The Kaumana Caves were formed by the 1881 lava flow from Mauna Loa, a volcano known for its frequent and powerful eruptions. As the lava advanced, it created a network of underground tunnels near Hilo on the Big Island of Hawaii. This fascinating natural process began when the lava flow’s outer layers started to cool and solidify, forming a crust. Meanwhile, the molten lava continued to flow beneath this hardened surface, carving out a hollow tube. When the eruption subsided, the remaining lava drained from the tunnel, leaving behind the remarkable Kaumana Caves that visitors can explore today.

In 1881, Hilo faced an imminent threat as the Mauna Loa lava flow made its way toward the town. As the lava inched closer, residents feared that their homes and businesses would be engulfed by the destructive force. The town was in a state of high alert, with limited means of stopping the natural disaster heading its way.

As the situation in Hilo grew more dire, Princess Ruth Keʻelikōlani, a member of the Hawaiian monarchy, stepped in. Deeply rooted in Hawaiian traditions and beliefs, Princess Ruth was devoted to Pele, the goddess of volcanoes. According to local legend, she traveled to the lava flow and performed prayers and rituals, asking Pele to spare the town from destruction. In a turn of events that many considered miraculous, the lava flow halted just a few miles from Hilo, and the town was saved. Many believe that Princess Ruth’s intervention and prayers to Pele were the reason for this sudden stoppage.

Today, Kaumana Caves have transformed into a must-visit spot for travelers and adventurers. Visitors are drawn to the opportunity to explore these underground lava tubes and witness firsthand the stunning formations that were shaped by molten lava over a century ago. The caves’ unpolished and raw beauty offers a unique and immersive experience for anyone fascinated by Hawaii’s volcanic landscape.

Exploring Kaumana Caves offers a rugged adventure through a natural lava tube with uneven floors, cool temperatures, and low-light conditions.

Though the cave is mostly barren inside, the surrounding area may reveal some unique flora and fauna, such as native ferns growing near the entrance and small insects that have adapted to the cave’s cool, damp conditions.
