Are you searching for a list of the best hikes on Oahu, Hawaii? Well, you’ve found it! This guide from a Hawaii local has everything you need to know about the most amazing hikes on Oahu.
Hiking is one of the best (yet underrated) outdoor activities to do on Oahu. The hikes on Oahu are easily some of the most stunning in the world. From picture-perfect views to stunning waterfalls, Oahu’s hikes have got it all. Here are 15 of the best hikes on Oahu.
What Should I Bring to Do the Best Hikes on Oahu?
It’s important to be prepared for the hikes on Oahu. While they are varying levels of difficulty, being prepared is always important for both enjoyment and safety!
Bug repellent is highly recommended for hikes on Oahu. Sometimes I get lazy and don’t use bug repellent and I end up with bites on my arms and legs that don’t go away for a month!
Bug repellent is especially relevant for waterfall hikes, because the mosquitos are drawn to the little patches of still water. There are both traditional and natural options to help you ward off the little critters.
Your shoes will never fully recover from the dust, dirt, and mud on some of these hikes. Sometimes they simply will not make it out. (I once was on an Oahu waterfall hike and the literal soles of both of my shoes came off in the mud!)
That said, intense, professional hiking boots are not necessary for the vast majority of hikes on Oahu. Recently, I’ve been putting my Fila Women’s Day Hiker Shoes to good use, and they’ve held up quite well. And there’s also a men’s version.
Plastic Bag (Or Washable, Reusable Bag)
Most people forget to bring a plastic bag along with them on hikes to put their muddy or dusty athletic shoes in after hiking. If you’re trying to be more eco-friendly, try this reusable plastic bag and give it a good wash when you get back to where you’re staying.
Flip-Flops (A.K.A. Slippers in Hawaii)
You’ll need something to wear after you shove your muddy or dusty athletic shoes into that plastic bag or reusable bag.
If you want to support a fabulous local Hawaii business, you can buy a pair of Olukai slippers for your adventure.
It’s a necessity for hiking. Bring a little more water than you think you’ll need for your Oahu hike. Perhaps in a nice reusable bottle to help the environment out.
You want to capture all of your adventures, don’t you? I’ve been looking to purchase the Nikon D3500 to do the job.
How Can I Get to the Best Hikes on Oahu?
To get to the vast majority of the hikes on Oahu, you’ll need a car. While there are a few exceptions of hikes that can be reached by public bus, like Ehukai Pillbox and Koko Head Crater trail, these are the minority. Basically, if you plan on doing a lot of hiking during your trip to Oahu, it would be a good idea to rent a car.
Hiking Safety for the Best Hikes on Oahu, Hawaii
This section isn’t to scare you. It’s just to make sure that you’re prepared!
On most of the Oahu hikes listed below, the trails are pretty clear. However, there are a couple with slightly confusing paths, which is not ideal. So keep your eyes out for trail markers!
Trail markers on Oahu, Hawaii are typically brightly colored (usually orange, pink, or blue) flags tied around tree branches. If the trail has recently changed (which happens on occasion), the trail markers may instead be carved into trees or marked with little splashes of spray paint.
If you’re planning on doing one of Oahu’s waterfall hikes, you should be aware of a bacteria called leptospirosis that is present in the water. Leptospirosis can only be harmful if it enters the body through an open cut (so if it’s scabbed over, you’re fine) or by drinking it.
While some cases of leptospirosis may have bad flu-like symptoms, others have no symptoms at all. Personally, I have not heard of anyone actually getting leptospirosis on these hikes. Once I even got a small cut from a rock in a waterfall pool and did not have any signs of leptospirosis.
If you would like to read a bit more on the bacteria, here’s a page from the CDC.
My Ranking System for the Best Hikes on Oahu, Hawaii
I decided to rank these hikes on Oahu based on three different categories: effort, reward, and number of people. These categories will be ranked on scale of 1 to 5, with 5 being the most. So for me, ideally, the numbers would be 1 for effort, 5 for reward, and 1 for number of people.
The Effort Scale
For the effort scale, these were the thoughts going through my head as I did the hike:
- 1: I took a three-year-old on this Oahu hike, and he did it without being carried.
- 2: Ok, this Oahu hike is a little bit difficult, but it’s still fun.
- 3: This hike is quite difficult, but definitely still doable with several breaks.
- 4: Why the heck did I subject myself to this? Should I turn around? No, I’m too stubborn for that.
- 5: The only reason I’m doing this brutal Oahu hike is because it’s at the top of my bucket list. This is the hardest thing I’ve done in my life.
The Reward Scale
For the reward scale, these were the thoughts going through my head as I saw the end of the hike:
- 1: It’s not on this list, because a hike on Oahu with a level 1 reward is not worth it.
- 2: It’s also not on this list, because a hike on Oahu with a level 2 reward is not worth it either.
- 3: I mean, it’s a good Oahu hike. But I also feel like I’ve seen better for significantly less effort.
- 4: This is an awesome Oahu hike. That effort was totally worth it.
- 5: This is probably in the top 10 views I’ve ever seen in my life.
And well, the number of people scale is just relative to the hike with the most people I’ve ever seen (a.k.a. Diamond Head, which was much too crowded and did not make it onto this list).
Ok, I’m All Set! Tell Me About The Best Hikes on Oahu!
Number of People: 4/5
Lanikai Pillbox is one of my favorite hikes on Oahu. It’s relatively easy, and you get an amazing view of the Mokulua Islands and the Pacific Ocean as a reward. You can make it to the first World War II military pillbox in 25 minutes! (And honestly you don’t need to go any further.)
The one downside to this hike is the number of people that come on it. The combination of fame, views, and ease cause Lanikai Pillbox to be rather crowded – even at sunrise. That said, I’d still say that this is one of the must-do hikes on Oahu.
There is only street parking available for the Lanikai Pillbox hike. Watch out for no parking zones, and please do not block the residents’ driveways!
In case the difficult Oahu hikes aren’t what you’re looking for, I also have a guide to the best easy hikes on Oahu.
Koko Head Crater Trail
Number of People: 4/5
Koko Head Crater Trail is another one of the well-known Oahu hikes. That said, I think it’s overrated. It’s not a bad hike, it’s just an overhyped one.
If you’ve got a limited amount of time on Oahu, I don’t think Koko Head’s effort-to-reward ratio is worth it. It’s a lot of effort on a mile-long, very steep, rickety old 1,000-step train track for an okay view that’s usually a little cloudy from fog or smog or vog (volcano-induced fog/smog). And then you get to the top and there are a ton of other exhausted humans up there with you. While some people can do this hike in 20 minutes, it takes me around an hour.
I will say that you can see a decent chunk of the island from the top of the Koko Crater Hike. You can see pretty much the entire southeastern section of the island. It’s just not the most visually stunning parts of the island in my opinion. Maybe it’s more awe-striking at sunrise – or you can try one of these other sunrise hikes instead.
There is a designated parking lot for the Koko Head Crater Trail.
Lulumahu Falls – ILLEGAL
Number of People: 3/5
Lulumahu Falls is one of the easiest and most rewarding waterfall hikes on Oahu. For about 45 minutes of hiking with a couple of easy river crossings, you can see a thirty-foot waterfall! That’s pretty amazing to me. Just as a note, the pool at Lulumahu Falls is not quite deep enough to swim in.
If you happened to complete the hike to Lulumahu Falls in the past (2017 or earlier), the path has changed since then. Because it is on the Hawaii Board of Water Supply property, they have implemented some measures to deter hikers (a.k.a a few metal fences).
Some hikers have simply chosen to hop the fences, but there is an alternative path that does not require fence-hopping. Instead of immediately turning left according to the old path, continue to go straight for a bit. Once the path naturally veers to the right, keep your eye out for a path on the left. Take that path and you’ll be on your way to Lulumahu Falls!
There is a muddy parking area for Lulumahu Falls just off the side of Pali Highway.

Tom Tom Trail – ILLEGAL
Number of People: 1/5
Right next to the famed Makapuu Lighthouse Trail is the Tom Tom Trail. As a matter of fact, you use the same parking lot! The entire Tom Tom Trail is six miles long, but most people stop within the first couple of miles of the hike anyways (that’s where the stunning views are).
This also means that the time necessary to complete the hike varies a lot – from only an hour to 4.5 hours. Just a heads up, the first small chunk of the hike is rather difficult, but don’t let that stop you! It will get easier as you go on!
*Note: People have reported getting hefty fines just before starting the Tom Tom Trail hike, since the hike is illegal.
Number of People: 1/5 (Honestly it should be zero out of five, because we didn’t see anyone else as we were hiking on the tiny island.)
Chinaman’s Hat has also made it onto this list of fantastic hikes on Oahu, because this hike is so unique. In order to even get to the start of the hike, you have to do a 30 to 45-minute kayak or paddle board trip over to the island. You get your blood pumping before you even get to the start of the hike!
The short 20-minute hike on Chinaman’s Hat is grueling. If you thought your blood was pumping from kayaking or paddle boarding, trekking your way through the thin dirt paths and miniature rock-climbing sections will make you forget about the paddling you did to get to the island.
Depending on where you choose to start your paddle, parking will either be on the side of the road or in the parking lot of Kualoa Regional Park.

Maili Pillbox, also known as the pink pillbox hike, is one of the only hiking trails in West Oahu – and it also happens to be one of my favorite hikes on Oahu.
The trail is clear once you find the start (between the 10th and 11th light poles of Kauakama Road – there’s a clear break in the grass). Other hikers are a rarity. Plus, the pretty awesome view is one that you can’t see from anywhere else. As a matter of fact, this Maili Pillbox hike is the ONLY place I can think of where you can get a bird’s eye view of the West Oahu coastline.
On top of that, this fantastic Oahu hike has four World War II military pillboxes at the top, one of which is bright pink and filled with memories of breast cancer survivors. No wonder it’s one of the best hikes on Oahu, Hawaii!
This hike is one mile one-way (two miles round trip), and it takes about an hour and a half at a leisurely pace.
Parking for Maili Pillbox is just on the side of the Kaukama road near the start of the hike.
*Note: The west side of Oahu is very hot. Bring some extra water with you.
Number of People: 2/5
Looking for North Shore hikes on Oahu? Ehukai Pillbox is a fantastic option for you. This hour-long hike is not too difficult, and it’s the only hike that gives you a bird’s eye view of the giant waves at Banzai Pipeline. And, as the name implies, you’ll reach a cement pillbox that was once used by the military as a lookout point during World War 2. (This pillbox is decked out in peace-themed graffiti.)
One note to make is that Ehukai Pillbox surprisingly muddy for a non-waterfall hike, which means there are also mosquitos in the area.
There are a few parking stalls near the start of the Ehukai Pillbox Trail.
Puu Maelieli Trail – ILLEGAL
Number of People: 1/5
Puu Maelieli Trail is the last of the pillbox hikes on this list of the best Oahu hikes. Located in Kaneohe, this hike is just off of Kahekili Highway.
To find the start of the hike, walk away from the Temple Valley Shopping Center on the right side of Kahekili Highway. There should be a bright yellow-tipped pole to signal the start of the trail. This 1.5-mile hike ends with a stunning view of Kaneohe Bay from the SECOND pillbox. (The first pillbox is right before the second pillbox, but it’s mostly underground, so no cool views there.)
As you take in the sights from the second pillbox at the end of the Puu Maelieli Trail, you’ll be in awe. In addition to the beautiful turquoise waters of Kaneohe Bay, you’ll also get to see the many sunken islands in the bay (the lighter white splotches). Sometimes, these will rise above the surface of the water and create little islands. And if you look to the north (or to your left), you’ll also be able to see the gorgeous Koolau Mountain Range and Chinaman’s Hat.
Parking is available in the Temple Valley Shopping Center or on the side of Kahekili Highway.
Number of People: 3/5
Kaena Point is slightly better than average on all aspects of judging. Despite that fact, it has still made it onto this list for a couple of reasons.
First of all, you can’t get to Kaena Point without hiking. This is actually the only portion of the coast of Oahu that doesn’t have a road. So if you want to see the scenery found on this part of the island, you have to get your legs moving and your blood pumping.
Second, Kaena Point can be done from both the west side of Oahu (Waianae) and the North Shore (Waialua) – and both of those sections of Oahu don’t have a ton of hikes. So if you’re hanging out in Ko Olina or Haleiwa and want to do a hike, Kaena Point is the hike for you.
Hiking Kaena Point from Waianae is a pretty flat trail. However, it is also 5.6 miles with very little shade. From the North Shore, the hike is about 3.5 miles – also with minimal shade. The North Shore path is quite a bit rockier than the Waianae path.
Either way that you choose to tackle Kaena Point, you’ll end up at, well, Kaena Point. The point itself is actually a bird sanctuary. It’s pretty common to see monk seals chilling on the rocks in the sun right next to the crashing waves. Please be sure to give the monk seals their space. You wouldn’t like people getting all up in your face to take pictures when you’re sleeping, so the monk seals don’t like it either.
There are little unofficial parking lots at the start of each end of the Kaena Point hike.
Likeke Falls – ILLEGAL
Number of People: 2/5 (although this very much depends on your luck that day – people like to do this hike in very large groups)
Looking for one of the easiest waterfall hikes on Oahu? Likeke Falls is the hike for you! It’s so easy that on quite a few of my times hiking this trail, I’ve seen mommy and me groups also doing it! Another cool fun fact about the Likeke Falls trail is the fact that the part that looks like a lava rock pathway was actually used by Hawaiian royalty in the past! So you’ll literally be walking where royals used to walk!
There are a couple of unexpected turns on this hike, so, if you’re thinking about doing it, refer to this more detailed most on Likeke Falls!
The unofficial parking for Likeke Falls is located at the back corner of the parking lot for Koolau Ballrooms. Please stick to that back corner of the parking lot, so the people who are actually using the Koolau Ballrooms venue have the most accessible parking.
Crouching Lion Hike – ILLEGAL
Number of People: 3/5
Recently, Instagram has been responsible for the increasing number of people attempting the Crouching Lion Hike on Oahu. This 1.5-mile and 45-minute hike is rather steep at times, but it ends in an amazing view of Kahana Bay and the Koolau Mountain range. As a matter of fact, the Crouching Lion Hike trail is so steep that it is one of the only hikes on Oahu where a pair of real hiking boots (rather than athletic shoes) might be a good idea.
As for parking, do NOT park along Trout Farm Road, as your car could get towed. Instead, park at Swanzy Beach Park.
*Pro Tip: Do not hike on or after a rainy day. That’ll just make the journey much more difficult than it needs to be.
Hamama Falls – ILLEGAL
Number of People: 1/5
Hamama Falls is one of the best hikes in Honolulu. It’s just to the east of the main Honolulu city area in a town called Hawaii Kai. Hamama Falls is a fun Oahu hike to try. It’s enough effort to get your blood pumping but not too much. There are actually a few swimming holes along the way, so keep your eyes peeled!
One of the best perks of Hamama Falls is the fact that no really one knows about it, yet the trail is extra clear. So you’ll get the falls all to yourself, and you won’t get lost!
Only street parking is available for Hamama Falls. Please be respectful of the residents and make sure that you do not block their driveways!
Pali Notches – ILLEGAL
Number of People: 2/5
This 0.8-mile hike is one of the most dangerous hikes on Oahu, especially for people that are not experienced hikers and/or rock climbers. So please if you are not confident in your hiking abilities, think again about attempting this hike!
Throughout the Pali Notches trail, you’ll be following a thin path at the top of a mountain ridge line with steep drop offs. If the island trade winds are blowing that day, that’ll make this ridge hike even more difficult. On some of the more difficult climbing parts of the hike, there are ropes to help you on your way. But be sure to give the ropes a good tug to make sure it can hold your weight! Put simply, please be safe and use good judgment while hiking Pali Notches.
If you do consider yourself to be a very experienced hiker, you can enjoy some breathtaking views of Oahu’s beautiful mountains on this hike.
The start of the hike and the parking are actually at the Pali Lookout, a popular tourist spot.
Number of People: 2/5
I’m not going to lie to you. Despite the fact that the beginning of this Oahu hike is rather flat, the journey to Waimano Falls is pretty difficult, especially if it has rained recently. I mean, there’s even a large section of the hike called “heart attack hill”!
But the reward is awesome. First of all, there is a stunning waterfall that’s about 25 feet tall. Second, there’s a pool deep enough to jump or swing into. I can’t think of another waterfall hike on Oahu with a consistent swinging rope. So if you want to feel like Tarzan, this is the hike to go on.
That said, there is one very crucial turn to take to get to Waimano Falls. If you don’t take it, you’ll get very lost. There will be a point in the trail with a clear fork in the road. (However, it’s not the one that says, “Manana Falls to the left, and Waimano Falls to the right.” It’s quite a bit after that.). Both paths will seem well-trodden. You MUST go to the left, not the right. If you find yourself in a little clearing, you’ve wandered off of the path and you should backtrack. (I’ve heard that they’ve recently added a sign at this turn, so people don’t get confused.)
Only street parking is available for Waimano Falls. Please be considerate of the residents in the area.
*Local Tip: If you do the hike to Waimano Falls in the summer, there’s a good chance that you’ll be able to snack on some wild strawberry guava as you hike. This little red spheres are only about an inch wide, but they’re full of flavor!
Stairway to Heaven – ILLEGAL
Reward: 5/5 (especially on a clear day)
Number of People: 2/5
Undoubtedly the most famous Hawaii hike is the Stairway to Heaven, also known as Haiku Stairs. This 4,000-step hike up the Koolau Mountain Range and into the clouds is one of the most popular Oahu bucket list items. However, it is also the most illegal. With a guard posted in front of the entrance and the threat of a hefty $1,500 fine, the Stairway to Heaven has only become slightly less popular.
*Pro Tip: If you just want a glimpse of the Stairway to Heaven, you can actually see it as you’re driving on H-3! To get on H-3, set you GPS from Kailua to Aiea (or vice versa). Then, as you’re driving on the side further from the ocean (we call that “mauka”), keep your eyes glued to the mountains on your side (unless you’re driving of course! Stay safe!). Between the two tunnels (right before the second tunnel), you’ll see a little silver sliver climbing up the Koolau Mountains. That’s the Stairway to Heaven.
For more information on how to navigate the steps, guard, and fine, this guide should help you out.
As of September 2021, the State of Hawaii has decided to remove the Stairway to Heaven steps. While there is no official removal date, rumors say it could be removed as early as the summer of 2022.

While I try my best to update this list whenever I become aware of a change, please check to see if these trails are still legally open before you do them. The statuses of hikes on Oahu do change, so any of these trails could become illegal, either temporarily or permanently, at any time.
