Koko Crater Trail is the abandoned remnants of an old tramway track that carried military supplies to a lookout post manned during World War II.
The “steps” of the Koko Crater Trail are actually old railroad ties, wooden rectangular planks arranged perpendicular to the rails.
The steps, sometimes called Koko Crater Stairs, rise almost vertically into the sky to the summit of Koko Crater and therein lies the challenge!

Oahu’s Koko Head Crater Trail isn’t for the faint-hearted, but if you’re up for a heart-pounding, leg-burning adventure, this is your ultimate hike.
Rising 1,200 feet above sea level, the trail demands that you conquer a staggering 1,048 steps to the summit — all remnants of an old military railway used during WWII.
These steps aren’t your usual kind; they’re rugged, uneven railroad ties, worn over time and demanding serious grit from those who climb them.
But the reward? Sweeping, drop-dead views of Honolulu’s eastern shore.
Cruise aboard a 50-foot catamaran and look for dolphins and turtles year round, plus whales in the winter. Look through magnifying portals in the glass bottom for fish and colorful coral! Leaves from Kewalo Basin Harbor in Waikiki, easy to access. ⛴️ 🌊 ⛴️
The Climb Begins
You’ll start the Koko Crater Trail hike from the back of the baseball field at Koko Head District Park, where there’s plenty of parking and restrooms.
Follow the signposted trailhead, and you’ll soon be walking along the railway tracks.
The path starts easy enough — a deceptive, level stretch — before the incline kicks in and the real fun begins.
Keep an eye out for Ilima, Oahu’s vibrant endemic flower, brightening up the lower trail with pops of yellow.
Parasailing over the beautiful blue waters off the Waikiki Coast is one of the most exciting things to do in Oahu! This popular parasailing tour has been operating since 1977 and features your choice of an 800-foot or 1,200 foot line. 🪂 🪂 🪂
The Journey Gets Steeper
As you press upward, each step becomes a test of strength and willpower.
About halfway, you’ll reach a famous “bridge” section — the tracks rise above a gap, leaving nothing beneath but open space.
Not for the vertigo-prone!
For those who’d rather keep their feet firmly on the ground, there’s a bypass on the right, but it’s a bit rocky and narrow, so watch your step.
Past this heart-thumping section, the trail’s incline only sharpens, requiring hands, feet, and determination.
And just when you think it’s over, brace yourself for gusty winds near the summit.
Based in Waikiki and want to explore the rest of Oahu without worrying about logistics? This highly-rated circle island tour stops at top spots like Diamond Head, Halona Blowhole, Valley of the Temples, Mokoli’i Island, and Waimea Falls! 🚌 🏝️ 🚌
At the Summit: Views that Take Your Breath Away (Again)
The top of Koko Head is like a reward for every burning muscle.
From this vantage point, soak in panoramic views that stretch from Hanauma Bay and Sandy Beach to Makapu’u Lighthouse and, on clear days, even parts of Molokai glimmering on the horizon.
Wander around the old WWII bunkers — relics of another era — and pick a spot to catch your breath, snap a few photos, or just revel in the beauty of it all.

Sights Along the Way
On your way up (and down!), the sights evolve with every step. Early on, gaze down at the Koko Crater Botanical Garden nestled within the crater itself, a 60-acre oasis brimming with dryland plants from around the world.
To your left, the scenic expanse of Hawaii Kai Marina and Maunalua Bay glistens in the sun, perfect for spotting turtles and dolphins below.
As you climb higher, to the right lies the sparkling Hanauma Bay — one of the island’s top snorkeling spots — followed by Sandy Beach with its powerful surf and, finally, the famed Makapu’u Lighthouse on your left, a beacon on Oahu’s rugged coastline.
Want to hit the waves at the place where surfing was reportedly born? Book this small-group surfing lesson with a qualified instructor and enjoy the ultimate Hawaii vacation experience! Lessons are offered right on Waikiki Beach. 🏄 🏄🏻♀️ 🏄🏽
The Descent: Choose Your Path Wisely
To return, most hikers retrace their steps back down, but there’s also a crater rim trail for the adventurous.
Taking the railway back down is steep, so tread carefully — balancing with your hands if needed. For the daring, the rim trail loops around, offering even more spectacular views but with sharp drops and loose footing.
Either way, keep a steady pace, take breaks, and drink in every moment of this one-of-a-kind hike.
In short, Koko Head demands effort but offers a payoff that’s pure Oahu magic — a challenging climb with jaw-dropping sights that make every step worth it.

Take Your Time
