Waiū o Hina lava tube was formed by molten lava flowing from Mauna Loa, the largest active volcano on earth. When the eruption ceased, all of the lava drained from this tube—some into the ocean—leaving a hollow tube.

Lava tubes are found throughout the island and hold great cultural significance for the Native Hawaiian people. In ancient times, lava tubes were important for shelter from the elements and for refuge during times of war. In some lava tubes, water drips from the ceiling, filtered through porous lava rock and would serve as an important source of fresh water and collected in ipu (gourds). Lava tubes were also used as burial caves and many of these sacred burial caves are kapu (forbidden) and protected today.
