We had so much fun exploring the Kaumana lava tube the first time that we had to return to explore it further.
As we descended down to the opening of the cave, we passed in front of the Eastern entrance to the cavern, which we had explored last time.
After walking down the stairs to the floor of the lava tube, we turned left towards the western mouth of the cave. We had briefly inspected this chamber during our last visit, however we had not notice an obvious path and assumed the ceiling had caved in.
After checking the entrance to the cavern a bit more rigorously, we noticed a narrow gap that could fit through. Uncertain if this shaft would take us anywhere interesting, we hesitated to proceed.
One of the smallest (and perhaps bravest) members of our expedition was able to advance with ease. She pushed forward to determine if it would be worth the rest of the group continuing or if we should consider turning around to explore the eastern shaft. After a few moments of silence, waiting in the blackest darkness we had experienced in a long time (we thought it would be fun to turn our lights off for a moment), we heard her muffled voice inviting us to join her deeper in the cave. She had found the rest of the lava tube.
Watch you head! Certain sections, near the beginning, had some pretty narrow passages. Loose stones scattered across segments of the lava tube’s floor made for some wobbly footing.
We were shocked to discover a 30-40ft tall ceiling in the first large chamber that we reached. This was especially surprising, as I did not even think we were that deep. I’m uncertain how thick the roof of the cavern was, but dangling plant roots had managed to grow through it. Large stones, observed on the floor, most likely fell from above, so proceed with caution.
It was wild to think that the ground we were walking on was literally a river of magma around 140 years ago.
As we navigated deeper underground, we came upon a proper cave-in, where the ceiling had completely opened up to the jungle above.
As dangerous as a collapsed chamber probably is (because of the risk of falling rocks), the group was immediately drawn to it, like moths to a flame…
The Kaumana skylight only takes about 15-20min to reach. At its surface, we were immersed into a lush forest speckled with red anthurium plants (commonly referred to as lava rock plants). Because of how dense the vegetation was, we did not feel confident wandering too far away from the cave. We were able to go a bit further up the lava tube but not much.
Kaumana cave state park is relatively accommodating, considering there is no entry fee (I love free adventures). Parking is provided at the surface, as well as restrooms. The most important thing you will need to remember is to BRING A FLASHLIGHT!!!! There are absolutely no lights inside. You will pass through multiple dark zones, which would be extremely difficult to navigate in the pitch black.
If you ever find yourself on the East side of the the Big Island, this lava tube is definitely worth the detour. It’s about 10 minutes from Hilo and near mile marker 4, if you are driving up Kaumana Dr.

Hi. I was stationed in Oahu from 1988 to 92 and hiked all over the island. Became friends with some locals and they took to to some special places. 1) Have you ever heard of the “The Fortress?” Its over on the west range, above (north) “Nanakuli Forest Preserve.” Send me an email and I’ll give you coordinates. 2) I’ve hike to the top of Mt. Kaala (highest point on Oahu) and hear now that there is a trail there. Is that true? Last I enjoyed you post “Secret Abandon Bunker.” did not know of its existance. Where is it?
Oh wow that sounds awesome! I have not heard of the fortress… However I have heard of a bunker somewhere up in those mountains, but I believe it is now on a private youth camp’s property. I’ve Emailed them to inquire about the possibility of visiting their grounds, but they never responded :/ I would love to hear more about this “fortress” though. I will shoot you an Email.
I did hike to the top of Mt. Kaala once, from the west side. It took us all day and was pretty sketchy. I’ve heard of other trails from Scofield and from Peacock flats direction (but they take much longer). I have some friends that have permits to drive up there too. I guess there is a military station up there, with a really nice paved road that you can drive up (with the proper clearance). There are many secret bunkers out here that people have asked me not to divulge any locations. Generally my posts have enough subtle clues to find them though (with a little internet research). There are some bunkers I’ve been to afraid to even post about…
