Lovely trail, pretty rough, but then I was going down. Right now, February 2020, it's shut because of the work being done on the Manoa Falls Trail, into which this trail debouches. That final section is a muddy mess that's (again) closed and difficult to traverse.

Great hike close to Downtown Honolulu. Definitely moderate for most of the trail, but the loop trail may be considered hard. There were 2 steep sections on the ridge with ropes. The ridge trail is very narrow and over grown but manageable. Watch out for holes, it’s narrow and steep in places. I would agree that counter clockwise is best. The views on the ridge are beautiful. Segments were quite muddy.

Loved this trail, even doing it in heavy rain the views were spectacular. Counter clockwise is the way to go. Its almost impossible to find the turn off going clockwise. If you are sure footed and not afraid of heights the views on the ridge are worth the hike. The one rope spot others have mentioned is pretty scary, but the ridge is not super difficult. It's just really narrow, with a definitive drop off on one side. Be cautious!

Do the loop counterclockwise! I did it clockwise and the steep ledge with frayed ropes was pretty scary going down. It was a fun hike with *beautiful* views at the top. The turns in the trail are very easy to miss, as they are overgrown and unmarked. The connecting ridge trails to the West have more forgiving terrain, but just as nice surroundings as the upper loop. Like everyone said, up to Manoa Falls it's very busy with non hikers, but once you branch off it's pretty isolated. Overall, good hike, but I'll probably focus on the connecting trails on the ridge next time.

Good hike! Did 7.5 miles in total. The point where you turn right on the loop is hard to find unless your paying attention to the map. We missed it the first time. Views are great on the ridge! Not too over grown or muddy today.

Awesome side trail to the incredibly crowded Moana Waterfall trail. Enjoyed the serenity of the wind blowing the bamboo into each other. making for a beautiful natural radio!

This trail goes from easy, to moderate, to hard. the trail to the waterfall is quite easy. Then you turn and start climbing and it becomes moderate untill you reach the overlook. From the overlook it becomes a ridge trail and get much more difficult. My husband and I have done some "hard" rated trails here in Oahu and they weren't quite like this. At one point in the trail you had about 6 inches of path as you skirted around/ climbed the peak. There was a rope to help you, but this is where my husband put his foot down and said no, so we turned around. Overall, we really enjoyed the trail. Very buggy and very muddy.

Let me start this saying I had fun. This was a great experience for me. I hiked solo. The trail was very muddy. I would never attempt it without proper water resistant shoes with good traction. Up to the final loop was a decent, moderate hike. You are going up hill and it's not easy, but nothing too strenuous. You will climb throug banyan tree roots so that is fun (no sarcasm, it was really cool). Now for the loop at the end. First, this hike is tagged as kid friendly. the upper section of the last loop is NOT for children. In many sections the trail is overgrown and you cannot see where you are stepping. It requires a lot of concentration and you are very close to the edge. I am an experienced hiker and I had trouble in some spots. It was a challenge, and I was looking for one. So this hike was great for me. I am not trying to scare anyone away. My hike was nearly 7 miles and took me about 4 hours. I highly recommend following the advice in all the other reviews and if you are going to do the loop go counter clockwise. I went clockwise and missed the turn off twice and I had a GPS and trail map telling me where to go. If you make it to the final loop and go either right or left you will get some amazing views before the hard part starts. and you can always double back. So don't be afraid, just be prepared.

Easily one of the more enjoyable routes Ive done. I didnt see another person on the trail until I was nearly back to the trailhead. Bring lots of water, wear long pants to avoid scratches.

Very muddy and slippery, would advise hiking shoes as running shoes would get soaked and stuck in the mud.

Amazingly beautiful trail, even the touristy parts up to Manoa Falls were supergreen and pretty. The ridge and rope-y parts were a little scary, don't go alone and definitely do the loop in the counter-clockwise direction. Look forward to lush bamboo forests, lots of roots, some scrambly-stony parts, lotsa mud and a long slow beautiful ridge-walking part. Stunning views of the valley and of Honolulu reward you!

Fantastic Trail, the Manoa Falls part can be congested with non-hikers but avoid some frustration with an early start. 0700 was quiet. Trail passes though many small micro climates and foliage that are very cool and the hike on the Ridge loop is amazing, with views of Diamond Head and Waikiki. Best to complete counterclockwise as there is on steep sketchy area with frayed ropes that I would definitely not want to descend on but up isn’t an issue on a dry day. Otherwise completely passable for any sure footed hikers. Took approximately 2:30 with lots of photo breaks. Feel free to DM questions @corc19 on IG

Did this trail after the Moana waterfall. Didn't complete the loop, but hiked it just before it branch's off and had to turn around due to time. I would love to go back and complete it. It was raining heavily during the whole hike, so the use of bamboo sticks helped a lot on the way back, four of us left those bamboo sticks at the trail entrance for others to use.

This was very fun! The hike up to Manoa Falls is easy, with a beautiful waterfall, and then this side trail (there’s a sign to the left hand side if you’re hiking up to the falls) is so beautiful and peaceful! There’s a few switchbacks, but the elevation gain is pretty steady, there’s no sharp inclines. Then, when you get to the loop, it’ll say “Pauoa Flatts Trail” with an arrow going both ways. I would highly suggest going to the RIGHT and going counterclockwise unless you want to descend using a rope on the side of a mountain with a steep drop. Going up with the rope was much more pleasant than descending in that spot! Also, after turning right into the loop, it’ll only be about 10 minutes until you come to a spectacular view of the valley, and even a small part of Kaneohe Bay & Honolulu on clear days. The loop is very fun-it is a ridge trail, but it’s not super steep in any spot for a long time and is definitely manageable! We enjoyed this hike very much! The views are incredible and the rain forest is gorgeous. The loop took us about an hour and a half (with a lot of stopping to take pictures), the whole 5.2 mile hike took us about 4 hours, going a very comfortable pace.

Quiet trail away from the more populated Manoa falls trail with a beautiful view once you make it to the loop at the top. Would recommend old shoes because yours will get very muddy

Nice hike! Took about 2 hours total coming in from Manoa Falls. Nice to get away from all the tourists.
