Every year on November 17th, outdoor lovers across the country lace up their boots for National Take a Hike Day — a day dedicated to exploring trails, soaking in the beauty of nature, and reconnecting with the world beyond our screens.

If you’re lucky enough to be on Oʻahu, there’s no better place to celebrate! From coastal lookouts to lush rainforest paths, this island paradise offers hikes for every skill level and sense of adventure. Whether you’re chasing waterfalls or sunrise views, Oʻahu’s trails deliver some of the most breathtaking scenery in the world.

So, in honor of #NationalTakeAHikeDay, here are five of the best hiking spots in Oʻahu to help you hit the trails and make the most of your island adventure.

1. Makapuʻu Point Lighthouse Trail

Location: Southeastern Oʻahu – Waimānalo
Difficulty: Easy | Distance: ~2 miles round trip

This paved trail is perfect for a relaxing, family-friendly hike. As you ascend, the stunning ocean views stretch out before you, and during whale season (December–April), you might even spot humpback whales breaching offshore. The trail ends at the historic Makapuʻu Lighthouse, standing proudly against the sea cliffs.

Pro Tip: Go early for sunrise — the pink and orange hues over the Pacific are unforgettable..

2. Lanikai Pillbox Trail (Kaiwa Ridge)

Location: Kailua
Difficulty: Moderate | Distance: ~1.5 miles round trip

Short but steep, this ridge trail rewards hikers with panoramic views of Lanikai Beach and the Mokulua Islands. Along the way, you’ll pass old World War II-era pillboxes that now serve as colorful lookout points and photo ops.

Pro Tip: Start your hike before dawn — watching the sunrise from the top is one of the most magical experiences on the island.

3. Mānoa Falls Trail

Location: Mānoa Valley, Honolulu
Difficulty: Easy to Moderate | Distance: ~1.6 miles round trip

If you love lush greenery, this trail is for you. The Mānoa Falls Trail takes you through a rainforest of bamboo and tropical flora before leading you to a 150-foot waterfall — a scene so cinematic it’s been featured in movies like Jurassic Park.

Pro Tip: It can get muddy, so wear sturdy shoes you don’t mind getting dirty!

4. Koko Crater Railway Trail (Koko Head Stairs)

Location: Hawaiʻi Kai
Difficulty: Challenging | Distance: ~1.8 miles round trip

Looking for a workout with a view? The Koko Crater Trail is a local favorite. Made up of over 1,000 “stairs” — old railroad ties that run straight up the crater — this hike will get your heart pumping. At the top, you’ll find 360-degree views of Oʻahu’s southeastern coast and Hanauma Bay.

Pro Tip: Bring water and go early to avoid the midday heat. The climb is tough but worth every step!

5. Diamond Head State Monument (Leʻahi Summit Trail)

Location: Waikīkī / Honolulu
Difficulty: Moderate | Distance: ~1.6 miles round trip

No Oʻahu hiking list would be complete without Diamond Head, the island’s most iconic trail. This well-maintained path takes you inside an ancient volcanic crater, through tunnels, and up to historic bunkers. At the summit, you’ll be rewarded with breathtaking views of Honolulu and the turquoise ocean beyond.

Pro Tip: Reservations are required for non-residents — book ahead and plan for early morning hikes to beat the crowds.
