If you’re heading to Oahu’s North Shore and you want a hike that delivers big views without taking up your entire day, don’t skip the Ehukai Pillbox Trail.

It’s right near the famous Banzai Pipeline, minutes from Sunset Beach, and it punches way above its weight for such a short hike.

The first time I did this trail, I remember thinking, “Okay, this is going to be a quick little workout.” And yes, it is quick…but wow, it’s also stunning. You get panoramic views of the coastline, rolling green hills behind you, and that unreal turquoise water in front of you. It’s moderately challenging (especially at the start), but totally doable if you’re in decent shape.

I’d recommend this hike for adventurous beginners, anyone short on time, photographers, history lovers, and honestly anyone who just wants a solid North Shore experience without committing to a half-day trek. If you’re into WWII history, epic viewpoints, or colorful graffiti art on old bunkers, this one’s for you.

Why This Hike Is Worth Doing

Oahu has a handful of pillbox hikes…those old WWII bunkers perched on ridgelines around the island. The most famous is the Lanikai Pillbox, but honestly? I think Ehukai is a very close second.

What makes this one special is the location. You’re right on the North Shore, overlooking some of the most iconic surf spots in the world. In the winter, you can literally watch massive waves rolling into the Banzai Pipeline from above. It’s such a cool perspective.

The trail leads you to two military bunkers built during World War II. They were originally used as lookout points to defend the island from potential attacks. Today, they’re colorful, graffiti-covered landmarks that double as epic photo backdrops.

And the views? Sweeping golden beaches, bright blue water, and lush green mountains behind you. It feels like you’re standing in the middle of a postcard.

Trail Description

The trailhead is easy to find. You’ll turn into the parking lot behind Sunset Elementary School (again, don’t go through the gates into the school yard). There’s a small row of parking spots in front of the park — maybe a dozen — and more parking across the street if those are full.

From the lot, you’ll see a well-worn dirt path heading into the trees. And almost immediately… it starts climbing.

The first section is the hardest. It’s steep, rocky, and full of exposed tree roots. There are ropes in some of the trickier areas, which definitely help. If you’re in decent shape, it’s manageable — especially since it’s short. But don’t let the short distance fool you. Your legs will feel it.

If it’s dry, it’s a fun little scramble. If it’s been raining? Totally different story. The dirt turns slick fast. I’ve done it after a drizzle and it was SUPER slippery — the kind where you’re questioning every step. If it’s wet and you still decide to go, take it slow, use the ropes, and accept that you’re probably going to get muddy. On the way down, I sometimes “crab walk” certain sections rather than risk sliding.

As you climb higher, the trees thin out and the views start opening up. And then suddenly, you’re at the first pillbox.

The bunkers themselves are covered in colorful graffiti from local artists. It’s actually pretty cool — bright blues, reds, and yellows against the ocean backdrop. You can climb on top (carefully) for even better views.

There’s a second pillbox a little farther along the ridge. Both offer slightly different angles of the coastline. At the top, the wind can be strong, but that breeze feels amazing after the climb.

Things I Love About Ehukai Pillbox Hike

The Views: Seriously top-tier North Shore panoramas. You can see golden beaches, rolling surf, and lush hills all in one frame.
Short but Rewarding: You don’t have to dedicate half your day. It’s quick and satisfying.
WWII History: The bunkers add a layer of meaning and history. It’s not just a pretty viewpoint.
Photo Opportunities: Between the graffiti-covered pillboxes and the coastline, it’s a photographer’s dream.
Great Workout: That initial incline will get your heart pumping.
No Permit Required: Easy, accessible, and simple to plan.

Things That Could Be Better

Limited Parking: The small lot fills up quickly, especially on weekends.
Slippery When Wet: I can’t stress this enough. Rain turns this into a slip-and-slide.
Steep Start: If you’re not into quick, intense climbs, the beginning might feel intimidating.

Tips for Hiking This Trail

Go Early: Start in the morning to beat the heat and the crowds.
Check the Weather: Avoid this trail after rain if possible. Dry conditions make a huge difference.
Wear Proper Shoes: Trail shoes with good grip are a must.
Use the Ropes: They’re there for a reason.
Take It Slow on the Way Down: Descending is trickier than climbing up.
Bathrooms: There are restrooms with running water at the park by the trailhead, which is super convenient for washing up after getting muddy.

I’ve made it my job for the last 10 years to explore Maui.

And after hundreds of beach days, rainforest hikes, snorkeling trips, and reconnaissance missions to find the best hotels… and mai tais… I put everything I know into one place.

This is my Maui Digital Map — hundreds of my favorite spots. Beaches, snorkeling spots, hikes, farm tours, scenic drives, places to eat.

Yes, I share hidden spots I don’t talk about so much on social media…but also—tourist doesn’t have to be a dirty word. Popular places are popular for a reason.

So I break down what’s worth it, what’s not, where to spend your money, where to save it, and how to avoid crowds at some of Maui’s most popular (and best) places so you actually enjoy your time.

I’m also sharing all of my travel guides on when to go, where to stay, detailed hotel reviews…
plus dozens of itinerary options based on where you’re staying and what you love to do.
