A rolling, pastoral landscape on the slopes of the largest volcano on the planet
Located on the volatile shoulders of Mauna Loa, the Kahuku Ranch was once one of the biggest cattle ranches in Hawaiʻi, producing beef and hides for more than 150 years. The apparent tranquility of ranch-life, however, was punctuated by volcanic violence that continues to transform the land to this day.
Share in the wonders of this 116,000 acre landscape shaped by both man and nature.
