Hiking the Koko Crater Arch Trail on Oʻahu
Distance: 1.0 miles / 1.6 km
The Koko Crater Arch is one of the best easy sunrise hikes on Oʻahu, and in my opinion, it’s even easier than the neighboring Makapuʻu Lighthouse Trail.
Koko Crater Arch Trailhead Parking
Parking for the Koko Crater Arch is located in a few small turnouts off of Kalanianaʻole Highway near the Hālona Blowhole.
If parking in the turnouts is taken, it’s best to park in the Hālona Lookout parking lot.

Hiking the Koko Crater Arch Trail
The Koko Crater Arch Trail begins at either one of two small ridges next to the turnouts.
The main ridge that’s closer to Hālona is the one shown below, but eventually, they both come together a little before the arch.
On the other side of the guard rail, the trail simply follows the ridge up the sides of the popular Koko Crater.
The area in the photo below on the right is where both ridges come together.
There are two ways to get underneath the Koko Arch, but in my opinion, the route to the right, shown first, is the easier of the two.
I say this because the hike up to the base of the arch gets very steep, while the path to the right is much milder.
Koko Crater Arch
In my opinion, sunrise through the far side of the arch is one of the best ways to start your day on Oʻahu!
This is the climb up to the top of the arch, and the path on the left.
The climb to the top of the Koko Arch is very steep, and the drops on either side can be dangerous.
That being said, the trail doesn’t necessarily stop at the top of the arch. For the most adventurous type of person, you can climb all the way to the Koko Rim.
Native Plants on at Koko Crater Arch
Most of the slopes along the sides of Koko Head are dominated by non-native/ invasive species like haole koa.
However, there are still a few native species that you can find such as ʻIlima and Alena.
