Caves aren’t necessarily the first natural feature that comes to mind when you think of Hawaii. But there are quite a few of them—many underwater, and some tucked away on dry land. Upper Makua Cave is one of the latter. And while its modest size might make you wonder, is this really a cave? But the Instagram-worthy framing of the coastline from within quickly turns that question into a non-issue.

Know before you go
The Lower Makua Cave is also in this area and is just a few steps from where you’ll park. It's much larger and actually feels like a real cave.
There’s unexploded ordinance in this area left over from WWII. While I haven’t heard of any incidents, it’s something to be aware of. This area may be subject to government restrictions.
This trail has steep sections and is likely overgrown. It's not exposed like some ridge hikes, but you may be required to scramble up some rock and rub up against some tall grass.

The Trail
Park at the Kaneana dirt lot, marked by a prominent sign. I highly recommend checking out the lower cave first. It’s significantly larger and has a real cavern feel to it.
🧭 From the lot, head north along the highway for a few hundred feet. Look for a clear opening in the brush on your right. If you pass the speed limit sign, you’ve gone too far.
As you ascend, you’ll follow a few well-worn paths leading to a ridge just below where the brush meets the steeper rock.
This trail is likely to be overgrown, so long pants aren’t a bad idea.
Here's a look at one of the steeper inclines.. You may need to scramble and use your hands.
Eventually, the trail will level out on a ridge. When you feel like you can’t go up anymore, that’s your cue to take a sharp right. A narrow path hugs the ridge, leading you back toward the coastline. It narrows slightly, but nothing too sketchy.
It’s a good time to slow down and soak in the views. This is one of the most scenic portions of the hike.
You’ll come across two “caves.” The first cave is marked by a distinctive tree.
Keep going a bit farther and you’ll reach the main cave—the real prize. It might not be massive, but the view framed by the cave’s opening is downright stunning.
SS Reflections
I’ve always felt like hiking in Hawaii is all about finding those hidden gems. There are waterfalls, pillboxes, and yes, even caves. Some of these more natural ones feel like it was mother nature just creating a scavenger hunt for us. Upper Makua isn’t the most famous or dramatic trail, but it’s a perfect example of how even a short, low-key hike can lead to something special.
