Pu'u Mai (Ferlino's Birthday Hike)

The birthday boy wanted a short hike due to time constraints, so the venue picked was the extinct tuff cone also known by is original Hawaiian name of Kohelepelepe.

We met up in the 60 acre botanical garden founded in 1958 to celebrate the early birthday of Ferlino, since he won’t be on island to celebrate his actual date of birth. Just like a birthday wish, his birthday balloon went up in the air right before the start of the hike. Face palm.

Hats off to the Kokonut Koalition, a volunteer group formed in 2018 that fixed decades of neglect that led to the deterioration of the steps. It’s really amazing to see, especially if you hiked the steps before all the hard work that fixed it. Night and Day.

We had our lunch at Tex808 Hawaii where Aida joined the group. Our breeze of a hike covered less than two miles that was filled with good times and fun friends. Happy Birthday Ferlino! Next time, hold onto that balloon!

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.

We spent today roaming a different set of hills for an early easy birthday hike. A lot of trails were considered after a severe thunderstorm cell had pounded the island yesterday.

We camped this weekend in the mountains to find out how the aina had weathered the back to back storms. Nothing like first hand experience instead of second hand reporting.

We all met up and parked outside the protected coastline that are home to sand dunes, sea arch and caves, and native plants and wildlife. Passing several mass wastings that were triggered by the […]
