The Lanikai Pillbox Hike and the Kaiwa Ridge Trail are short but sweet. The trail isn’t long, but the views? Wow! From there, the turquoise waters of Oahu and those twin Nā Mokulua islands are a real treat for the eyes. It used to be a World War II military post.
Back then, during WWII, this spot was quite significant. From these pillboxes, soldiers could monitor movements out at sea. It makes you wonder how different the atmosphere must have been compared to the peacefulness we feel now. I get a bit of a chill thinking about the history of this place.
So, while enjoying nature, you can also see remnants of history. Lots of people love coming here for sunrise. They say it’s fantastic!
The trail might be short, but don’t underestimate it. Some parts can be steep and slippery, especially after it rains. From my experience, shoes with a good grip are a must! Don’t forget to bring enough water. It can get pretty hot here, you know. Oh yeah, parking around Lanikai is tricky. It’s better to come early to snag a legal parking spot. We also gotta respect the locals, so no loud noises or illegal parking.
Where to Stay in Oahu
CWant to make the most of your hiking experience? Try staying around Kailua. It’s super close to the trailhead. So, if you want to catch the sunrise, you won’t have to rush from far away. If you prefer a livelier vibe, Waikiki is also a good option. There are tons of hotels and fun places to eat there. But heads up, it’s about a 30-minute drive to Lanikai.
- Kailua: Close to the trail, quieter atmosphere. Perfect if you want to focus on hiking and relaxing.
- Waikiki: More hotel options and nightlife. Great for those who like a more vibrant environment.
Important tip: check the route to the trailhead, considering traffic and parking availability.

Trail Overview
At first, you’ll walk near a residential area. Pretty soon, the trail starts climbing uphill on dirt. It’ll get you a little winded. But don’t worry, the views will instantly boost your spirits! Along the way, you’ll see the beautiful Lanikai Beach, the iconic Mokulua islands, and the vast Pacific Ocean. Our final destination is the two pillboxes on top of the hill.
From there, the view is seriously epic! Perfect for taking photos or just chilling and soaking in the natural beauty. From my experience, bringing a hat and sunscreen is super important because there’s not much shade. If it’s rained recently, the trail can be slippery, so be careful! It’s a shame you can only read about it here. The views in person are truly Instagramable!
I hope to add some photos or videos soon so you can see the beauty for yourselves. Trust me, pictures don’t fully capture the vibe up there!
Trail Distance & Duration
The total round-trip distance is about 1.6 miles. Usually, it takes me around 1 to 1.5 hours to finish, depending on how long we stop at the top for photos. The initial uphill climb is the most challenging. But after that, the trail levels out until you reach the pillboxes.
The relatively short distance makes it great for families or those new to hiking. Some continue hiking along the ridge beyond the second pillbox, following the Kaiwa Ridge. But that trail isn’t as well-maintained and is more challenging. If you’re not sure, sticking to the second pillbox is fine. The views are already incredible!
Trail Safety Tips
Safety first! Here are a few tips from my experience:
- Shoes: Wear hiking shoes or sneakers with a good grip. Don’t wear flip-flops!
- Water: Bring enough water, especially if it’s a hot day.
- Sun Protection: Sunscreen and a hat are a must! The Hawaiian sun can be intense.
- Check the Weather: Avoid hiking if it’s raining or has just rained heavily. It gets slippery!
- Stay on the Trail: Stick to the marked path to avoid damaging plants and preventing erosion.
- Respect the Locals: Remember, we’re passing through a residential area.
Keep the noise down and be respectful.
If we follow these tips, the hike will be safe and enjoyable!
Lanikai Pillboxes – What You’ll See
Once you reach the top, you’ll see old World War II pillboxes and two historic buildings. From here, the panoramic views of the coastline are amazing! You can see Lanikai Beach, which is famous, and the beautiful Mokulua Islands.
The first pillbox is a little lower and usually less crowded. It’s a good spot to enjoy the view more peacefully. The second pillbox is higher up and offers a broader view. It’s a popular spot for taking photos, especially during sunrise.
What’s cool is that these pillboxes often have fantastic graffiti art by local artists. So, there’s a touch of art mixed with history!
Continuing the Kaiwa Ridge Trail
For those who still have energy and want more adventure, you can continue along the Kaiwa Ridge past the second pillbox. From there, the views of the island’s windward side and the Koʻolau Mountains are also beautiful.
But like I said before, this trail isn’t as well-maintained. It can get overgrown, or the ground can be eroded. It’s only for experienced hikers who are prepared for a bigger challenge. If you’re unsure, just enjoy the views from the second pillbox. They’re already fantastic!
Sunrise at Lanikai Pillbox
Even though sunrise is more popular, sunset at the Lanikai Pillbox has its charm. The sun sets behind the Koʻolau Mountains, and the sky gets warm with orange colors. Usually, it’s not as crowded as sunrise. So, the atmosphere is more peaceful.
But remember, if you want to watch the sunset, bring a flashlight or headlamp for the way down. It’ll be dark. Always prioritize safety!
Trail Status & Regulations
The Lanikai Pillbox Trail is open year-round, but conditions can vary. After heavy rains, the trail can become muddy and slippery, increasing the risk of falls. It’s advisable to avoid hiking during or immediately after inclement weather.
No restrooms or water stations are along the trail, so plan accordingly. Additionally, the trail passes through residential areas; please respect private property and keep noise levels down.
Always stay on the designated path to preserve the environment and prevent erosion.
How to Get There
The trailhead for the Lanikai Pillbox Hike is near 265 Kaelepulu Drive in Kailua. From Honolulu, it’s about a 30-minute drive via the Pali Highway. If you want public transportation, take TheBus to Kailua and walk or bike to the trailhead. Bus schedules can change, so check ahead of time. Just a heads up, parking in the area is a real hassle!
Parking Info
Parking near the Lanikai Pillbox Trail is a nightmare! It’s a residential area, so there are a lot of parking restrictions. There’s no designated parking lot for the trail. Street parking is limited, and the rules are stringent. You can get a ticket if you park illegally.
Here are some tips from my experience:
- Arrive Early: If you can, get there before 7 AM. You might still find some empty spots.
- Park Legally: Don’t park in front of people’s driveways, near fire hydrants, or in no-parking zones. Pay close attention to the parking signs.
- Alternatives: Try parking at Kailua Beach Park and walking to the trailhead (about a 15-20 minute walk). It’s a bit of a walk, but it’s safer.
Be patient and careful when looking for parking!
