This is a beautiful trail. I love the trees and terrain. I got some beautiful pictures. Just very serene for me. It was muddy in a few spots but not too bad today. For me this was an easy hike but I’m an avid hiker, hike recorded at 4.8 miles with 1335 elevation gain. There are som narrow spots but not too bad. Nice morning hike.

This was a great hike! You go through all different types of forest and terrain including a lot of pine trees and a lot of stairs both natural by roots and built stairs as well. The view at the top is breathtaking if it’s not foggy which can happen a lot in the area.

Fun, moderate trail to the ridge. The final stretch has rope work and is fairly steep but only for a short little while. We started with a group of about 14 but then only 5 of us made it to the very end. Even if you don't hike the full length, the views are worth the hike and you can turn around at any point since it's an in/out trail. This trail connects to Ka'au - would love to come back one day to go up this trail then come down Ka'au side. Final note: keep an eye on the weather in the days before doing this hike, there are parts that would essentially turn into mudslides after heavy rains.

Hardest hike I have done...1 ridge climb. Made it to the top which was socked in... very muddy today. But a great day!

Nice trail but really muddy . . Beautiful view of h3. . Took us about 2 hours going at a casual speed . . Definitely better with hiking shoes . . Not a hard trail but narrow paths might make it difficult for young kids . .

Great hike and challenging. What makes it hard is the steep decline with the muddy wet areas. However retiring was faster, but more strenuous due to using leg muscles allot. The water fall was great and there are cliffs where you can jump into the pond.

It is a very easy, kid/dog friendly hike. Surrounded by lots of trees. A hike I would recommend for family day.

A great trail! Bring the family and pets on this one! Be respectful of this trail there is memorial for soldiers who died in this forest. The views of the H3 and pearl harbor from the top are well worth the trek. Be careful if it has recently rained , the trail can be quite muddy! Bring lots of water. Hiking shoes highly recommended.

Very beautiful, easy to follow, breathtaking view when you reach the summit.

Beautiful hike with amazing views at the top. Super muddy and slippery during the final stretch, but completely worth it. We recorded nearly 5 miles in just over 2 hours along this trail.

the hike isn't hard but the rating hard for me comes from the arch itself.

I would I say I'm a pretty good hiker and have hiked way dangerous ones than this one but don't under estimate the arch. If you go up the arch go back down the same way you came up and then use the trail on the right to go under the arch(there is one on the left I heard about but didn't see it ) I saw that there was a little edge area on the right near the top that could access the trail under the arch DONT go this way, I tried to jump from here needless to say lost my footing and got scratched up quite a bit from the fall. It was pretty sketchy because of the incline and the loose rocks on the trail below. Please head my advice and use the trail to the right .

otherwise great little hike and experience

Nice hike a little warm when we went today around 1000. It is a moderate hike with a lot of switchbacks, but some amazing views on top and during the climb. The climb past the pink pill box is along a ridge for a very short distance and is not for those with a fear of heights. It was moderately trafficked on a Saturday probably less trafficked on a weekday.

Go early! We got there at 9am and it was really hot and humid in the trail. There’s not much shade and the trail ends up feeling hotter because of the way it’s set up, they’re like hot pockets. Not great, pace yourself and definitely bring water & wear SPF. The pill boxes were really cool, the pink one you’ll need someone to boost you if you want photos on top of it. Incredible, gorgeous views. Worth it!!!

unique in that you are hiking down to a waterfall. moderately steep decline over many roots but there are plenty of ropes and trees you can hold to help you down(and back up).there's only one part that opens up for a view but mostly it's thru narrow paths with alot of tree cover and mud. we ran into a hunting party with 6 dogs who just killed a boar. pretty awesome. don't forget to bring a swimsuit to swim at the waterfall.

Hiking the 3.5 miles to the first peak, Ka’inawa’au Nui Summit, is peaceful and beautiful. I went during the week and only saw one other person the entire day. As mentioned many times before, DEFINITELY wear pants. Mine were pretty much destroyed by the time I was done but better them than my legs. However, the reason I feel compelled to write this review is to give a heads up about the last part of the trail, the section from the Ka'inawa'au Summit to Lanipo Summit...
I DO NOT recommend hiking this part of the trail unless you are a very experienced hiker! It is EXTREMELY overgrown, so bad that I wasn't even sure there was a trail there at all and had to use my hands to clear away vegetation the entire time just to be sure that my foot would land on earth, and not thick roots disguising a sheer drop off the side of the mountain. This, and the fact that the ridge is very narrow, very steep, and the winds can be very strong up there make it extremely sketchy. Also, the plants are so overgrown that their are vines constantly wrapping around your ankles and threatening to trip you as you make your way, which adds another element of danger to the mix.
The views from the first summit are beautiful, and getting there is quite an accomplishment in itself, and although clouds and wind rolled in while I was making the final ascent to Lanipo Summit, I cannot imagine that the views could have been any better than at Ka'inawa'au had it been clear. Unless someone does some major clearing of the trail, it is simply not worth the danger and difficulty to do the last part in my opinion.
This being said, the rest of the trail has spectacular views from the beginning, and a nice mix of ascending and descending sections that help you not get too worn out during the 7+ mile roundtrip hike.
The whole thing is overgrown though, so just be extra diligent about only stepping on the path because some sections offer a false sense of security when actually there is a small area that is solid ground.
Overall it's a moderate hike until the very end, and really nice, but I regret attempting the final quarter mile section and highly recommend sticking to the first summit.

Absolutely breath taking and rewarding! The trail is very prominent and easy to follow. This trail really shows off the diversity of the Hawaiian ecosystem, the trail goes through so many changes of venue with regard to plant life as you hike the switchbacks up to the knifes edge Ridgeline, looking down on the most beautiful rain forests and blue ocean. You’ll constantly catch yourself turning around for a peak at the view, wondering when the summit will arrive; trust me when I say that YOU WILL KNOW WHEN YOU GET TO THE TOP, it is unmistakeable and gorgeous.

Climbing the upper section can be slippery and muddy, also look out for the tree root systems that canvas the ground because these are super slippery on decent; otherwise, it’s very manageable for any age other than the fact that is long and steep. I recommend starting super early with the intent to summit for the sunrise, the trail is very easy to navigate by headlamp. Have fun!!!!

It’s a hike! Moves you through lower island trees to a pine forest and then the last stretch puts you into the rain forest. The last third is very steep but the view is worth the effort (if the fog lifts).

the trail splits at the very beginning giving you the option to go down or stay up. I would recommend going down then take the top on the way back. I went with my 15, 10 and 8 yr olds. it was a little challenging because the trail was slippery but we made it!

While it's a short hike, it is a challenge. getting up to the ridge takes some navigating. We started up the top of the arch decided against it. The gravel up the right side was super slick. Don't trust any rock not to come loose. Test handholds and footholds. All that said, it was one of the coolest hikes on the island! Views were breathtaking!

Awesome! Muddy and slippery but worth the trip!

Literally my fav hike eva holy shat so fun, I like jumped and stuff, there where like trees there. Overall the water was nice. Muddy too. Outdoors is cool. Recommend for people over the age of 77.

Love this hike. Moderate for sure especially when wet. Falls were not really running too much in June. Rope swing always fun

Great trail ... I ran it in just under an hour. It was muddy and I fell once. If you walk at a moderate pace expect to take a couple hours.

Amazing hike ... we went early (on the trail by 7 AM) and had the falls and swimming hole to ourselves for 40 minuets before the multitudes started arriving.

Great hike. Some areas are pretty steep and lots of stairs. Worth every step for the amazing view at the top. Went early so avoid the increase number of hikes later in the morning.

Waterfall and swimming hole is worth it. Had fun jumping off the ropes. Not much to look at on the actual hike though. Pretty muddy so be prepared for that. Fairly easy hike overall.

My wife and I loved the challenge of the root and rock wall that we encountered. We definitely learned we needed more water for the hike! Being new to the area it was really nice to see the nature around us. The waterfall was beautiful and the were two areas where you can swim and jump off the rope swing or rocks. Will definitely be doing this trail again!

I didn’t get to finish the hike because I brought my black lab when we went to hike this in the afternoon. The trail was too hot for our lab. She started laying down to get her feet off the trail dirt. Recommend doing this in the mornings if you plan to bring your pets! Will be back to get to the pillbox, looks pretty cool from the bottom

When I first reached the waterfall, it was more of a trickle; however, I decided to wait for a bit and it steadily increased. Definitely worth the hike down here.
