7 Best Hikes in Hawaii for Every Adventurer
Hawaii is a hiker’s paradise. It offers trails for every skill level, from beginner-friendly paths to advanced treks that challenge even the most seasoned adventurers. Here are my 7 favourite trails in Hawaii.
1. Kalalau Trail (Kauai)
- Distance: 11 miles (18 km) one way
- Duration: 2 days (full hike) or 4–6 hours (to Hanakapi’ai Falls and back)
- Best for: Experienced hikers seeking epic coastal views and a serious challenge
The Kalalau Trail on Kauai’s Nā Pali Coast is hands down one of the best hikes in Hawaii I’ve ever tackled.
It starts at Ke’e Beach and winds along cliffs with sweeping views of the ocean, lush valleys, and dramatic peaks. The full trail leads to the secluded Kalalau Beach, but even just hiking to Hanakapi’ai Falls (about 8 miles or 13 km round trip) feels like an epic adventure.
Before you go, there are a few things you need to know. Trust me, these tips will save you some trouble.
First off, if you’re planning to hike beyond Hanakapi’ai Valley, you’ll need a camping permit. They’re tough to snag, so book well in advance.
The trail itself can get slippery after rain (which happens often here), so good hiking boots with a solid grip are a must.
And be ready for water crossings. Streams can rise quickly after a downpour, so check conditions beforehand.
I always carry plenty of water, energy snacks, sunscreen, and bug spray because there’s no access to potable water or supplies on the trail.
Oh, and starting early is key. Not just to beat the crowds but also to ensure you’ve got daylight for the return journey.
Even if you stop at Hanakapi’ai Falls, you won’t regret it.
I still remember standing there, soaked in the mist, completely mesmerised by the 300-foot cascade. Moments like that are why this hiking trail in Hawaii is worth every ounce of effort.

2. Diamond Head Summit Trail (Oahu)
- Distance: 1.6 miles (2.6 km) round trip
- Duration: 1.5–2 hours
- Best for: Beginner to intermediate hikers who want iconic views with minimal effort
The Diamond Head Summit Trail is one of Oahu’s most popular hikes, and it’s easy to see why.
This short but steep trail takes you to the top of a volcanic tuff cone, where you’re rewarded with jaw-dropping views of Honolulu, Waikiki Beach, and the endless Pacific beyond.
I hiked it on a whim one morning, and let me tell you, watching the city come alive under the golden glow of sunrise is an experience I’ll never forget.
Here’s the thing about Diamond Head, though: it gets busy. And if you’ve been following this blog you know I don’t like crowds.
If you want to enjoy the trail without dodging crowds, go early, like sunrise early. Trust me, it’s worth setting your alarm for this one.
The trail is well-maintained but can be steep in places, with a mix of switchbacks, stairs, and even a cool, tunnel-like passageway toward the top.
Wear comfortable shoes, bring water, and don’t forget your hiking camera (or your phone, if you’re like me and have it glued to your hand).
Parking is limited at the trailhead, so either arrive before the rush or consider taking an Uber.
The entrance fee is a few bucks, but hey, it’s a small price to pay for those killer views. And if you’re wondering about difficulty, it’s totally doable. Even if you’re not in peak hiking shape.
Just take it slow, and you’ll get there.
Once I reached the summit, I stood there soaking in the panoramic views, feeling like I was on top of the world. If there’s one hike you shouldn’t miss on Oahu, this is it.
And talking about unmissable hikes in Hawaii, let’s talk about Pipiwai.
3. Pipiwai Trail (Maui)
- Distance: 4 miles (6.4 km) round trip
- Duration: 2–3 hours
- Best for: Nature lovers and waterfall chasers looking for an unforgettable experience
The Pipiwai Trail on Maui is like stepping into a storybook: towering bamboo forests that sway and sing in the breeze, a giant banyan tree that looks like it belongs in Middle-earth, and the grand finale, Waimoku Falls.
Waimoku Falls is a stunning 400-foot cascade that makes you feel like you’ve stumbled into paradise. This trail, tucked away in Haleakalā National Park, is one of my all-time favourites.
Walking through the bamboo forest was pure magic. The tall stalks creaked and swayed above me, and when the wind swept through, they created this soft, rhythmic music that felt almost otherworldly.
It’s one of those moments that makes you stop in your tracks and just listen. And then there’s the banyan tree. It’s massive, ancient, and absolutely awe-inspiring.
I spent way too much time there just staring up at its twisted branches.
If you’re planning to hike the Pipiwai Trail, here’s my advice: wear sturdy shoes because parts of the trail can be muddy, especially after rain.
Bring plenty of water, bug spray (the mosquitoes here don’t mess around), and maybe a light jacket since it can get cooler in the shaded forest. The trail is well-marked and easy to follow but take your time. You’ll want to soak in every detail.
If you love nature and don’t mind a bit of mud, this hike will leave you speechless.
4. Mauna Kea Summit Trail (Big Island)
- Distance: 13.5 miles (21.7 km) round trip
- Duration: 8–10 hours
- Best for: Experienced hikers seeking a challenging trek to Hawaii’s highest peak
Mauna Kea Summit Trail is not just a hike; it’s an adventure that feels like stepping onto another planet. I think it’s one of the best hikes in the world.
At 13,803 feet (4,207 meters) above sea level, this is the highest point in Hawaii, offering not only sweeping views but also some of the best stargazing in the world.
Hiking here was one of the most surreal experiences of my life. The volcanic landscape is barren yet breathtaking, with colours that shift dramatically as the sun moves across the sky.
But let me tell you, this hike is not for the faint of heart.
The high altitude can be tough, even for seasoned hikers like me, so preparation is key. If you’re considering this trek, spend at least a day or two acclimating to the elevation before you start. Trust me, it makes a huge difference.
The trail begins at the Mauna Kea Visitor Information Station, and while it’s well-marked, the rocky terrain and steep ascent make it a serious workout.
Remember to pack layers. Temperatures at the summit can drop below freezing, even during the day.
Bring plenty of water and high-energy snacks because you’ll need to stay hydrated and fueled on this long trek.
If you’re hiking for the stargazing, time your descent carefully or bring a flashlight or headlamp with extra batteries. It’s pitch dark on the trail after sunset.
My Pro Tip: Use a stargazing app along with the best hiking apps. That way, you won’t miss a thing.
Remember to take it slow and steady. Altitude sickness is no joke, and it can hit anyone.
I remember feeling lightheaded at one point and had to stop to catch my breath, but it was worth every step to stand at the summit and take in the jaw-dropping view of the Big Island below.
If you’re up for the challenge, Mauna Kea will leave you humbled and amazed.
5. Koko Crater Railway Trail (Oahu)
- Distance: 1.6 miles (2.6 km) round trip
- Duration: 1–2 hours
- Best for: Fitness enthusiasts and thrill-seekers ready for a challenge
The Koko Crater Railway Trail is a short hike, but don’t let the distance fool you. This trail is a beast!
Known locally as the “Stairmaster from Hell,” it’s a relentless climb up over 1,000 railroad ties to the top of Koko Crater. And yes, it burns, but the panoramic views at the summit?
Totally worth it. I’ll admit, my legs were screaming by the time I reached the top, but the sight of the turquoise ocean stretching endlessly below made me forget all about the pain.
Here’s what you need to know before tackling this thigh-burning adventure.
The trail can get hot—really hot. There’s zero shade, so start early in the morning or later in the afternoon to avoid roasting in the midday sun.
Bring more water than you think you’ll need, wear sunscreen, and maybe throw on a hat for good measure. And those railroad ties? They’re uneven and can be a bit sketchy in places, so sturdy shoes are a must.
The trickiest part is the “bridge” section. It’s an old railway trestle suspended over a gap. You can either brave it (carefully!) or take a side trail that bypasses it entirely.
I chose to go for it, holding my breath as I crossed, and let’s just say I’ve never been more focused on my footing.
Once you reach the summit, you’ll forget all about the climb.
The sweeping views of Hanauma Bay, Diamond Head, and the Pacific Ocean are absolutely breathtaking. Your legs may hate you for the trek, but your camera (and your soul) will thank you.
6. Sliding Sands Trail (Maui)
- Distance: 11 miles (18 km) round trip (to the summit and back)
- Duration: 6–8 hours
- Best for: Adventurous souls looking for a surreal, otherworldly experience
The Sliding Sands Trail, nestled within Haleakalā National Park, is unlike any of the best hikes in Hawaii I’ve ever done.
Walking this trail feels like stepping onto another planet. Think Mars, but with better views.
The volcanic landscape is painted in shades of red, orange, and black, and the sheer scale of the crater makes you feel tiny in the most humbling way.
This trail is as challenging as it is mesmerising. The descent into the crater is steep but manageable, with loose cinder underfoot that gives the trail its “sliding sands” name.
Just remember, what goes down must come up. The return trip is a serious workout. It’s not uncommon for hikers to underestimate how tough the ascent can be, so pace yourself and bring plenty of water and snacks to keep your energy up.
But there’s more.
The weather at Haleakalā is as unpredictable as it gets, with temperatures often dropping below freezing, even during the day.
I learned that the hard way when I started the hike under clear skies and ended up shivering in a sudden chill. A lightweight jacket or fleece is a lifesaver here.
The trail also has some incredible vantage points, so take your time to stop and soak it all in.
Sliding Sands is one of those hikes in Hawaii that stays with you.
It’s challenging, yes, but the experience of walking through this alien-like terrain is worth every step. If you’re looking for something truly unique, this trail is a must.
7. Pololū Valley Awini Trail (Big Island)
- Distance: 1.4 miles (2.3 km) round trip
- Duration: 1–2 hours
- Best for: Casual hikers seeking breathtaking views and a peaceful escape
The Pololū Valley Awini Trail might be short, but it’s packed with beauty.
This lush, serene hike takes you down a steep trail to a secluded black sand beach framed by dramatic cliffs and swaying ironwood trees.
It’s the kind of place that feels like it was made for quiet reflection. I still remember standing there, barefoot on the cool sand, listening to the waves crash as the wind rustled through the trees. It was pure magic.
This trail is great for beginners, but don’t underestimate the descent (or the climb back up).
The path can be slippery and steep in spots, especially if it’s rained recently, so sturdy shoes are a must.
It’s not a long hike, but take your time and enjoy the journey.
When you reach the beach, you’ll feel like you’ve stepped into a hidden world. The black sand is a stark contrast to the lush greenery around it, and the sound of the ocean feels like nature’s soundtrack.
It’s not a swimming beach (the currents are strong), but it’s perfect for relaxing, taking photos, or just sitting quietly and soaking in the beauty of the moment.
If you’re lucky, you might even spot wild horses grazing in the valley. It’s a little reminder of how untouched and magical this place is.
