We all dithered and dickered over the venue for Princess’s birthday hike today. It was too dry for the original waterfall hike, other venues were rejected before finally settling on a large and extinct tuff cone on the East side of the island.

Koko Crater

There was some apprehension about certain individuals that were loitering near the botanical garden entrance but a military connection was soon formed and such feelings soon evaporated as we headed for the marked trail.

Koko Crater Rim

We waited for the group to collectively come together as some of them had taken the scenic route or as they say they were “exploring.”

Shaking off the jet lag, I decided to do an easy stroll around the fringed vulva and look for another hole. Met up with Kenny, Marilyn, and Scott at the botanical garden to kick off our hike.

Koko Crater Rim

We all scrambled up our own path to reach the top.

We scrambled down the arch as three other hikers came up the arch. Turned out later that I was chatting with one of the guys online about possibly hiking together at a later date. Small world.

Koko Crater

The terrain was uneven, loose rocks underfoot and annoying and irritating dry bushes blockading the way. Edgar and grandkids and Marilyn decided to turn around and call it a day. We traversed up and down multiple ridges before descending down to the cave.

Koko Crater

Yay. Somebody told me about this cave almost ten years ago and thanks to Kenny spotting it earlier, I found myself standing in this natural void in the volcanic tuff. The elusive inhabitant was not at home. Perhaps it’s no longer occupied anymore.

Koko Crater

Deja vu. Nobody else wanted to come and share the moment with me as it started raining. Upon rejoining the other two, I discovered my car key was missing. Back to the cave and nowhere to be found. Scrambled back up the ridge and Kenny found it amongst the bushes as we made our way back. A needle in the haystack. Mahalo! Scotty suggested I should air tag my keys like he does. Filed under procrastination. One day.

All pau

We climbed our way down from the arch to the highway and walked back to Scotty’s car to get a ride back to our cars. Thanks to everybody for a fun day.

Addendum – October 29, 2025

Met up with Chico and Kenny to check on progression and occupancy as we returned to the volcanic crater whose age has ranged from 7,000 to 67,000 years old.

We did two short hikes on the day that has its origins in pagan festivals that celebrated spring and fertility, hence the easter bunny and was later co-opted by Christianity to celebrate the resurrection of Jesus Christ.

Met up with Edgar and Jeremy at the State Recreation Park where a quick morning shower dampened the grounds before our hike.

We soon ran into two Navy guys, Cavyn and Evan, who were stymied by a particular rock on the rim. We invited them to join us and they accepted.

GPS Tracks

Our rim hike around the crater whose original Hawaiian name was Kohelepelepe which loosely translates to fringed vulva or flying vagina covered 2.16 miles. How did it gets it name? I won’t go into the mythology, but just look at the tracks and take a wild guess. Post hike meal at Zippy’s. It wasn’t Thai but close enough. Two short and fun hikes with good company.

I met up with Glenn and Chris at the Koko Head Botanical Gardens to do a nice Sunday stroll up the entire Koko Crater rim, we have hiked up from the arch and from the tracks. But never have we completed the entire Koko Crater rim.

Koko Head Botanical Gardens and Makapu’u

The grassy and kiawe trees eventually changed to the rocky and cacti inhabited rim of Koko Crater or Kohelepelepe which means traveling vagina. Take a look at Koko Crater on a topographical map and you will see why.

Cracked Rim

Going up the rim presents an interesting view of the fractured rim and presents numerous climbing possibilities. This is a different perspective of Koko Crater that you don’t experience if you just go up and down the tracks.

Kamiloiki and Kamehame Ridges

Our hike was blessed with a nice thick cloud layer which blocked most of the scorching sun rays. Unfortunately, vog conditions were in effect as well, producing hazy viewing conditions.

A little climbing

Heading to the lookout is a nice and steady climb up the rim, punctuated by several opportunities to rock climb or for those less inclined, to simply contour around.

Going into the bunker

We had brough headlamps and flashlights to root around these long abandoned bunkers at the top of the summit that was left over from World War 2. The tunnel leading to the bunker was actually very low, forcing us to crouch over as we stepped on scattered debris and rubbish on the floor that was partially illuminated by our headlamps.

Inside the bunker

If you’re claustrophobic and nyctophobic, going into these bunkers would not be a good idea. It was pretty cool and anti-climatic at the same time when we got to the bunker, as it was just filled with more debris on the floor and a shaft that went up to the surface. Two things prevented me from trying to climb up the shaft, the bottom part of the ladder was torn off and the middle of the shaft looks like it’s blocked by some sort of ventilation shaft.

Top of Puu Mai

The top of Puu Mai was teeming with hikers that had come up from the tracks. This hike gets a lot of activity, especially on the weekends. I can see why, as it’s a relatively short hike that has payoffs with great views waiting at the top.

Hanauma Bay and Koko Head

As we started to climb down the rim, the plinking and cracking sounds coming from the rifle range were really cranking that morning. Must be a result of all those increased gun sales.

Counter-clockwise on the rim

We spent some time at the top, checking out the views and enjoying the breezy tradewinds that had just picked up. Going down the rim, the rocky parts continued until the knob formation.

Molokai

Once past the knob, the rim leveled off and it was a nice gradual slope on the way back down as we caught views of Halona Blowhole, Sandy Beach and the islands of Molokai, Lanai and Maui. We got back to our cars around 9:30am and had brunch at Zippy’s, thanks Glenn!

This was my third time hiking Koko Crater. The first time I walked up and down the tram tracks. The second time we had hiked up the side of Koko Crater and walked down the tram tracks. This time, the plan was to climb up the side of Koko Crater and go down the rim and end up in Koko Crater Botanical Gardens.

Fishing Shrine

We staged one car at the Koko Crater Botanical Gardens which is right off Kealahou Street by the Queen’s Gate neighborhood in Hawaii Kai and drove to the parking lot for the Halona Blowhole to start our hike. The trailhead is roughly across the Japanese fishing shrine that is now maintained by Vietnamese Buddhists. There are no colored ribbons to mark the way, but the trail itself is well traveled and hard to miss.

Going up the crater side

We started off on the relatively flat and rocky ridge that connects to the crater walls and then we started the gradual climb up Koko Crater.

The arch

The rock arch spans a gulch that is roughly in the middle of the climb up the crater. The easiest way to get over the arch is on the left hand side where there are some steps that look like they were carved into the tuff lava.

Hanauma Bay

The climb and our breathing got a little harder after the arch, as we neared the top, Hanauma Bay and Koko Head came into view. We also passed three hikers coming down from the top, other than that we had the trail all to ourselves. Besides Mount Olympus, going up the stairs at Koko Crater was the only other hike I’ve done that has so much foot traffic.

Makapu'u Point

Headed towards the summit, we could see the botanical garden inside the crater and Makapu’u Point in the distance.

View from the top

We made the summit at 1,208 feet in under an hour. As usual, the top was packed with people, attesting to it’s popularity with the local crowd. 

Going down the rim

Going down the crater rim was marked with a gradual descent punctuated by rocky formations that we either climbed or contoured around.

Crater rim wall

We came across part of the crater wall that looked like it was fractured or split apart. That’s what I love about ridge hikes, you get fantastic views and interesting scenery to boot. You also have to stay focused and keep that mental edge, otherwise you may fall off that edge.

Koko Crater Botanical Garden

We ended the two and a half hour hike amongst the sweet smell of plumeria trees in Koko Crater Botanical Garden.

Koko Crater at 1,028 feet high, dominates the Hawaii Kai skyline. If you look closely, you can usually find ants of people going up and down the mountain. After reading countless posts about what a great hike this is and how it beats a stairmaster, I decided to give it a try. After driving into Koko Head District Park and parking next to the baseball field named after Mike Goeas, a former police officer that founded the PAL football program in Hawaii Kai. I followed the road until I hit the tram tracks that starts the climb towards Koko Crater.

Trailhead

There are reputedly 1,048 railroad ties or steps to the top. The tram tracks was built by the Army during WW2 to haul supplies to the top of the mountain. And no, I didn’t bother to count the steps going up. I was too busy just trying to make it to the top!

The Bridge

About half-way to the top, the ground gives way to a gully that’s about 10-15 feet deep. So now, the tram tracks serves as a bridge of sorts. It was around this point, that I kicked myself for leaving my water bottle in the car. I thought I wouldn’t need it. Wrong! The sun beating down on me didn’t help matters much. I thought about going back to get the water, but knew if I did, that I wouldn’t be coming back. So after a break, I continued my climb to the top.

Back on solid ground!

About 50 feet or so, the gully ends and the tracks are back on solid ground. For those leery of heights or not as sure-footed, there is a trail to the right that goes around the gully and connects to the tracks when it meets solid ground again.

Give me some water!

I felt sorry for this dog, as he didn’t look too keen on making this climb. At least, he was going back down. Coming down, hikers and dogs have the right of way, just step to the side and let them pass.

Are we there yet?

I believe this is the steepest part of the mountain. When I finally made it to the top, I found two older women chatting away, congratulating me on getting to the top. They told me that they do this every week! I really need to get back into shape!

View from the top

It took me roughly 35 minutes to make it to the top of Koko Crater or Pu’u Ma’i. I heard the “regulars” shoot for 20 minutes and some even run up and down the tracks. I was happy with my time! You can see Kuapa Pond in Hawaii Kai and Diamond Head in the distance from the top of the abandoned heliport.

Hanauma Bay

Looking to the left, you can see the breached volcano crater of Hanauma Bay and the companion tuff cone of Koko Head.

Botanical Garden

Peering over the crater rim of 200 acres of the Koko Crater Botanical Garden, looks all the same from up here! You can also see Makapu’u Point in the distance. After soaking in the views, it was time to go back down and guzzle my water that I left in my car! This hike is relatively easy, as it’s straight going up and down, parts of the ground supporting the tram tracks are eroded and you just have to watch your step, especially going down and always bring water.
