.

It’s not a hiking trail and wasn’t made for that. It was made from Hawaiians and you would be killed if you disrespect. Take a rock home from anywhere of Hawaii to the mainland and you’ll get badluck!

Great hike with beautiful views.

Beautiful as always

This is a sacred Hawaiian Heiau, so please give it the respect it deserves. Its beautiful serene place where you can hike, camp, and picnic.

Its rated as moderate but it was super easy!!

Aiea Loop Trail is a lovely, easy hike and well worth a couple hours off your time. Friendly for family hiking and hiking with the doggo.

Moderate to easy hike. Well marked and great views under a jungle Canopy

Great trail, very well maintained and marked.

Fun day hiking with the family. The total trail is 4.4 miles, which is too much for us. Its a pretty trail with a lot of beautiful views. Its also muddy and can be slippery. It can get a little rigorous, so bring enough water. Be sure to bring a plastic bag and slippers for after the hike.

Power spot

Loving this place, Calm, relaxing park with amazing bird sounds; hens, roosters running about. Best prepare with bug repellent. Nice spot for a quick drive into nature to get away from the city life also great picnic area. Love the way it drizzels and the sun is still out. Truly a nice piece of paradise. Havent hiked yet but I am sure it wont be disappointing. Enjoy. Please ask permission to the spirits to enter the Heiau if u are going to go in . Be respectful as it is their home and dont touch anything. Also dont go to the far right back, as it is a even more sacred spot. Then when u come out give thanks for going in. This is a great spot for healing energy. Mahalo.

Please keep it clean

Great hike and not very difficult with some great views of downtown and pearl harbor

An easy loop with amazing views!

Great hike!!!

5 mile hike through pure heaven. No insects is always a plus!

Great family hike. Not too hard, but not too easy as to make it boring. Beautiful views of Halawa Valley
