Although this column was suppose to be about Oneawa Hills, The Hawaiian Trail & Mountain Club makes an annual climb to the top of Koko Crater on New Year's day, and it seemed more appropriate to feature this hike early in the year. Oneawa Hills will appear next month.
Koko Crater, rising 1208 feet above eastern Honolulu, holds a commanding view over Hawaii Kai, Kuapa Pond, Hanauma Bay, and Koko Head. The interior of the crater is host to one of Honolulu's four botanical gardens, this one featuring dry area plants.

The Koko Crater summit contains the remains of an extensive bunker complex, dating from World War II. The bunkers were served by an inclined railway, pulled up by a heavy winch. The rail track is still in place, on the southwest side of the mountain, and is used in the descent for those who want to make a loop hike. The route described here is an exciting adventure, with outstanding views, but it is not for children or those nervous about heights. [A safer climb to the summit can be made by using the rail route to and from the peak]. I am not able to describe the route in this article, as the way is unmarked, and much of it depends on previous knowledge. Do this hike with a club, or someone who has done it before and knows the way.
The route begins near the Halona Blowhole, and that is where we parked.

Getting ready for the climb
From the parking lot, we walked back along the highway toward town a short distance, then turned right onto a ridge heading toward the mountain.

Connecting ridge leading right, toward the main slope.

The toughest part of the route is the crossing of a steep and narrow rock arch, which bridges a gulch to connect with the main slope. A fall here could cause serious injury, and it has turned back many a hiker. There are some small steps carved into the rock at irregular intervals, which help somewhat, but it is an exposed climb, which should not be attempted in wet or very windy conditions. For our hike, an advance party strung a safety rope over the worst part.

Made it - but don't look back!
Once across the arch, the route gets less precipitous, but it is still steep and rocky.

"The Knob" at the top is the same one seen from the inside of the crater in Photo 2, and will be where our group will reach the crater rim.

At last! We reach the crater rim. "The Knob" is above, with the summit in the distant right. Going will now be a little easier.

When we finally reached the bunkers on the summit, the weather began to cloud up, but it never obstructed the fine view.

Once everyone reached the bunker, a celebration is in order.

A toast to the New Year!
After drinking, snacking, and photo-snapping, it was time to leave the mountain. We descended via the rail track, which comes out near the Koko Head rifle & pistol range and the former Job Corps site.

Vegetation almost covers the tracks

Rather than return on the road, we took advantage of a little-known cave which allowed us to emerge at the bottom of a cliff onto the rocky seashore.

We stop to check out a fishermen's camp
Finally, at "From Here to Eternity" beach, we climb back to the Halona Blowhole parking lot - ending a long and satisfying day.
