Koko Crater Railway Trail, Oahu: A Grueling Hike With A Stunning Payoff
Koko Crater Railway Trail
Koko Crater Railway Trail (or simply, Koko Crater Trail or Koko Crater Stairs) is easily one of the more popular but difficult hikes in all of Hawaii!
Why?
How often do you get to climb an ancient volcanic tuff, remnants of the very activity that formed the island of Oahu?
But that’s not the main attraction, it is the challenge! A physical and mental one.
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!
But if you do make it to the top, you’re rewarded not only with a sense of accomplishment, but with stunning panoramic views of the neighborhood, Hawaii Kai, Hanauma Bay, Diamond Head, the Honolulu skyline and virtually every major landmark on the island of Oahu!
Located on the southeast side of the island of Oahu, across from the famous snorkeling destination of Hanauma Bay, Koko Crater Trail is easily accessible from the tourist hub of Waikiki.

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.
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.
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.
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.
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.
Tips for Hiking Koko Crater Railway Trail
Unlike most other Oahu hikes, Koko Crater Railway Trail is difficult, and if you plan to hike it, make sure you come prepared!
Start Early or Late
With absolutely no shade, you are strongly advised to hike early in the morning or late in the afternoon to beat the heat.
The Sun Bum Original SPF 50 Sunscreen Spray, moisturizing with Vitamin E, is excellent for travel to Hawaii.
Gear Up for Success
Though short, the trail is steep and intense. Wear sturdy shoes with good grip—those old flip-flops simply won’t cut it.
The medium range Merrell Moab 3 Waterproof Hiking Shoe (men’s, women’s, men’s mid) is great for Hawaii’s trails through mud and streams. Or the high-end Salomon X Ultra 4 GTX Hiking shoes (men’s, women’s), which are also waterproof.
Improve your footing with this collapsible, high-end Black Diamond Trail Cork Trekking Poles, available for men and women.
Bring plenty of water (at least a liter per person) to stay hydrated, and pack a light snack for energy at the summit. A small towel or sweatband can also come in handy.
This Hydro Flask water bottle is light, stainless steel, wide mouth (you can add ice), with double-wall vacuum insulation (greatly refreshing for hikes in summer). You can also get it with a Flex Straw Lid!
Take Your Time
While the sheer incline can feel relentless, there’s no shame in stopping to catch your breath or admire the view behind you.
Take the Bypass on the Bridge Section
About halfway up, you’ll encounter a “bridge” where the steps span a gully with no ground underneath. If heights aren’t your thing, veer off to the dirt path on the left for a safer alternative.
