Hiking Wiliwilinui to Hahaione Pyramid

Somebody asked me to hike this section today for their birthday. I often get confused for the Make-A-Wish Foundation.

Thanks to Scott, Susan and Tessa for shuttling us to the trail nestled in the luxury neighborhood of Waialae Iki that was founded in the 1960s.

Looking back at the sunrise shimmering over the Pacific Ocean as we hiked up the trail that was originally a service road built by the US Army in 1941.

Reverse tug of war, where the mountain pulls you up the hill.

Somebody thought this was the end of the line and were about to turn around and call it a day. He was sadly mistaken.

Staggering out the group to prevent trail erosion or maintain social pacing or was that distancing. Is that even a thing anymore?

And then they were ten. Edgar, Joyce, Mari, Marilyn, Scott and Tessa departed the summit to go back down the trail. They had places to go and things to do and being on the KST was not one of them.

Hawaii Loa Summit

Most people eat trail mix or energy bars on the hike for energy. Ferlino eats rice. Not adobo with rice. Not multi-grain rice. Not brown rice. Just white rice. Carbs.

Our birthday hike covered 6.86 miles with a fun and large group. Post hike birthday dinner at Gyotaku where we arrived too late for the early bird specials. Happy Birthday Susan!

Note: I have been made aware that some hikers have been using my blog as a hiking guide and getting lost on the trails. Please note that this blog was made to document the hike for the crew(s) that did it. That is why some of my comments will seem to have no relevance or meaning to anybody outside of the crew(s) that hiked that trail. My blog was never meant as a hiking guide, so please do not treat it as such. If you find inspiration and entertainment from these hikes, that is more than enough. If you plan on replicating these hikes, do so in the knowledge that you should do your own research accordingly as trail conditions, access, legalities and so forth are constantly in flux. What was current today is most likely yesterdays news. Please be prepared to accept any risks and responsibilities on your own as you should know your own limitations, experience and abilities before you even set foot on a trail, as even the “simplest” or “easiest” of trails can present potential pitfalls for even the most “experienced” hikers. One should also always let somebody know of your hiking plans in case something doesn’t go as planned, better safe than sorry.

Plan A was dismissed for lack of permit, Plan B was discarded due to lack of commitment, and so it was down to Plan C today. Thanks to Tessa for dropping us off at the park as they opened the gates, perfect timing as it saved us 10 minutes of walking. We are part-time hikers. […]

Rain was drenching the islands for almost a week, you would think the stream levels would be overflowing. One would think. We all met up on the street that was named after the California Colony that was founded by families from the 31st state who came to farm pineapples and fruits in the early 1900s. […]

Somebody waited five years to finish this section. Good things come to those who wait. Thanks to Alex and Lilia for dropping Chico, Katie and myself off at our starting point today. Inside or outside trail? Group photo in the hole in the cliff, that was witness to the Battle of Nu’uanu in 1795 that […]

We killed two birds with one stone by having our #15 perimeter walk and celebrating Tessa’s birthday all wrapped up in one day. The group met up at Chico’s house while Santa checked out his Harley with his two elves as he gets ready for his Christmas Toys for Tots ride. Thanks to Blaine, David […]

We all met up to do a birthday hike for Edgar and explore upstream like so many migrating and spawning salmon. Thanks to Matt, the grounded paraglider, for picking us up by the church founded by Felix Manalo, whose views and practices widely diverge from mainstream Catholicism. Warming up with pseudo tai chi where superficiality […]

I decided to recreate a hike that we did for Chico’s finish almost two years ago. Too close for comfort. Parked in the neighborhood that started off as the Manana ahupua’a which was turned into pineapple fields and evolved into the residential neighborhood as it exists today. Solitary hike today as the usual suspects had […]

Our sandbar sailing got cancelled due to mechanical and physical breakdowns and so we pulled a magic trick. We turned a two hour hike into a full day. How? Read on impatient ones. We all met up despite the annoying church slut saying it was raining and perhaps a waterfall hike was in order. What […]

I had a vacation day to burn off so I spent it in the mountains. Checked into the gated neighborhood that came into its own in the 1980s, this entire ridge was once home to Wiliwili trees that are now replaced by upscale homes. Going up the stairs that were collecting mud puddles, missing the […]

The random dumping of rain over the weekend resulted in cancellation of the original hike and its easy peasy lemon squeezy replacement. We met up deep in Manoa Valley under a constant pitter patter of rain and paid our four dollars to park inside while somebody parked in the neighborhood. Going through the shipping container […]
