HikingGreat!Scramble

Good hike, mostly shaded. Gets more challenging as you approach the very end. Trail was in great shape today. No mud and I had it all to myself. I brought my pup, who is a very good little hiker, and she did not have any issues.

HikingScramble

Pretty empty! Everyone does the east ridge instead. This one is not as maintained but more relaxing and calm since it’s not crowded. The first 1/3 and last 1/3 are straight climbs with some ropes included. the entrance isn’t super obvious since there’s no trail marker, but it’s right before the white building on the right. Parking at Kouliouou is always difficult, but we lucked out with a spot on the block today. There was a cop giving out parking tickets. I found this to be much easier than most ridge hikes. There is the option to continue on and do the loop but it was SUPER windy at the top today, wasn’t worth the risk.

I was surprised by the lack of people on this trail. I think they opt for the more well known kuliouou ridge trail. The start is a steep ascent that then levels, followed by steeper ascents. There's not a view in the first 3/4 of the hike but once you get high enough, the ridge opens up and the view is spectacular. I liked it better than kuliouou.

About half way the trail gets hard to find, the pine needles on the ground make it a sloppy slope back down to the bottom. Awesome view of koko head and diamond head from the top. Not much to see on the way up.

This is a trail for experienced hikers. Steep start to the ridge. Then the path is slightly overgrown but not too bad. Some parts of the path are run down so be careful where you step. The last part of the climb is a real climb wall. About 2 times 15ft. But the ropes are in good condition and any adventurous soul would be ok. The view is worth all efforts. So enjoy!

Time: 3 and 1/2 hours Summit: No, we turned around it was raining and getting slippery. Review: This hike is a tough climb up the mountains. There a sections with ropes and it does have multiple spots that are overgrown. There are pink ribbons in place, look for those if you get lost. I would say we are moderately experienced hikers and would rank this as pretty difficult. We used tennis shoes but did turn around before the final summit which still took us 3 and 1/2 hours. However, you still see spectacular views only going this far. The other individuals on the trail that were going higher had on hiking boots and/or spikes. I would also recommend longer pants for the overgrown areas. There are a couple rope sections that are straight up - beware coming down them. Overall great hike, great workout, not overcrowded!

This should be rated as one step above moderate. Excellent hike. Need high ankle hiking boots as the overgrown tree roots and rocky road it’s an ankle breaker. Get those leg muscles ready for stair climb at the top and decent back down.

This is one of my favorite quickies. An excellent workout (1700’ elevation gain in the first .3 miles) with some unique views of Kuliouou and ‘Aina Haina. Parking: Park along the road before the trailhead in a respectful location. Residential parking manners apply. Hike: Before the trailhead, follow the paved road down and turn to the left. Just before the substation, you’ll see a trail to the right that instantly climbs into the trees. If you get a little lost in the ironwoods, just look for a slightly worn path in the needles. Pink ribbons are visible all along the way. There are plenty of ropes for the slope scrambles near the top. Difficulty: This is probably not a good hike for dogs or children. Ratings: Payoff: 9/10 Intensity: 9/10 Risk: 7/10 Wayfinding: 7/10

This is not Hahahione, but the western ridge of Kuli'ou'ou. This ridge will take you to Pu'u O Kona, one of the prominent peaks of the Ko'olaus. You can connect this ridge to the main Kuli'ou'ou to make it a loop hike. Definitely a challenging ridge hike though with some steep sections, narrow ridges, and rock climbing. The views are awesome though if you catch it on a clear day. For more on this hike, check out my blog post! https://www.thehikinghi.com/single-post/2017/05/30/Puu-O-Kona-via-Kuliouou-Ridge

6/11/2017-I think this may be the kuli'ou'ou west ridge hike (not hahaione) which was cool and involved a bit of climbing. A little muddy and slippery due to rain but the views are pretty nice. Thankfully it wasn't too sunny and there was a steady breeze on the ridge.

This is not Hahaione ridge hike by the way, I'm not sure about the pictures, but the map shows the Pu'u O Kona ridge hike, also knows as the Kuliouou west ridge, you can do a loop if you head east once at the top to the well known Kuliouou ridge trail. The Hahaione ridge hike is located in the Hahaione valley, off of Hahaione St, you can also do a loop on this one that ends at the water tank at Pukoo St. The hikes are nice but I'll give it 1 star cause of the misinformation.

Amazing hike, when you park follow the hard road to the left and right before the water building it's on the right, no marker just have to find the trail. If you're not in shape I wouldn't recommend this trail, it's straight up and once you get to the ridge it gets sketchy at times but views are worth it. I think people have taken the wrong trail in some of these reviews because there's no way you can get lost once on the trail. Watch for wind almost got blown off the ridge at one point.

I went up the hunting trail to the right. Great hike. About 4.5 miles round trip. Only negatives is there is more litter on this trail than I've seen on all the other trails I've done.

It is amazing!!!!!! I would use his app when hiking though because towards the beginning you can get lost at a couple points. Bring water and gaterade and more water and gaterade. The scene is worth going all the way up but be careful because it is slippery with mud in some parts. If you're older or have knee problems I advice not to go the entire way (can easily lose balance and fall). Make sure you bring enough food too, it is a workout. It took us about 3.5-4hrs because it is a constant slight uphill.

One area by the peak is very steep and slippery if it rained recently.

First to Review

We started at Hahaione and hiked over to Kuliouou. Beautiful and shady. When we got closer to Kuliouou trail we had to hike down side of mountain and it was steep, but doable since it hasn't rained much lately. Would be too slippery in wet conditions. Loved the whole journey. Didn't see any other hikers until very end.
