***UPDATE: Alright. I redid this hike and even I had a hard time figuring out where to go so I…read morefigured I should update this review with more details!*** Whoever bothers to listen to TLC, you're missing out completely. Waterfalls are meant to be chased, especially after Tropical Storms and heavy rain! (Just don't be dumb and hike during those dangerous conditions.) Located deep into Kalauao Valley in 'Aiea, this hike showcases the raw beauty Oahu has to offer. This trail is located off of the well-known 'Aiea Loop trail. Make your way to Keaiwa Heiau State Recreation Area and park on the second level parking once you enter the camping grounds. There, you'll see restrooms and the head of 'Aiea Loop Trail. Be sure to lock your vehicles and not to leave any valuables. Start heading onto the 'Aiea Loop Trail (park opens at 7:00am FYI). Within about 15 minutes of walking along the Loop trail, you'll come across your first fork. Take the LEFT fork. It's a pretty obvious fork. Follow the ribbons. The next fork is a little less obvious. If you see a tower for power lines, you're heading in the right direction. Keep going past the power line tower. You'll seem like you're headed straight (not going down yet.) It'll seem like you are just staying on the ridge for quite a while, but just look for a pink little ribbon hidden on the right side. You'll see a mango tree (which there's a few) but you'll take a RIGHT this time (kind of like a U turn.) The mango tree has a pink bottle cap on it as well as carvings in the trunk (LANZ.) Once you see this mango tree on the right, make almost like a U turn and just keep following the trail which takes you down, down, down into the valley. It's steep, could be wet, just be careful. There's a portion that you can use a rope. It's up to you. Once you hear the stream, you'll follow it as it leads you to the falls. You can cross the stream as many times as you see fit. We found it more difficult going there and probably crossed nearly 7-8 times but on the way back, we crossed about 3-4 times. Just be on the lookout for ribbons on your side. If you see them, there's a high chance you'll have to cross and you'll see the ribbons on the opposite side. Some mentioned passing a "wrong way" rock, but we didn't see this. Just keep following the stream and VOILA, you've made it to the falls. There's a short path that leads you to the lower and upper tiers of the falls. If you jump, just be careful. There's been quite a few hiking accidents on the news lately. Better be safe than to be on the news. On the way up, it's pretty steep and can be extremely exhausting. Take breaks as needed. Honestly, we went on a day that actually rained that morning. We didn't find the hike to be extremely muddy or slippery. In fact, I thought it was relatively safe compared to some of the ridge hikes I've been on. Total hiking time (including a 15 minute stop at the falls): just under 3 hours. I believe the hike is approximately 3.5-4 miles. Tips: 1) Wear long pants or long socks. If you want to jump in the pool, bring a change of clothes. 2) Bring extra socks/shoes/slippers in your car. Your feet will probably be wet by crossing the stream. 3) If pants or long socks aren't your thing, bring mosquito repellent. 4) Bring water because you'll want it after that trek back UP the valley. 5) Go slowly until you find each fork. 'Aiea Loop Trail isn't the most exciting so you don't want to end up doing that!

A beautiful and not too difficult trail (this is for the Moanalua Valley Trail, not the back way to…read moreStairway to Heaven--I didn't go that far). It has a wide walking path and you can go for quite a while before needing to turn back. I did 4 miles in and 4 miles back and it was a great workout. Not too much incline, but enough to make you feel like you accomplished something. Beautiful views and there were hardly any other people on the trail, even on a Saturday. Don't park in the nearby Moanalua Park to do this trail. Park street-side and walk the short distance up.

I actually haven't really enjoyed this park as a park proper because I simply transit through it to get to the hiking trail (also the campsite appears to be closed off), but it has enough amenities that I was left impressed. There are benches to sit with overhead shelters. Bathrooms helped me clean up after I got caught up in mud along the trail. The sinks were outside the lockable portion, so running water is always available thankfully. There are places to sit and be in community with the gorgeous trees around. I heard the Oahu Amakihi at this altitude even, which was a pleasant and rather welcome surprise. The park warden is a self-described grumpy old man, but he was responsive and helpful when I knocked on his door to report a water leak at the entrance of the Aiea Loop Trail.

I was surprised I haven't written a review for Keaiwa Heiau State Park but maybe I did and the…read moreYelp Ghost stole it! Anyway this is the park that you enter in order to get to the Aiea Loop Trail with breathtaking views from the coastline thru the beautiful Halawa Valley with H3 smack in the middle. The Heiau is well marked and as a Hawaiian Spiritual place it is noted that it is to be respected as such. When you enter the park the Heiau is immediately on your left and parking in marked stalls is required. There are restroom facilities next to the covered pavilion and walkways from one to another. The path to walk into the Heiau is uneven and not easy to access so watch your step if you intend to walk around. I've seen feral chickens, feral pigs, feral cats and campers here. Permits are required for the campers not so much for the aforementioned animals. Dogs are required to be on leash. Beautiful and cooler temperature wise. The drive up Aiea Heights Drive isn't as perilous as others comment about but you do need to pay attention.

This is one of my favorite hikes to do on this island. It was my second time completing it and I…read morewould definitely return!! The first time, the falls were dry so we were pretty bummed. But, the second time, the falls were gushing and had perfect clear water to jump into. I would say the hike to mildly challenging. There are spots that require concentration and focus so you don't fall. If it's muddy, it is way more challenging too. It can be confusing in some spots because it goes off two different ways but if you ask someone, you can figure it out easily. Along the trial, there are many beautiful views and spots for photos. And of course the falls are gorgeous. Highly recommend

This is a ridge trail which includes drop offs on both sides although the trail is fairly wide as ridge trails go. The trail climbs up the ridge going down then up starting through forest and then onto a more exposed trails. The trail was slick in places so we wore crampons especially for downhills. Going up the trail you will see Mānana Trail sign to left and waterfall to right. Parking is in a residential area, so keep your voice down. Make sure to bring plenty of water, hats, sunscreen especially on a sunny day. I wore long tights, the ferns are scratchy. Started early to keep from being in sun at the heat of the day.

3.5 stars Okay so,…read morefirst off, THE TRAIL IS SUPER LONG. roughly about 14 miles roundtrip or maybe 16 if you go to see the Haiku stairs. The trail itself isn't all that visible and it's pretty dangerous. and obviously, don't stand too close to the side bc there are false ledges. Definitely BRING GLOVES because there are ropes along the way during some of the narrower parts of the trail and you could easily get cut and then possibly an infection from touching the dirty rope if it cuts you. Also, don't use the railings to support yourself because they're very old and they'll probably break with some pressure. Bring lots of water and snacks because this hike will take a longg time. Some parts may be muddy if you go in the early morning or after it has rained. The view was very nice being able to see all the greenery and tree tops in the mountain. It's a fun hike if you're with people that are fun and make sure everyone knows what theyre getting into because again, this is a super long hike.

ʻAiea Loop Trail is a birder's dream and my current favorite trail on Oʻahu. I don't know how much…read morethe Yelp community intersects with the birding community, but I was drawn to ʻAiea Loop Trail because of the eBird app. I heard both the ʻApapane and the Oʻahu ʻAmakihi on my first trek here, but I did not get to photograph them properly for ID purposes (let alone for aesthetic photography). It was on my second trek on the trail that I was able to get up high enough to video record both the ʻApapane and the Oʻahu ʻAmakihi. It was a magical moment, cut short because I started my hike too late. It was also on this second trek that I also heard what I believe to be the Oʻahu ʻElepaio. I have yet to see it or photograph them, but I believe in the rare bird rule of second attempts: I hear these birds before I see them, and I see them before I can photograph them (naturally). I have to return as soon as I can. If you aren't a birder (yet), there is still a lot to be gained from hiking this trail. The views of valleys full of greenery are simply gorgeous. Perhaps a given because Hawaii, but rainbows appear everywhere here. The trail is better maintained comparatively, and the loop isn't too long, although I accidentally started the loop too late and did not know how long it actually was until I completed it. I was so scared I was going to get stuck on the trail after nightfall, but thankfully I got out before dusk. Mosquitos are still a nuisance here, so be prepared.

After two heavy rain storms that caused flooding in the Islands some areas of the hike had whole hill sides that had numerous trees down. The trail is only passable because of the hard work of the parks crew. In normally shaded areas there is more because of this.

You need to gain access to the trailhead as it is in the military housing behind Tripler Hospital. Fortunately, my hiking buddy works for the military and we were able to get to the trailhead with no problems. There was ample parking and appears to be fairly safe given that this is on military area. So while I wouldn't recommend leaving your car unlocked, the chances of your car getting broken into is pretty slim. Going up the paved path is pretty straight forward. Just make sure you take the HECO road on the left once you're on the "trail." The incline is steady and you're quickly admiring views of Oahu. We went around lunchtime so the sun was overhead and shade was a bit scarce. I can imagine that once the guavas are ripe, the air would smell guavaey lol. So it was a relief to get to the end of the paved area, do some drone shots and go back down. We would definitely go again to do the full ridge!

This new trail is a walking historical trail around the island, you will see so much and learn about Ford Islands historical past by walking this trail. The trail is mostly paved and all you have to do is follow the blue dots around which are placed every ten feet and makes navigating the trail easy. Every few hundred yards you will come across information boards that explain the area and discusses a bit about the history but military as well as Hawaiian. The designers really did a great job because the trail is well maintained and information boards are located around the island to assist with the history of the island which includes the crucial role Ford Island played for the military over the years and early sugarcane farming. The trail is great for families, kids, bikes, pets and if you stop and take in the great views and read all the history, you will be glad you did. Start early and bring a hat, sunglasses and of course water because it does get warm. Hope you all enjoy this new addition to Ford Island.

I love that there is no traffic or exhaust to breath in. Just you and the beauty and tranquility of a historical location. I always make it a point to stop at the USS ARIZONA marker to pray for those who gave their lives for our freedom. Even those of the enemies who lost their lives as well. During COVID my husband and I did the Marine Corp. Marathon here since it MCM was allowing virtual times to complete the race on the day of the race. So I got to check that off my bucket list of runs. But hopefully one day I will make it to DC to be a part of the MCM experience. What I would like to see on this trail are more benches to sit and relax at and a playground for children to play on, a volleyball playing area, and even Cornhoe and horseshoe pits near the Navy Lodge. A great place to bring your dogs as well. Three separate areas that are gated for different size dogs near the Navy Lodge. Navy Lodge does have a bathroom you may use. Please be respectful and ask to use it, then keep it clean as you leave. Enjoy!
