About Kahūnā Falls
Tucked into the wet, emerald rainforest of Hawaiʻi Island, Kahūnā Falls drops roughly 400 feet down a steep, verdant cliff and offers a quieter counterpart to its more famous neighbor, ʻAkaka Falls. The cascade sits within ʻAkaka Falls State Park, about 11 miles (18 km) north of Hilo and accessed from the Hawaii Belt Road (Route 19) at the end of Hawaii Route 220. Framed by dense tropical growth—ferns, orchids and bamboo—Kahūnā is a rewarding sight for photographers and hikers seeking a lush, relatively short outing. Visitors often combine a stop at Kahūnā with views of the park’s namesake, 442-foot ʻAkaka Falls, which is named for Chief 'Akaka-o-ka-nī'au-oi'o-i-ka-wao. The setting feels distinctly Hawaiian: a compact, well-tended park where powerful waterfalls and cultural history meet amid easy, rainforest trails that showcase the island’s endemic plant life.
The Setting
Kahūnā Falls sits at 1,027 feet along the Hakalau Stream, in the foothills of Hawaii. At 400 feet, it is among the taller waterfalls in Hawaii.
Height: 400 feet
