History and Background
Explore a piece of Hawaiian history dating back over 600 years. You’ll find evidence of early Hawaiians who used this land for farming and hunting, as well as the supporters of Kamehameha the Great who retreated here. In 1793, cattle were introduced and paniolo were hired around 1830. Unfortunately, in 1868, a volcanic eruption destroyed Robert Brown’s home and ranch. During WWII, there was also a secret radar station located at Pu’u o Lokuana Cinder Cone. Finally, from 1912-1947, Park Ranch owned the area until it became public land in 2003.
