Beautiful hiking trail. We went to the falls, alongside the cliffs for astounding views into the canyon that you cannot get from the lookouts. We are in average shape, early 30’s and hiked this in about 3 hours with plenty of stops for pictures along the way.

Most of this trail belongs to the Waimea Canyon Trail (from Puuhinahina lookout to Waio'po parking lot). About half of mile of this trail is on the main road in the park, Koke'e Road--potentially dangerous when visibility is low.

In addition, this trail while do-able for all ages, isn't "easy" by any means--requires crossing streams and drastic descent in elevation.

Great views. We went to the falls with lots of stops, about 3hrs. We had to reschedule a lot of activities due to flash flood warnings. Trail was muddy but for any experienced hiker totally doable in wet weather. although we only had some light rain while on trail. Do not miss the views of deep in Waimea canyon! Wether this hike or another.

Ok to stop at if you are driving by a way but not a destination. A bit of history. Is really just a stroll around some old rocks and a read about what was once at this site

Took us 7.5 hours / 6.5 miles, although we did take our time in the beginning, and we had our 2.5 year old.

I DO NOT recommend doing the forest. Until then, it was a pleasant uphill climb on green pastureland with beautiful scenery of 3 volcanoes. Moderate difficulty, with a few steep parts.

Once in the forest, though, it quickly got more difficult. Narrow, rocky, muddy trail not maintained well. We pushed forward, wanting to reach the destination / turn-around point provided by Alltrails. It got even worse, more muddy (even though it's been a relatively dry winter and no rain recently), and we lost the trail a few times. My wife even fell backward into a deep puddle and was soaked with mud. We finally got to the destination -- and there was nothing there! No lookout point, just more forest. We did enjoy sitting in the cushy moss having lunch in the shade, but it was underwhelming to say the least, especially given how hard we worked.

We tried to take the trail going down, and it veered northwest, which was ok with us, as long as we were on a trail and ideally not the one we came up on. But we eventually lost it, which meant lots of bushwacking through dense brush. Fortunately, we had my GPS to navigate back out of the forest to a hole in the fence to the pastureland, took some ladders over barbed wire fence, and all the way back down (well, actually, we were lucky to hitch a ride in the back of a pick-up for much of it).

While it was scenic and quite an adventure, I do not recommend going into the forest or spending much time there. I wish this was clearer to us.

Great hike to the small water fall...very cold in Jan. The views along the way are fantastic. Stop at the cliffs overlook on the way to the water fall. It’s about 4 miles round trip.

Very disappointing to read about all the car break ins that occur. This seems to happen at just about every hike I have read about.

The Canyon trail his great! You can reach a small waterfall in which you can swim. The back pipe trail is not really interesting except if you want to be out of the crowd.

We sooooo enjoyed the views from this Trail. Some challenging mud slides but a rope to pull you up. Thanks Waimea Canyon for showing us your beauty - Mahalo!

Well worth the pain of up and down. the Vistas at the top were spectacular and the waterfall was literally "Kool" so if you take the hike make sure you enjoy a refreshing dip to cool you down for the hike back to the road. This is one of our favorite hikes on Kauai. Thanks Mother Nature for such breathtaking views.

Feels like you’re in heaven.

Very good hike with great views and two waterfalls. Better with the Black Pipe loop than just an out and back.

Went up on a super clear morning which was nice for a view 100% of the time but somewhat scorching hot as the breeze was minimal and no shade for about 2 hours hiking up the hill. (I was training with a large backpack which slowed me down some and I suspect most people without a heavy pack on would make it up faster).

Once we made it to the tree line, my big black pooch, and I saw a boar and a few hunters. We didn't want to get caught in the middle of anything and quickly got away from the area back down the hill. So beware of that, especially if you have a dog that could be mistaken for a black boar or that gets lost on hikes chasing after pigs or their smells. I'd do this again, maybe without the dog and earlier in the day to avoid the heat. Didn't make it to a waterfall or anything other than the tree line. Great views.

The road portion is 2.5 miles from the boy scout camp. Look for a clearing on the right immediately after a bridge. This will take you to Koolau Summit and Trail. Once you reach Black Juction marked by two wooden signs, veer left if you want to go an old helipad with a view. Veer right to continue on the summit trail which will take you to Pu'u Hina in about 1.5 miles. At Pu'u Hina , you can turn around or continue to hike along the Koolau Summit. Very overgrown and muddy. If you miss the critical junction, the road will take you all the way to Kahuku. So, remember to look for the junction off the road at 2.5 miles from the camp. This is not the state maintained Kaunala trail I am talking about. The complete loop as depicted on the map is the Kaunala Loop trail. The actual Pupukea Summit Trail goes to the helipad and ends there.

Reading these reviews I think that most of the posters have this trail mixed up with the Kaunala Loop trail. Both park at the same spot, both begin on the same paved army road, but the Loop Trail is the "real" state trail. This "summit" trail is supposed to be just a long slog uphill on the old Army training area roads. Unfortunately looks like a lot of posts here are describing the Kaunala Loop Trail.

Very interesting place. Nice hike.

Neat history, certainly a bland hike for the adventurous type, but it's island identity.

Gorgeous views.

Wow just wow. All the good things in the other reviews are true!

There are more trails in this area than Alltrails is showing us. I did a larger loop that included the Kumuwela Trail, which I started by Camp Slogget. Take a snapshot of the trail map at the park lodge (or buy one) for better details. Be sure to hit up the vistas just southeast of the waterfall!

Late afternoon walk to the tree line. Got there at sunset and back to the truck just before dark. Nice views.

This hike was the last one I did during my trip to Kauai. I will say the Black Pipe portion of this trail is pretty mediocre, but the rest of it is incredible. If you're up for some exercise, this is the way you should experience Waimea Canyon. It becomes much more impressive and magical the farther you get away from the overly crowded lookouts. Also, Waipoo Falls at the end is amazing. Totally worth the effort. Check out my blog post for more on this hike!

Nice trail. Would say easy versus the moderate as shown. Nice way to spend an hour and a half or so in the sunshine.

This trail is not that bad. Pretty cool views, some good uphills too. The only problem with this map are the two spots that overlap each other. They got us pretty lost because they are not accurate. Hike down the "paved" trail until you see the second, yellow warning gate. Turn left and follow the old abandoned highway until you get to another warning fence. Just before it there will be a washed out part of the highway on the right and a steep trail up covered in red mud with another warning sign- take it. It may have a lot of debris but it clears up just over the hill. Follow that trail until you see a trail head for Kaunala trail on your left(there will be a tan tree growing out over the dropoff on your right). Follow this trail for quite some time and it will take you back to that original "paved" road. Safe travels!

Don't get me wrong - this was a great hike. However, somewhere along the way I believed there would be a great view from the top but that reward was elusive due to the low tree canopy, even though the weather was clear. The abrupt change about half way up from hiking pastureland to the moist forest bog was welcome and intriguing. The trail was muddy, however, and I found myself going knee deep in it a few times. Something better than the running shoes I was wearing would be advised. Despite being marked with flagging, it seemed easy to lose the trail, especially when searching for firm footing. Not a risk really of getting seriously lost, but if you lost the trail it could be a long and uncomfortable hike out.

Love it, so beautiful. There is actually two great spots for amazing views, but you have to find the short little off shoots for both of them that lead to clearings to see out over the valley, they are both kind of hidden. I used to Run this trail every morning when I loved in Pupukea, absolutly perfect for a nice 45 minute run, never gains or loses elevation to much. Do not let the gate and warning signs at the entrance scare you, it is accessible to the public, though during the week you might run into some military exercises on the pupukea range, and it is also a very popular hug hunting location. Like all other trail-head's on Oahu, don't park here with a rental car, you have a high chance of getting broken into. Make you car look like a North Shore car, beat up with lots of stickers, and they will leave you alone :)

Had a nice hike on this trail. Easy to follow. Very rooty and muddy in some sections. If you have kids or strollers u could just do the road part along the eastern side. CAUTION: our car was broken into at the parking site at the trailhead. Both passenger side windows were smashed and some stuff stolen.
