Hiking Nu'uanu Pali Lookout to Kalihi Valley

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.

Whipping winds were blowing dirt into any exposed open orifices. Anybody got Visine?

Chico pulling himself up the constantly crumbling hill that is still more preferable than the original contour route IMO. To each their own.

Adriana, Stacy and Susana soon caught up with us at the 2,700′ top and decided to join us to the finish line. The more the merrier.

Sliding our way down into what some hikers argue is one of the hardest sections of the KST. I would argue it’s Diamond Head, but then again the iconic tuff cone is not part of the mountain range system.

Waiting for the rest of the group to descend down the wall which is notorious for falling rocks, I can bear witness to that.

Katie and Susana under the shadow of the Can Opener and what I like to call the “Bulging Fridge.” A sizeable rock that seems to jut out inch by inch every time I pay a visit to this spot. Or maybe I just have an active imagination.

Pete Clines the legendary hiker was the one that gave these “silly names” to these obstacles on Kalihi Saddle so as to make them less intimidating.

Descending down into Kalihi Valley, that are home to a colony of Australian rock wallabies, that escaped from the private zoo of Richard Trent in 1916. The last survey conducted in the 1990s pegged the marsupial population to number in the 70s.

Our KST completion hike covered 2.97 miles through two saddles and unexpected company. Congratulations again to Katie for a finish that was long in the making. Post hike meal at Nalu Health Bar & Cafe where I was pleasantly surprised by the menu offerings.

Photos taken by Adriana Hunter, Chico Cantu, Katie Lockerton, Stacy Paquette, Susana Escobar and yours truly. Not necessarily in order.

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.
