Three Peaks, One Question: How Far Should You Go on Mount Olomana?
The first time I attempted Mount Olomana, my friend took us via a lesser-known route used by first responders to rescue and recover bodies from the fall zone. Let that sink in for a second.
You pop out between Peaks 1 and 2, which kinda felt like cheating and also like a preview of exactly what this mountain is capable of.
Mount Olomana, better known as Three Peaks, is arguably the deadliest hike on O’ahu and the most talked-about trail after the Haiku Stairs. It lives up to its expectation and can be very dangerous.
Nonetheless, I wanted the full experience. All three peaks, the right way, with someone who knew what they were doing. A few months later I met that person! She’s climbed Three Peaks multiple times and loves taking first-timers all the way to Ahiki.
The night before, I barely slept. Overthinking whether summiting Peak 3 was the right call or just reckless. I decided I’d trust my gut once I got there. No shame in turning around. That’s not failure, that’s good judgment.
So does Three Peaks belong on your bucket list? I’ll give you my honest take and let you decide, not based on a highlight reel, but on what it actually feels like to be there.

Where to Park for Mount Olomana?
Parking for Three Peaks is almost as frustrating as the hike itself. Almost.
There is no designated parking at the trailhead. You’ll need to park along Auloa Road, about 0.8 miles from the actual trail, just off the Pali Highway. Straightforward enough until you see the sign.
“No Parking on Footpath.” Simple, right? Except nobody tells you that the “footpath” is an uneven, barely-visible patch of asphalt that the County of Honolulu has decided counts as a sidewalk. I parked behind the white line, thought I was fine, and came back to a $35 ticket. Nearly every other car had one too.
Here’s what you actually need to know: all four tires need to be completely off the asphalt and on the dirt. Stay as far right as possible. If any part of your tire is touching that patch of asphalt, you’re getting a ticket.
I hope the County of Honolulu takes that ticket money and paints a line. One line. That’s all I’m asking.
One more thing: this area is known for car break-ins. Do not leave valuables in the car.
Hiking Three Peaks on Mount Olomana Trail
The Warm-Up
Before you even set foot on the trail, there’s a 0.8-mile walk along Loop Road. On the way in, it’s a pleasant warm-up — palm-lined, lush, and quiet in the early morning. On the way back, after 4+ hours on the mountain, it’s a different story.
You’ll pass the Royal Hawaiian Golf Club entrance and a guard station. Don’t overthink it, just keep walking. The guard is there to track hiker traffic, not stop you.
The Hike Begins
The trailhead is on the left side of Loop Road, marked by a brown sign listing six fatalities. It’s a good reminder that this hike is not to be taken lightly and to prevent you from becoming another statistic.
The Honolulu Fire Department responds to dozens of emergencies on Olomana every year, many requiring helicopter rescues and airlifts. Know your limits and come prepared.
The hike starts in a shaded forest. Watch your footing from the very beginning. The mud and slippery roots are unforgiving, and the low-hanging branches will find your forehead if you’re not paying attention. Ask me how I know.
The trail has recently been upgraded with new signs, which is genuinely helpful on the return trip when your brain is fried and your legs are done.
From here, it’s a relentless climb to the first peak, known as Olomana. You gain more than 1,500 feet of elevation in just one mile. By the time we reached the summit I was dripping sweat and I hike ridges regularly. Just so you know what you’re signing up for.
Before you get there, you’ll hit your first real test: a rope-assisted rock wall climb near the top. Further up (not pictured), there’s a second separate scramble over boulders — though there’s an alternate footpath around it that’s a bit easier. We took it. No regrets.
Peak 1: Olomana — Best Views on the Trail
It took us about an hour and a half to reach the first and highest peak. The views are worth every sweaty step.
This is arguably the best viewpoint on the entire hike. You get 360 degrees of everything: Kailua, Lanikai Beach, Waimānalo, the Koʻolau Mountains, the windward coast, and Kāneʻohe Bay stretching out below you. This panorama makes you forget you were just white-knuckling a rope climb five minutes ago.
From here, you also get your first real look at what’s ahead — Peak 2 and Peak 3 sitting right in front of you. If Peak 3 looks intimidating from this angle, that’s because it is.
This is where most people stop, and honestly, turning around here is the smartest choice. The views from Peak 1 are the best on the trail. If you came for the scenery, you’ve already won.
Peak 2: Pākuʻi – The Middle Child
Pakuʻi is almost the same height as Peak 1 and only ~11 minutes away. But don’t let the short distance fool you. The section between the two peaks has seen at least one recorded fatality, in 2015.
You traverse a narrow and exposed ridge, with ropes to assist you and drop-offs that will get your attention. If you’re not comfortable with heights, this section may not be for you.
Looking back at Peak 1 from here is stunning and humbling. The people standing on the Olomana summit look like tiny ants.
From this angle, Peak 3 looks significantly more intimidating than it did just a few minutes ago.
Take it all in and make your call. Most fatalities on Mount Olomana happen between Peaks 2 and 3. It gets very technical from here and the stakes are high. No room for error whatsoever. There is absolutely no shame in turning around. In fact, it’s the wisest choice.
Descending Peak 2
If you decided to continue, the descent toward Ahiki starts immediately — and it is steep. Like, genuinely terrifying steep. You are fully relying on the rope, and the thoughts start creeping in whether you want them to or not. What if it snaps? What if I lose my footing? This ridge is not forgiving. One wrong move and you’re not walking away from it.
The rope on this section was recently replaced, which helps but you’re still putting a lot of faith in the ropes, the rocks, and yourself.
Peak 3: Ahiki – The Deadliest One
After the descent, you begin Class 4 scrambling. If you’ve done any rock climbing you’ll recognize the exposure immediately. I’ve climbed before and I’m no expert, but I could hold my own. Even still, I was fully aware of what a broken hold or a snapped rope would mean out here. Never attempt this in rain or questionable weather. Ever.
The most interesting feature up here is the keyhole rock formation. You don’t have to climb through it, but you can stop for a photo. Getting into it was honestly the hardest part of the whole section for me.
It took us about 45 minutes from Peak 2 to reach the Ahiki summit. And honestly? The view is a little anticlimactic. You’ve already seen the windward coast from Peak 1.
From Ahiki, you get Peaks 1 and 2 in the background. They look like a tooth from this angle. But the summit itself isn’t the payoff you might be expecting. You see what I mean when I say the best views are from the first or second peaks?
The Descent — Harder Than You Think
Let’s not forget the descent. Going down is harder than going up. Full stop. By the time you’re heading back, your legs are already done, it’s getting hotter, and every exposed section looks steeper than it did on the way up.
Slow down and take it one move at a time. This is not the place to hurry. It took us just under an hour to make our way back to the first peak.
Is Peak 3 Worth It?
Honestly? That depends.
It was worth it for me. But I came in with experience — rope climbs, rock scrambling, exposure — and I still had moments where the weight of what I was doing was very clear. This is not a hike where you push through discomfort and figure it out. The consequences of a mistake between Peaks 2 and 3 are not a twisted ankle. They are fatal. That sign at the trailhead exists for a reason.
If you are fully comfortable with exposure, have experience with O’ahu ridges, technical scrambling and rope climbs, and are not afraid of heights — and I mean genuinely not afraid, not “I’ll be fine once I’m up there,” then Peak 3 might be for you.
But here’s the thing: Peak 1 gives you the best views on the entire hike. Peak 2 gives you a perspective that few people get to see. Both are incredible accomplishments that don’t require you to bet your life on a rope and a rock hold. There are plenty of challenging, rewarding hikes on O’ahu that will push your limits without it being a matter of life or death.
Hike at your own risk. Know yourself. Check the weather. And whatever peak you turn around at, own it.
How Hard is Olomana?
Pretty darn hard. It took us 4 hours and 45 minutes to complete the hike and we barely stopped.
Peak 1 is hard. It’s steep, relentless, and will humble you regardless of your fitness level. But it’s doable for a motivated intermediate hiker who respects the terrain.
Peak 2 adds roughly 30 minutes and a more rope sections, exposed descents, and your first real taste of what this mountain is capable of.
Peak 3 is a different category entirely. Technical, fully exposed, and for experienced hikers only. Not experienced as in “I hike regularly.” Experienced as in comfortable with Class 4 scrambling, rope climbs, and genuine exposure where a mistake is a matter of life and death.
Rain changes everything. The rocks become slick, the trail turns to mud, and sections that are manageable in dry conditions become genuinely dangerous. Do not attempt this hike if it has rained recently or if there’s any chance of weather rolling in.

Nearby Hikes
Lanipo Ridge
- Distance: 6.7 miles
- Elevation Gain: 3,475 ft
- Difficulty: Hard
One of the longer, more demanding ridges in the Ko’olau range. From the summit, you’re looking right down at Olomana standing on its own. Lanipo is a sustained grind with overgrown sections, narrow ridge terrain, and a false summit that tricks most people into thinking they’re done. Spoiler: they’re not.
Kaʻau Crater
- Distance: 5.6 miles
- Elevation Gain: ~2,000 ft
- Difficulty: Hard
Three waterfalls, a prehistoric-looking crater, and a ridge climb that hits you all at once. Kaʻau is one of the most diverse hikes on O’ahu and one of the few where you can spot Olomana off in the distance from the summit.
Wiliwilinui Ridge
- Distance: 4.76 miles
- Elevation Gain: 1,805 ft
- Time: ~3 hours
- Difficulty: Moderate
If you’re eyeing Olomana but not quite sure you’re ready, Wiliwilinui is a good place to start. It’s an easier hike than Peak 1 alone — well-maintained, with stairs and a few rope sections on the steeper upper climb, but without the exposure or technical scrambling that Olomana demands. A solid introduction to Ko’olau ridge hiking.
