Hiking Mauna Loa Observatory Trail

We woke up to a slightly chilly morning at 4,000′ elevation hoping that all our bodies were properly acclimatized for our high altitude trek ahead of us. Wishful thinking.

The group stretching for what they thought was going to be a three day hike and in the end it turned out to be for a five minute walk to breakfast.

Early birds get to wait for Hawaiian time. Sugar and cream in your coffee? Nah. Locals use shoyu. Kikkoman.

The bathroom had a vacancy that Narissa wanted to fill. Calisthenics wasn’t helping matters much.

Looking at the different colorations and textures of lava that made up the lunar like landscape; pahoehoe (smooth) and a’a (rough), chocolate fudge and chocolate thunder.

We snagged the last parking stall as a bicyclist blocked us in with her “photo ransom.”

Nothing beats a rubber slippah tripod to take your group photo at the start of our 11,140′ elevation hike. Matt also grabbed the bag of musubi’s that Justin had stashed for us.

I caught up with Justin’s group as they had took the jeep route which would eventually reconnect back to the trail. I needed the extra exercise anyway.

Our two groups met at 11,680′ elevation and the reduced atmospheric pressure had taken its toll on some of the group. Less oxygen to the lungs resulted in headaches, lightheadedness, nausea and poor judgment. Some had it worse than others. As a result, the group separated into the ascenders and descenders.

It soon become obvious that high altitude sickness had claimed another member in our group. Faced with a dwindling group and time, we decided to turn back and throw in the towel at 12,305’elevation. We called ahead to make sure our rides didn’t leave without us. No bueno to be walking another 17 miles down to sea level.

Our attempted hike up the long mountain became abbreviated into a short climb up and down.

We decided to make the most of our limited time on the mountain and spent some of it at the cavernous lava tube marked by two large stacks of rocks. Photo by Kurry Wong.

Making our way back down the trail. The only remedy for altitude sickness is to descend back down to a lower elevation where the symptoms will eventually subside.

Back to our trucks and cold beer for those with a taste for it. Post hike meal at Hawaiian Style Cafe where the wait was long but tolerable.

We returned to our five star accommodations for the night, Matt even got a late night dish of noodles and real shrimp. All joking aside, much appreciation to Quan’s cousins, Binh and Huy, for putting us up at such short notice and letting us borrow their truck.

Our hike up to an active volcano clocked in under six miles. While it fell short of our intended goal, we all got down safely and had a good time and lived to hike another day.

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.
