Planning a trip to the Big Island? Just south of the main entrance to Hawai‘i Volcanoes National Park, there’s a lesser-known area that most visitors miss. The Kahuku Unit offers an entirely different experience, one that feels quieter, wilder, and more connected to the island’s living landscape. With wide-open views, rolling pastures, ancient lava flows, and striking cinder cones, it’s a must for travelers looking to go beyond the crowds.
If you’re staying at our Volcano vacation rental, you’re perfectly positioned to explore both the main park entrance and the Kahuku Unit, giving you the best of both worlds.
The Storied Past of the Kahuku Unit
Before it became part of Hawaiʻi Volcanoes National Park, the Kahuku Unit lived many lives, and each one left a mark on the landscape. Located on the dramatic slopes of Mauna Loa, Kahuku was once one of the largest cattle ranches in the islands, stretching across more than 116,000 acres. For over 150 years, ranchers raised cattle here, shipping out hides and beef while contending with the ever-present reality of volcanic eruptions.
But Kahuku’s story begins much earlier than the ranching era. Native Hawaiians once lived and worked on this land, farming the fertile ʻāina and gathering resources from the surrounding forests. Lava flows and earthquakes were a part of life, shaping not only the terrain but also the stories and practices passed down through generations.
In the 20th century, Kahuku played a brief role in military history, too. During World War II, it served as a training site known as Camp Kahuku, and if you walk some of the trails today, you might spot old bunkers or remnants of military roads tucked into the brush.
It wasn’t until 2003 that this rugged landscape officially became part of the national park. Since then, it’s been protected and opened up for exploration to the public.

Tips for Visiting the Kahuku Unit
Kahuku is rich in cultural significance and natural beauty. To help preserve its beauty and significance, always stay on marked trails, avoid disturbing wildlife or native plants, and carry out anything you bring in. Take only photos. This land holds generations of history, and protecting it ensures others can experience it, too.
If you’re planning your visit around photography or hiking, mornings are often the best time to go. The skies tend to be clearer, and the light is perfect for capturing panoramic views of Mauna Loa and the rolling pastures below. Afternoons may bring some cloud cover, but it only adds to the drama of the landscape.
At 3,000–4,000 feet above sea level, Kahuku is noticeably cooler than the coast. Pack layers, wear sturdy hiking shoes, and bring plenty of water as conditions can change quickly, especially on the longer trails.
