Hawaii Volcanoes National Park’s Kahuku Unit is a hiking area in Ocean View, on the Big Island’s Kaʻū side. Its trails cross grassy meadows, lush forest and jagged lava fields, with views toward the coastline, cliffs and sea caves. More than six routes range from under half a mile to over five miles, so you can choose a short walk or spend the day exploring. Ask at the visitor center for trail suggestions, and bring food: there are no nearby cafes or restaurants.
Trails across ranch country
The Kahuku Unit occupies former ranch land in the uplands above Highway 11, past Nā‘ālehu. Its landscape differs from the lower parts of the national park and the surrounding Kaʻū region: trails move through grassy meadows and rolling hills as well as forest and jagged volcanic rock.
There are more than six hikes, from routes under half a mile to those longer than five miles. Some paths are mostly grassy, while others cross rougher, rocky ground. A two-mile route, Puʻu o Lokuana Trail, is one option. Park staff at the visitor center can help you choose a hike for the time and terrain you have in mind.
Volcanic terrain and coastal views
The trails reveal several sides of the unit, from volcanic rock fields and crater views to cliffs overlooking sea caves and breaking waves. Routes mentioned in the area include the Petroglyph Trail, a lava tube trail and a path down to a crater floor. Conditions and effort vary: one crater-pit route climbs nearly 1,000 feet over 2.5 miles, so pick a trail that suits your fitness and footwear.
A small guide booklet about the Puʻu o Lokuana Trail can help explain the area’s geology and history as you walk. The visitor center is also a place to ask staff about the landscape and its cultural context, including traditions connected with Pele.
