The Hawaiian Islands are full of beautiful geographic anomalies, including caves of all varieties. From lava tubes caused by volcanic eruptions to coastal caves carved by the ocean, these caves found across the islands are each stunning in their own way. Today, however, we’re taking you on an unforgettable journey to an off-limits cave most people will never visit. Unlike most caves in the Aloha State, this gem doesn’t require you to head underground or underwater. In fact, this cave is only accessible via a steep and dangerous hike up a mountain.

Nestled along Oahu’s leeward coast north of Waianae, near where Farrington Highway ends at Kaena Point, is Kaneana Cave, a place of absolute mystery. We explored this cave’s haunting legends in this article, but today, we’re taking you above Kaneana Cave to the Upper Makua Cave, an off-limits gem with stunning views.

Measuring in at less than a mile, this heavily trafficked out and back trail is not only quite difficult but is located on federal property where live ammunition is found to this day and is, essentially, forbidden.

Many people wouldn’t even refer to the Makua Cave as a hike, and we might have to agree with them — the nearly vertical path often feels more like a rock climb than a "hike."

The trail is rated as difficult, and you shouldn’t attempt to climb if you aren’t confident in your abilities and willing to face the consequences. You can, however, simply admire the views from these images and daydream about Hawaii’s gorgeous landscapes.
