By far the best hike I’ve done! You instantly start the hike in the beauty of the rainforest. A few back and forth a over the river, climbing, and finally you get to the first waterfall. From there the ropes are your best friend the rest of the hike. It was raining so we were definitely muddy and wet and we’re still able to climb safely. There and plenty of foot holes and places to rest if needed. The 3rd waterfall is the longest but worth it! We only went partially up the ridge due to wind and low visibility. It’s very slippery on the ridge as well. That plus finishing the loop trail, it took us 5.5 hours. I will definitely be back. It is a full body workout! If it’s raining I suggest shoe spikes for the ridge.

Awesome hike. Finally went around the whole crater which made it a nice loop instead of out an back. Worth it for sure.

Had my garmin watch following on GPS. It recorded the entire trip as 6.54 miles. It was 2.6 to get to the crater once you climb up the third waterfall. It was about another 2 miles around the crater. We rejoined with the main trail after coming down the ridge from the crater at 5.8 miles.

It took me and my gf about 5.5 hours. We did it at a leisurely pace stopping at all the waterfalls and also took dip in the stream. It was raining at the top which made it super slow going. It gets a little slippery at the top with all the mud.

Really fun experience. Make sure you have enough time to finish. Shoes with tread help. I skidded twice in my worn out running shoes. Wouldn’t wear them on this hike if I went again. Upper body strength helps if you’re planning to do the crater.

I felt like I was in Fern Gully!!! It was gorgeous, surreal, and a good hike! Can be a bit slippery so wear good shoes and be ready to be in awe!!!

It’s starts beautiful as there are amazing views of the rainforest and it’s fauna, but as the trail continues it gets tight with far too many people on this trail and the views never live up to the opening scene. We found our family standing and waiting 8-10 minutes due to traffic on the trail, yikes. I find the trails of Lyon Arboretum far more rewarding just above Manoa falls trailhead.

Left for the trail at about 11 AM right after it rained, then had to pay 5 dollars upfront to enter the trailhead and there was still plenty of parking space available. Because it had just recently rained there was lots of mud which made the rocks we were climbing on slippery. The hike itself was about an hour of steady hiking with a beautiful waterfall at the end.

Nice hike but way too many people on small trail.

Enjoyable, Easy, and worth it at the end!

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.

Did this last week, great hike, awesome pictures.

Great hike. Second waterfall is the best. You’ll be in the clouds around the crater depending on time of day. Great views.
5.4 miles, 3 hours without a pack or water, minimal stopping and some light jogging. Wear Trail running/water shoes with good grip as it’s extremely muddy, slippery, and you will have to cross the stream multiple times.
This hike is not for beginners. If you don’t have the upper body strength to use a rope to help pull yourself up a steep incline...steer clear. You’ll have to hike up the third waterfall to get to the ridge around the crater. It uses ropes almost all the way up. Those who take 6 hours have a full pack and are walking the trail slowly.
If you’re tracking your movement on All Trails you will not get lost.

no crowds!!! wonderful trail. I recommend for anyone visiting this area. take your kids but not your gramma. bring a garbage bag and collect trash as u go.

way to many people!!!

Pretty easy hike with a waterfall at the end as a reward. Went early before the lot attendant arrived, but we still had to pay upon leaving. Go early as the parking lot was full by 9am.

Beautiful and so worth it. The most crowded times is early morning/noon, later on gets a bit better. Fun for everyone, would suggest to wear safe shoes since it’s gets muddy/slippery places. For a tourists, I would suggest this waterfall as a must to visit what doesn’t take a lot of effort but are so beautiful.

This is a hard hike!! Very very muddy and slippery. Before I went (7/9/18) I read comments and thought I was prepared. But it is muddy from start to finish. While hiking around the rim I had quite a few close calls with slipping and nearly falling off the ridge. You really need to give yourself time to take it slowly. I would recommend starting this hike no later than noon. My boyfriend and I started at 11:35 am and didn’t get done until 6 pm. We are in fairly good shape, but can get turned around a few times. Sometimes the bright pink or orange markers are not very clear. Keep your eyes peeled for them, near the ground tied around a tree or within eye level. I hiked the legal way to stairway a few weeks ago and thought that was much easier than this hike. Not positive if I will be doing this hike again or recommending it, especially not to people from out of state.

Beautiful trail that opens to a grove of large pines! Muddy and rooty- of course!

Wear shoes with good traction! I wore hiking boots and my kids had water socks. Both worked fine for the slippery trail. Gorgeous hike. We started at 6pm and were the only ones there.

Good easy hike!

This is a very crowded trail is the only reason I'm giving 3 stars instead of 5. If it wasn't so crowded, I would give 5. If it has been raining, be prepared to get your shoes muddy.

Completed with a "newbie" so the trek was slow and with the recent rains some definite slick spots.

Decided to take the road back since the trail was a little slick.

Ended up being 2.5 miles.

Good easy trail for all ages. Took our 3 year old (have to carry her most of the way as she nodded off) and our 8 year old no problem.
A bit muddy when rain, especially if you go up to the trail on the left having reached the water fall. Beautiful bamboo lined trail from this part.

Definitely a cardio workout! Beautiful views up top. Wouldn't recommend beginners to do it.

One of my favorite hikes! Yes, it’s muddy and yes, it’s dangerous at times. Just be smart about the decisions you make. There are plenty of ribbons to point the way, some you may have to look harder for. But they’re there.

Amazing hike. Climbing the third waterfall was a thrill. Pretty challenging and doing it hungover didn’t help. Would recommend bringing more water than you think you need and plenty of snacks.

Nice short hike.... crowded....

Nice short hike with a great waterfall at the end. Regular workout shoes were sufficient.

Beautiful. Very slippery when it is raining so be careful.

Ridgeline, crater, and waterfall all in one hike. fun hike! just shy of 4 hours for an experienced hiker in small amount of rain. did fine in tennis shoes and didn't have to pull out the crampons. I would advise leaving plenty of time before sundown because the trail is difficult to navigate in the dark even with a light

It was such an enjoyable hike. Not hard at all and the sights along the way were amazing. It was a bit crowded but manageable. The only thing was how muddy the trail was. Not sure if it had recently rained, but some parts were kind of slippery.

LOVED this hike. However, please make sure you are prepared and have some back-up plans of the weather turns for the worst. I did this hike yesterday and got pelted with rain at the top of the crater rim. As said in many reviews before me this hike is grueling and muddy, especially in the ridge area (arguably the most dangerous portion for us). I would HIGHLY recommend buying some dirt spikes that slip over your (I hope) hiking shoes. They’re about 40 dollars depending on where you go and they could absolutely save your life and definitely save you from slipping. People have fallen off the rim of this crater and died. This hike is very dangerous, especially with wet conditions (basically always). Please do not make this your first hike on Oahu, especially if you’re not an avid hiker or are unfamiliar with the wet and muddy conditions of many Oahu hikes. Also, I’m a very active person and it took me about 5 hours to make the entire trip, crater and all. I started hiking this around 3pm and came back in the dark. So I would definitely plan accordingly. We caught up to some hikers hopelessly lost in the dark and hiked with them back to the entrance.
