Escape to 43.37 acres of scenic pastureland on the slopes of Mauna Kea in the historic Kukaiau area. Once part of one of Hawaiʻi’s oldest working ranches, this legacy property offers open grazing lands, privacy, and panoramic views in a cool upcountry climate. What makes this property truly unique is the presence of Kukaiau Cave — a scientifically recognized cave system formed by water erosion rather than lava flow, an extremely rare occurrence in Hawaiʻi. Extending over 1,000 meters underground, the cave features underground streams, sculpted waterfalls, plunge pools, and geologic formations found nowhere else. Documented in national scientific journals, Kukaiau Cave is one of the first and most significant examples of a water-eroded cave in Mauna Kea lava flows. Whether you're looking for a private sanctuary, an ecological preserve, or a one-of-a-kind landholding, this extraordinary property offers a deep connection to Hawaiʻi’s natural and geologic history.
