Getting Ready for Oahu’s Trails
Before you hit the trails, it’s important to prepare. You’ll need the right gear, an understanding of the weather, and some key safety tips to make the most of your Oahu hiking adventure.
What to Pack
Packing the right gear is crucial for a great hike. Here’s what you should bring:
• Hiking shoes with good traction
• A comfortable backpack
• Plenty of water (at least 1 liter per hour of hiking)
• Snacks like trail mix or energy bars
• Sunscreen (SPF 30 or higher) – this one is my favorite
• A wide-brimmed hat for sun protection
• A light rain jacket (just in case)
• Your phone for photos and emergencies
• A small first aid kit (optional)
Also, don’t forget to wear breathable, moisture-wicking clothes. Layers are your friend, as you can easily adjust to changing temperatures.
Understanding the Weather
Oahu’s weather can be tricky, so it’s smart to check the forecast before you go. Here are some tips:
• Mornings are usually the best time to hike, with clearer skies and cooler temps.
• Afternoon showers are common, especially on the windward side.
• It can be hot and humid, so start early and bring extra water.
Remember, mountain weather can change quickly. Even if it’s sunny at the trailhead, it might be cloudy or rainy at higher elevations. Be prepared for all conditions!
Safety First: Tips and Essentials
Staying safe on Oahu’s trails is super important. Follow these tips:
• Tell someone where you’re going and when you’ll be back.
• Stick to marked trails and don’t wander off.
• Check trail conditions before you start. Some trails close after heavy rain.
• Bring a fully charged phone, but don’t rely on it for navigation.
• Start early so you finish before dark.
• Respect wildlife and don’t feed any animals you see.
If you’re new to hiking or want to learn more about the area, consider joining a guided hike. Local guides can share cool facts about Oahu’s nature and history while keeping you safe.
Iconic Hikes in Oahu, Hawaii
There are tons of hiking spots in Oahu that offer breathtaking views. Here are 3 of the most iconic Oahu hikes.
Diamond Head Crater
Diamond Head Crater is a must-do hike for any visitor to Oahu. This 1.6-mile round trip trail takes you to the summit of an extinct volcano and is one of the most popular hikes in the entire island.
You’ll climb 560 feet in elevation, tackling stairs and steep inclines to get to the top of Diamond Head. The effort is worth it for the stunning 360-degree views of Waikiki Beach and the Pacific Ocean.
The trail can get crowded, so try to arrive early. Bring water and wear good shoes. You’ll pass through a tunnel and old military bunkers on your way up.
At the top, take in the incredible sight of Honolulu sprawled out below you. It’s a perfect spot for photos and catching your breath before heading back down.
Manoa Falls Trail
The Manoa Falls Trail takes you through a lush rainforest to a beautiful 150-foot waterfall. This 1.6-mile round trip, very popular hike is relatively easy and great for families.
You’ll walk through a bamboo forest and cross small streams. The trail can be muddy, so wear shoes with good traction.
Along the way, keep an eye out for native plants and colorful birds. The dense jungle feels like something out of Jurassic Park.
When you reach the falls, you’ll be rewarded with a misty view of water cascading down a sheer rock face. It’s a refreshing sight, especially on a hot day.
Remember to stay on the marked trail and don’t climb on the rocks near the falls. Safety first!
Koko Crater Trail
For a real challenge, tackle the Koko Crater Trail. This steep 1.8-mile round trip hike follows over 1,000 old railway ties straight up the side of Koko Crater.
It’s a tough climb, but the views at the top are incredible. You’ll see Hanauma Bay, Sandy Beach, and the eastern coastline of Oahu.
Bring plenty of water and take breaks as needed. The trail is exposed, so start early to avoid the midday heat.
Take time to explore and soak in the panoramic views before carefully making your way back down.
East Oahu Adventures
East Oahu offers awesome hikes with amazing views. You’ll find trails that take you up to old military bunkers, along steep ridgelines, and to scenic lighthouses. Each hike gives you a different look at Oahu’s beautiful coastline.
Lanikai Pillbox Hike
The Lanikai Pillbox hike is a must-do when you’re in East Oahu. It’s pretty short but it’s a steep climb, taking about 30-40 minutes to reach the top. You’ll climb up to two old military pillboxes that give you stunning views of Lanikai Beach and the Mokulua Islands.
The trail can be rocky and slippery, so wear good shoes. Once you reach the pillboxes, take a break and soak in the views. You can see the bright blue ocean and white sand of Lanikai Beach stretching out below you.
After your hike, head down to Lanikai Beach for a swim. It’s one of the prettiest beaches on Oahu with soft sand and calm waters. Perfect for cooling off after your climb!
Olomana Three Peaks Adventure
If you’re up for a challenge, try the Olomana Trail. This hike is tough but rewarding – definitely gives you a good workout. It’s about 4.5 miles roundtrip and takes you up three steep peaks. Each peak gets harder, so many people only do the first one or two.
At the top, you’ll be rewarded with the most beautiful views. You can see all the way to Kailua and the windward coast. But be careful – parts of the trail are very narrow with steep drop-offs on both sides.
Note: Only attempt this hike if you’re in good shape and have previous hiking experience as it is not an easy trail. I wouldn’t recommend this trail if you are with small children. Bring lots of water and start early to avoid the heat. The trail can be muddy and slippery, so hiking boots are a must.
Makapu’u Lighthouse Trek
For an easier hike with great views, check out the Makapu’u Lighthouse trail. This paved path is about 2 miles round trip and good for all skill levels. It’s even stroller-friendly!
As you walk up, you’ll get awesome views of the coastline. Look for whales in the winter months. At the top, you’ll see the red-roofed Makapu’u Lighthouse perched on the cliffs.
The lighthouse was built in 1909 but is now automated. You can’t go inside, but the views from the lookout are incredible. On clear days, you can see Molokai and Lanai islands.
After your hike, cool off at nearby Makapu’u Beach. The waves can be big, so be careful if you go in the water.
