What’s New at the Top of the Koko Crater Trail

Just in time for the 4th of July long weekend, the city Parks & Recreation Department unveiled a brand-new viewing platform complete with railings. This replaces a larger but unstable metal grate that wasn’t designed to hold crowds of hikers. The $426,800 project was completed over several weeks in June 2023. The city congratulated SEY Engineers and Kaikor Construction Co. for the quick work.

Keep It Calm and Clean
The city once again consulted with members of the nonprofit volunteer group Kokonut Koalition, which refurbished the tramway trail in 2021. Koalition president Lena Haapala offers a couple friendly reminders for visiting the refurbished trail: “It’s a much smaller space, so please be courteous to others who want to take photos on the platform. Always be respectful and be sure to take your trash down.”

The Experience

Call it the Koko Crater Stairs or East Side’s grueling stairmaster, this heavily trafficked trail consists of 1,048 steps from an abandoned tramway track. Whether you’re looking to get your cardio in for the week or enjoy a great view of Waikīkī to Alan Davis beach, you’ll definitely have a chance to experience both as you ascend to a 1,200-foot elevation at the top.

The first half of the trail starts off with a moderate incline, lined with wild flowers and electric poles, evenly spaced to serve as good markers (and motivation) for hikers. The degrading railway steps have been renovated and repaired by community members for a safer ascent to the top. Toward the middle of the trail, the ground underneath the steps drops away—you can either brave the levitating steps or veer right for a safer dirt path.

The last half offers an unforgiving set of steep steps where the high-level cardio kicks in. Enjoy the increasingly wider view of Hanauma Bay all the way to the back of Diamond Head as you take water breaks.

The Payoff

At the top, climb up to the right and enjoy gentle winds that cool you off and a sprawling ocean view behind the crater. Watch the waves form and break at Sandy’s and follow Kalaniana‘ole Highway up to the beginning of the Makapu‘u Lighthouse Trail. Snap a pic and take time to enjoy the view knowing you’ve just completed nature’s daunting stairmaster.

Tips
- Thoroughly lather yourself with sunscreen and wear a hat and protective clothing. Take your sun protection a step further and start the hike in the early morning or evening, or pick a day with some cloud cover.
- Be cautious or avoid the trail after/during the rain to avoid a dangerous slip.
- Pack your trash and bring any other trash down the stairs. There are no trash cans at the top.
- On the way down, pace yourself and go slow. Be mindful of people trying to pass.

The History Behind the Stairs

Before the track of railway stairs became known as a hiking trail, it was used by the National Guard, the Federal Aviation Administration and the Air Force to carry personnel and supplies up and down to the military bunkers at the summit of Koko Crater during World War II. The facility and surrounding land was given to the city of Honolulu in 1966 and renamed Koko Head Regional Park.
Fun fact: Koko Crater and Koko Head are two different mountains. Koko Crater was formerly known as Kohelepelepe and is home to the Koko Crater Botanical Garden and Koko Crater Stables. Koko Head is across Kalaniana‘ole Highway and overlooks Hanauma Bay.
Map & Directions

Turn into the Koko Head Regional Park and park at the lot nearest the end of the road. Walk toward the end of the road and turn left at the fork (turning right will take you to the highway), onto a dirt trail that is about 100 yards long, until you reach the foot of the stairs.
