A more direct approach to the Koolaus and Olympus ( Awa'awa'loa). Kolowalu is a finger ridge that connects to Wa'ahila Ridge. You gain elevation very quickly, and is quite demanding and a good cardio workout, even for a veteran hiker. A finger ridge trail that can be very mudd yand slippery. 95 percent uphill. Elevation gain 1400 feet in less than a mile. Trail ends at the junction with Wa'ahila Ridge. Continue on Wa'ahile ridge to the Koolau summit.

All I can say is that the struggle the entire way was absolutely worth it. Once you hit the ridge, it’s gorgeous views the entire way. I would absolutely check the weather beforehand and also recent reviews to see what the status of the trail is because it does get pretty narrow and there can be a fair amount of mud. Regardless, so worth it! I’d do it again, of course, after my legs recover.

Strong body hike in the beginning, like Koko Head on steroids...gets easier when you get to the end and head up to Olympus but there are some gnarly ropes. Really solid 4-5 hour activity

Hiked to slightly past the halfway point. A challenging, rugged trail with some tricky terrain problems and a ton of mud. Great workout.

Some nice views in places, otherwise you're in the thick of the trees. Pretty humid; rainforest hiking!

A little challenging at some places, but the efforts are rewarded with the nice views. The beginnng of the trail isn't so beautiful, but once you hit the ridge, you get some nice lookouts along the way. However, if you want your trip to worth it, make sure to looked at the weather before. It rainned the day before I did it, and the trail was slippery and muddy. At some point, we had to use the ropes, so if ou attempt it on a rainny day, prepare yourself to get your hands and your shoes dirty! I'd recommend to wear long pants as well, cause, I would say the last third of the trail isn't so well maintened and is really bushy.

I loved this hike. We done it Friday morning and it was great. a little slippery in spots but not too bad. I went to the ropes my partner wasn't with it. haha

Wasn’t as hard as I thought it was going to be BUT the views were very rewarding! Love this trail and would recommend it to both novice and seasoned hikers.

Awesome! Difficult in places and worth the work when you see the view at the summit of Olympus.

Great hike!! Don't underestimate the ones who say tough incline! we didn't make it to the rope part, as we had a time limit. The passer-goers said we had made it a bit more than half way. Still very much worth it. Beautiful vantage points! Slightly muddy, but not a "ruin your shoes" type.

This hike offers a beautiful view. When I hike in Hawaii I bring micro spikes with me. Bring one on this hike as well because it will help you. It can be extremely muddy all year round. Oh... do bring gloves and have extra bags and towels at your vehicles to store your dirty shoes and wipe yourself down. You probably be muddy.

Harder than I thought...especially when you’re not comfortable using ropes in muddy areas.

Our route:
We staged a car at Wa'ahila state park at 7am, and drove the 10-15min to Pu'u Pia/Kolowalu trailhead. Hiked up to Mount Olympus then down Wa'ahila trail back to the park. 5.5mi, 2600ft elev, and 5hrs total, that's with multiple longer breaks as well.

The ascent is relentless, but it's really not that bad if you're in shape and the conditions aren't wet. Liken it to 3x Koko Head maybe? Very strenuous for most, but doable. No scary parts or death drops, sorry thrill seekers. But there are some stunning views, and if you're lucky enough to have a clear day at the summit, you'll want to hangout for a while!

challeging hike .
Really exausting the first hour then when u Turn left to mount olympus its all about ropes and some steep ways. The views are great along the way. Make sure u bring hiking shoes otherwise it gets really dangerous. Bring at least 2 bottle of water and some food.

One of the more challenging hikes I’ve been on, it’s almost all uphill and pretty steep at parts. Got rained on a couple times on the ridge so I would recommend checking to weather and bringing a light jacket for cover as it did get a little chilly in the rain with all the wind. Hiking up through the clouds was quite the experience, albeit exhausting. A good amount of rope sections here, and I would advise wearing gloves if you have them as some of the ropes are pretty rough on non callused hands. The actual peak itself is not in an open area, so the views from there are difficult to find, but the false summit just below has very rewarding views when the clouds finally parted. Only giving it 4 stars for the large sections that are badly eroded and a little more difficult to maneuver (more ropes in these areas could help).

Super fun and not to hard, definitely my favorite hike and the view is definitely worth it, the only hard part is the beginning which is straight up hill and the end which is another intense climb with ropes, but you can definitely feel the mana when your up there

First mile is a killer cardio workout. Always love doing Mt Olympus, but this the first time taking the Kolowalu to get to the main trail...great hike to do before having to go into work this afternoon.

Absolutely loved the views from the summit! Can see all over the island. Not sure why this hike doesn't get more hype.

Great hike. Not too hard but no too easy either. A nice way to spend half a day. there are great views along the way and at the top on a clear sunny day. try to do this hike when the trail is dry, otherwise it would be pretty treacherous when wet.

There aren't many places where you can drive 20 minutes from a city downtown to a trailhead and be immediately in wilderness. What an amazing hike. The first mile is not fun but so worth it. It was a beautiful day, and the views at the summit were unbelievable. The highlight of my visit!

Awesome hike, might be my new favorite! The first mile or so is steep, then it evens out until you climb ropes at the summit. Would not be a good idea at all in the rain so check the weather. Did not find it to be sketchy and trails were marked with actual signs, nice! Entrance is down Alani St. It happened to be very clear when we got to the top for amazing views of Honolulu, Pearl Harbor, Kailua, Kaneohe Bay and the Kaau Crater. Must do!
Oh also not dog friendly unless you do a shortened version.

Fun and tough hike. It's pretty much a long and continuous uphill until you finally summit. This peak is a cloud magnet though, so you need to get lucky for optimal views. I went on a cloudy day and still thought the views were fantastic. You can see so much from up there such as Honolulu, Diamond Head, Three Peaks, Chinaman's Hat and a ton of the Ko'olau Range. For more info check out my blog post!

Nice hike to the top on a clear day.

One of my most memorable experiences on Oahu

If you're coming from Manoa the first mile or mile and half is all incline but after that is super easy. There are some few ropes on some parts of the trail. We went when it was super cloudy, but decided to stay at the top a bit longer and it eventually cleared up. You can overlook Kaneohe, Kailua, Waimanalo, Diamond Head, the airport runway and of course Ka'au Crater. There are 2 falls summit. Other than the super crazy incline in the beginning this hike is super awesome! Would do it again.

definitely a good cardio workout. this peak is most often times cloudy, make sure to go on a clear day to catch the beautiful views.

Not a technical hike but definitely steady uphill, narrow path at some places which will slow you down. Make sure you bring enough water and mosquito repellent

Great trail! It is a little muddy and be prepared to do some light climbing. Several spots to enjoy the view and take some really nice pictures of Honolulu.
