1. Diamond Head Trail
Hawaii’s most legendary hike—if you’ve seen a postcard of Waikiki, you’ve seen the views from here.
The 1.6-mile round-trip trail is doable in about an hour, but you’ll want to linger at the top.
Steep stairs, a tunnel, and a little sweat get you to the summit decks. This beginner-friendly adventure pays off with 360-degree views that’ll make you forget the crowds.
Best For: Those who want iconic city and ocean views from a historic volcanic crater—no experience required.
2. Makapuʻu Lighthouse Trail
Here’s an easy 2 and a half mile hike with a paved path and ocean air. You’ll follow the coast up to a classic red-roofed lighthouse built in 1909.
Bring binoculars—you might spot whales or even a monk seal basking below. On a clear day, Molokai and Lanai float on the horizon like mirages.
Best For: Families looking for a low-key walk with big coastal views and a solid shot at whale watching in winter.

3. Lanikai Pillbox Hike
The Lanikai Pillbox Hike serves up unreal panoramas of turquoise water and the Mokulua Islands. It’s an intermediate climb above one of Oahu’s prettiest beaches.
Historic military bunkers dot the trail, and the views of the windward coast are just…wow. If you’re into photography, you’ll run out of memory before you run out of scenery.
Best For: Jaw-dropping coastal views, snapping photos, and a moderate hike with a dash of history.
4. Waimea Valley Trail
The Waimea Valley Trail leads you to a waterfall that’s begging you to swim under it. The 1.9-mile round-trip stroll is paved and winds through lush botanical gardens.
Along the way, you’ll pass traditional Hawaiian structures and native plants before reaching the 45-foot falls. The paved path means it’s accessible for just about everyone.
Best For: Families craving an easy waterfall hike, a swim, and a little Hawaiian culture all in one.

5. Manoa Falls Trail
A classic waterfall hike that takes you through rainforest straight out of a movie set. The 1.8-mile out-and-back is just 18 minutes from Waikiki, so it’s pretty much a must-do.
Dense jungle, towering trees, and a 150-foot waterfall at the end. The moderate trail takes about an hour, and you don’t need to be an expert to enjoy it.
Best For: Anyone up for a rainforest adventure and a dramatic waterfall, all close to Honolulu.
6. Koko Crater Railway Trail
Not for the faint of heart—1,048 old railway steps straight up an extinct crater. It’s hot, steep, and there’s zero shade. Bring water and your stubborn streak.
Reach the 1,207-foot summit and you’ll get sweeping views of Hanauma Bay and the east Honolulu coastline. The 1.6-mile round trip is a serious workout—your legs will remember it.
Best For: Anyone who loves a tough cardio challenge and wants brag-worthy views at the top.

7. Manoa Middle Ridge Trail
One of Oahu’s tougher ridge hikes, but if you’re up for it, the views are wild. The trail starts at Alani Drive and climbs through native forest, mud, and some rope-assisted sections.
At 2,013 feet, the summit gives you a full sweep of Honolulu, Diamond Head, and the windward coast. On a clear day, you’ll be glad you pushed through the hard parts.
Best For: Experienced hikers ready for a challenge and summit views that go on forever.
8. Kaʻena Point Trail
The Ka’ena Point Trail is all about wild coastline and wildlife. This flat, family-friendly trek follows an old railroad bed through a protected sanctuary.
You can start from either the north shore or west side for a 5-mile round trip. At the end? Ocean views where north meets west, and maybe an albatross or monk seal if you’re lucky.
Best For: Those after easy coastal hiking, wildlife encounters, and dramatic cliffs far from the crowds.

9. Olomana Three Peaks Trail
The Olomana Three Peaks Trail is not for the timid—think ropes, scrambles, and narrow ridges. It’s four and a half miles round trip with 1,550 feet of gain to the first peak alone.
Rope climbs, exposed rock faces, and huge windward views. The third peak is the toughest—most people call it a day after the first or second summit.
Best For: Hikers who want adrenaline, challenging scrambles, and mind-blowing views of Oahu’s coastline.
10. Ehukai Pillbox Hike
The Ehukai Pillbox Hike gives you North Shore views from a graffiti-covered bunker. It’s just over a mile up, but the payoff is big: Sunset Beach, Banzai Pipeline, and rolling surf below.
About 30 minutes to the top with 800 feet of elevation. Trail head can be accessed by Sunset Beach Elementary and follow the pink ribbons—easy enough, but you’ll break a sweat.
Best For: Epic sunsets, North Shore photo ops, and a moderate climb that won’t eat your whole day.

11. Mount Kaʻala Trail
Oahu’s highest point at 4,026 feet is a beast. The 7-mile round trip gains 5,000 feet and throws in ropes, mud, and boulders for good measure.
Scrambling and bouldering sections make it one of the toughest hikes on the island. Bring gloves for the ropes and boots for the mud—you’ll earn those summit bragging rights.
Best For: Hardcore hikers chasing panoramic island views and a real sense of accomplishment at Oahu’s highest summit.
12. Aiea Loop Trail
The Aiea Loop Trail is a 4.4-mile forest walk in Keaiwa Heiau State Recreation Area. Shaded, mellow, and perfect if you want distance without the drama.
Midway, you’ll hit a lookout with views of the H-3 highway slicing through the Koolau Mountains. Pearl Harbor and Diamond Head pop up from other vantage points too.
Best For: Families with kids, beginners wanting a longer hike, or anyone looking to avoid the crowds and the sun.

13. Puʻu Pia Trail
Easy-to-moderate and tucked away in Manoa Valley, this trail is all about peaceful mountain views. You’ll climb just 205 meters over 2 miles for a panorama of the Ko’olau range.
Way less crowded than Manoa Falls, so you can actually hear the birds. Kids can handle this one—it’s about an hour and a half round-trip, give or take.
Best For: Families who want easy mountain views and a quieter trail than the usual Oahu hotspots.
14. Waimano Falls Trail
Hidden in the heart of Waimano Valley, this short waterfall hike brings some real wow for the effort.
It’s only about a 45-minute trek downhill, winding through greenery that feels straight out of a movie set.
On a good day, you might spot folks lining up for a go at cliff jumping—or maybe you’ll be tempted yourself. The falls spill into a series of pools, all begging for a post-hike dip.
Best For: Adventurous types craving waterfalls, swimming holes, and a shot of adrenaline—all in less than an hour.
